Sikhism ( //); Punjabi: ਸਿੱਖੀ or Sikhi (Sikkhī, [ˈsɪkːʰiː], from ਸਿੱਖ, Sikh, 'disciple', 'seeker', or 'learner'), [i] is a monotheistic religion that originated in the Punjab region of the Indian subcontinent [ii] around the end of the 15th century CE.       One of the youngest of the major religions and the world's fifth-largest organized religion,  it comprises about 25 million Sikhs as of the early-21st century [update].  But however according to rough estimates, there are around 12-15 crore Nanak Naam Lewas people across the world who also believe in 10 Sikh Gurus and Shri Guru Granth Sahib. 
Sikhism developed from the spiritual teachings of Guru Nanak, the first Guru (1469–1539),  and of the nine Sikh Gurus who succeeded him. The tenth Guru, Guru Gobind Singh (1676-1708), named the Sikh scripture Guru Granth Sahib as his successor, bringing to a close the line of human Gurus and establishing the scripture as the eternal, religious spiritual guide for Sikhs.    Guru Nanak taught that living an "active, creative, and practical life" of "truthfulness, fidelity, self-control and purity" is above the metaphysical truth, and that the ideal man "establishes union with God, knows His Will, and carries out that Will".  Guru Hargobind, the sixth Sikh Guru (1606-1644), established the concept of the mutual co-existence of the miri (political/temporal) and piri (spiritual) realms. 
The Sikh scripture opens with the Mul Mantar (ਮੂਲ ਮੰਤਰ), fundamental prayer about ik onkar (ੴ, ' One God').   The core beliefs of Sikhism, articulated in the Guru Granth Sahib, include faith and meditation on the name of the one creator; divine unity and equality of all humankind; engaging in seva (' selfless service'); striving for justice for the benefit and prosperity of all; and honest conduct and livelihood while living a householder's life.    Following this standard, Sikhism rejects claims that any particular religious tradition has a monopoly on Absolute Truth. [iii] 
Sikhism emphasizes simran (ਸਿਮਰਨ, meditation and remembrance of the words of God),  which can be expressed musically through kirtan, or internally through naam japna ('meditation on His name') as a means to feel God's presence. It teaches followers to transform the " Five Thieves" (i.e. lust, rage, greed, attachment, and ego). 
The religion developed and evolved in times of religious persecution, gaining converts from both Hinduism and Islam.  Mughal rulers of India tortured and executed two of the Sikh gurus— Guru Arjan (1563–1605) and Guru Tegh Bahadur (1621–1675)—after they refused to convert to Islam.      The persecution of Sikhs triggered the founding of the Khalsa - by Guru Gobind Singh in 1699 - as an order to protect the freedom of conscience and religion,   with members expressing the qualities of a Sant-Sipāhī—a 'saint-soldier'.  
The majority of Sikh scriptures were originally written in the alphabet of Gurmukhī, a script standardised by Guru Angad out of Laṇḍā scripts historically used in present day Pakistan and North India.   Adherents of Sikhism are known as Sikhs, meaning 'students' or 'disciples' of the Guru. The anglicised word Sikhism derives from the Punjabi verb Sikhi, which connotes the "temporal path of learning" and is rooted in the word sikhana ('to learn').  
A Sikh can be defined as any human being who faithfully believes in:
i. One Formless Being
ii. Ten Gurus, from Guru Nanak Sahib to Guru Gobind Singh Sahib,
iii. The Guru Granth Sahib,
iv. The utterances and teachings of the ten Gurus and
v. the baptism bequeathed by the tenth Guru, and who does not owe allegiance to any other religion, is a Sikh.
The basis of Sikhism lies in the teachings of Guru Nanak and his successors. Some sources call Sikhism a monotheistic religion,   while others call it a monistic and panentheistic religion.    According to Nesbitt (2005), English renderings of Sikhism as a monotheistic religion "tend misleadingly to reinforce a Semitic understanding of monotheism, rather than Guru Nanak's mystical awareness of the one that is expressed through the many. However, what is not in doubt is the emphasis on 'one'." 
In Sikhism, the concept of "God" is Waheguru ('wondrous Teacher') considered to be nirankar ('shapeless'), akal ('timeless'), karta purakh ('The Creator'), and agam agochar ('incomprehensible and invisible').  The Sikh scripture begins with ik onkar (ੴ), which refers to the "formless one",  :227 understood in the Sikh tradition as monotheistic unity of God.  Sikh ethics emphasize the congruence between spiritual development and everyday moral conduct. Its founder Guru Nanak summarized this perspective: :234
Truth is the highest virtue, but higher still is truthful living.
Sikhism lays emphasis on Ėk nūr te sab jag upjiā, 'From the one light, the entire universe welled up.'
God in Sikhism is known as ik onkar (ੴ), the One Supreme Reality, the One Creator or the all-pervading spirit (i.e. God).  This spirit has no gender in Sikhism, though translations may present it as masculine. It is also akaal purkh ('beyond time and space') and nirankar ('without form'). In addition, Nanak wrote that there are many worlds on which it has created life. 
ੴ ਸਤਿ ਨਾਮੁ ਕਰਤਾ ਪੁਰਖੁ ਨਿਰਭਉ ਨਿਰਵੈਰੁ ਅਕਾਲ ਮੂਰਤਿ ਅਜੂਨੀ ਸੈਭੰ ਗੁਰ ਪ੍ਰਸਾਦਿ॥
"There is one supreme being, the eternal reality, the creator, without fear and devoid of enmity, immortal, never incarnated, self-existent, known by grace through the true Guru."
|— Sri Guru Granth Sahib (17th c.), p. 1|
Māyā, defined as a temporary illusion or "unreality", is one of the core deviations from the pursuit of God and salvation: where worldly attractions which give only illusory temporary satisfaction and pain which distract the process of the devotion of God. However, Nanak emphasised māyā as not a reference to the unreality of the world, but of its values. In Sikhism, the influences of ego, anger, greed, attachment, and lust, known as the pānj chor (' five thieves'), are believed to be particularly distracting and hurtful. Sikhs believe the world is currently in a state of kali yuga ('age of darkness') because the world is led astray by the love of and attachment to maya.  The fate of people vulnerable to the five thieves, is separation from God, and the situation may be remedied only after intensive and relentless devotion. 
According to Guru Nanak the supreme purpose of human life is to reconnect with Akal ('The Timeless One;), however, egotism is the biggest barrier in doing this. Using the Guru's teaching remembrance of nām (the divine Name of the Lord)   leads to the end of egotism. Guru Nanak designated the word Guru ('teacher')  to mean the voice of "the spirit": the source of knowledge and the guide to salvation.  As ik onkar is universally immanent, Guru is indistinguishable from Akal and are one and the same.  One connects with Guru only with accumulation of selfless search of truth.  Ultimately the seeker realises that it is the consciousness within the body which is seeker/follower of the Word that is the true Guru. The human body is just a means to achieve the reunion with Truth.  Once truth starts to shine in a person's heart, the essence of current and past holy books of all religions is understood by the person. 
Guru Nanak's teachings are founded not on a final destination of heaven or hell but on a spiritual union with the Akal which results in salvation or jivanmukti ('enlightenment/liberation within one's lifetime'),  a concept also found in Hinduism.  Guru Gobind Singh makes it clear that human birth is obtained with great fortune, therefore one needs to be able to make the most of this life. 
Sikhs accept reincarnation and karma concepts found in Buddhism, Hinduism, and Jainism, but do not necessarily infer a metaphysical soteriology akin to Buddhism, Hinduism and Jainism.    However, in Sikhism, both karma and liberation "is modified by the concept of God's grace" (nadar, mehar, kirpa, karam, etc.). Guru Nanak states that "the body takes birth because of karma, but salvation is attained through grace."  To get closer to God, Sikhs: avoid the evils of maya; keep the everlasting truth in mind; practice shabad kirtan (musical recitation of hymns); meditate on naam; and serve humanity. Sikhs believe that being in the company of the satsang (association with sat, 'true', people) or sadh sangat is one of the key ways to achieve liberation from the cycles of reincarnation. 
Guru Nanak, the first Sikh Guru and the founder of Sikhism, was a Bhakti saint.  He taught that the most important form of worship is Bhakti (devotion to Bhagvan).  Guru Arjan, in the Sukhmani Sahib, recommended the true religion is one of loving devotion to God.   The Guru Granth Sahib includes suggestions on how a Sikh should perform constant Bhakti.    Some scholars call Sikhism a Bhakti sect of Indian traditions,   adding that it emphasises "nirguni Bhakti," i.e. loving devotion to a divine without qualities or physical form. :1–3   However, Sikhism also accepts the concept of saguni, i.e. a divine with qualities and form.  While Western scholarship generally places Sikhism as arising primarily within a Hindu Bhakti movement milieu while recognizing some Sufi Islamic influences,  :3, 42–3 Indian Sikh scholars disagree and state that Sikhism transcended the environment it emerged from. This is evidenced by the fact that Bhakti traditions did not clearly disassociate from Vedic texts and their cosmologies and metaphysical worldview, while the Sikh tradition clearly disassociated from the Vedic tradition. 
Some Sikh sects outside the Punjab-region of India, such as those found in Maharashtra and Bihar, practice Aarti with lamps during bhakti in a Sikh Gurdwara.   But, most Sikh Gurdwaras forbid aarti (the ceremonial use of lamps) during their bhakti practices. :201
While emphasizing Bhakti, the Sikh Gurus also taught that the spiritual life and secular householder life are intertwined, and not separate. This logically follows from the panentheistic nature of Sikh philosophy.  In Sikh worldview, the everyday world is part of the Infinite Reality, increased spiritual awareness leads to increased and vibrant participation in the everyday world.  Guru Nanak described living an "active, creative, and practical life" of "truthfulness, fidelity, self-control and purity" as being higher than the metaphysical truth. 
The 6th Sikh Guru, Guru Hargobind, after Guru Arjan martyrdom and faced with oppression by the Islamic Mughal Empire, affirmed the philosophy that the political/temporal (Miri) and spiritual (Piri) realms are mutually coexistent.   According to the 9th Sikh Guru, Tegh Bahadur, the ideal Sikh should have both Shakti (power that resides in the temporal), and Bhakti (spiritual meditative qualities). This was developed into the concept of the Saint Soldier by the 10th Sikh Guru, Gobind Singh. 
The concept of man as elaborated by Guru Nanak refines and negates the "monotheistic concept of self/God," and "monotheism becomes almost redundant in the movement and crossings of love."  The goal of man, taught the Sikh Gurus, is to end all dualities of "self and other, I and not-I," attain the "attendant balance of separation-fusion, self-other, action-inaction, attachment-detachment, in the course of daily life." 
Sikhs refer to the hymns of the Gurus as Gurbani ('The Guru's word'). Shabad Kirtan is the singing of Gurbani. The entire verses of Guru Granth Sahib are written in a form of poetry and rhyme to be recited in thirty one Ragas of the Classical Indian Music as specified. However, the exponents of these are rarely to be found amongst the Sikhs who are conversant with all the Ragas in the Guru Granth Sahib. Guru Nanak started the Shabad Kirtan tradition and taught that listening to kirtan is a powerful way to achieve tranquility while meditating; Singing of the glories of the Supreme Timeless One (God) with devotion is the most effective way to come in communion with the Supreme Timeless One.  The three morning prayers for Sikhs consist of Japji Sahib, Jaap Sahib and Tav-Prasad Savaiye.  Baptised Sikhs – Amritdharis, rise early and meditate and then recite all the Five Banis of Nitnem before breakfast.
A key practice by Sikhs is remembrance  of the Divine Name WaheGuru (Naam – the Name of the Lord).  This contemplation is done through Nām Japna (repetition of the divine name) or Naam Simran (remembrance of the divine Name through recitation).   The verbal repetition of the name of God or a sacred syllable has been an ancient established practice in religious traditions in India, however, Sikhism developed Naam-simran as an important Bhakti practice.    Guru Nanak's ideal is the total exposure of one's being to the divine Name and a total conforming to Dharma or the "Divine Order". Nanak described the result of the disciplined application of nām simraṇ as a "growing towards and into God" through a gradual process of five stages. The last of these is sach khaṇḍ (The Realm of Truth) – the final union of the spirit with God. 
The Sikh Gurus taught that by constantly remembering the divine name (naam simran) and through selfless service, or sēvā, the devotee overcomes egotism ( Haumai). This, it states, is the primary root of five evil impulses and the cycle of birth and death.  
Service in Sikhism takes three forms: "Tan" – physical service; "Man" – mental service (such as studying to help others); and "Dhan" – material service.  Sikhism stresses kirat karō: that is "honest work". Sikh teachings also stress the concept of sharing, or vaṇḍ chakkō, giving to the needy for the benefit of the community. 
The term for justice in the Sikh tradition is "Niau".  It is related to the term " dharam" which in Sikhism connotes 'moral order' and righteousness.  According to the Tenth Sikh Guru Guru Gobind Singh, states Pashaura Singh – a professor of Sikh Studies, "one must first try all the peaceful means of negotiation in the pursuit of justice" and if these fail then it is legitimate to "draw the sword in defense of righteousness".  Sikhism considers "an attack on dharam is an attack on justice, on righteousness, and on the moral order generally" and the dharam "must be defended at all costs".  The divine name is its antidote for pain and vices. Forgiveness is taught as a virtue in Sikhism, yet it also teaches its faithful to shun those with evil intentions and to pick up the sword to fight injustice and religious persecution. 
Sikhism does not differentiate religious obligations by gender. God in Sikhism has no gender, and the Sikh scripture does not discriminate against women, nor bar them from any roles.  Women in Sikhism have been in positions of leadership, including leading in wars and issued orders or hukamnamas.   
The term Guru comes from the Sanskrit gurū, meaning teacher, guide, or mentor. The traditions and philosophy of Sikhism were established by ten Gurus from 1469 to 1708.   Each Guru added to and reinforced the message taught by the previous, resulting in the creation of the Sikh religion. Guru Nanak was the first Guru and appointed a disciple as successor. Guru Gobind Singh was the final Guru in human form. Before his death, Guru Gobind Singh decreed in 1708, that the Gurū Granth Sāhib would be the final and perpetual Guru of the Sikhs. 
Guru Nanak stated that his Guru is God who is the same from the beginning of time to the end of time.  Nanak claimed to be God's mouthpiece, God's slave and servant, but maintained that he was only a guide and teacher.   Nanak stated that the human Guru is mortal, who is to be respected and loved but not worshipped.  When Guru, or SatGuru (The true Guru) is used in Gurbani it is often referring to the highest expression of truthfulness – God. 
Guru Angad succeeded Guru Nanak. Later, an important phase in the development of Sikhism came with the third successor, Guru Amar Das. Guru Nanak's teachings emphasised the pursuit of salvation; Guru Amar Das began building a cohesive community of followers with initiatives such as sanctioning distinctive ceremonies for birth, marriage, and death. Amar Das also established the manji (comparable to a diocese) system of clerical supervision. 
Guru Amar Das's successor and son-in-law Guru Ram Das founded the city of Amritsar, which is home of the Harimandir Sahib and regarded widely as the holiest city for all Sikhs. Guru Arjan was arrested by Mughal authorities who were suspicious and hostile to the religious order he was developing.  His persecution and death inspired his successors to promote a military and political organization of Sikh communities to defend themselves against the attacks of Mughal forces.
The Sikh Gurus established a mechanism which allowed the Sikh religion to react as a community to changing circumstances. The sixth Guru, Guru Hargobind, was responsible for the creation of the concept of Akal Takht (throne of the timeless one), which serves as the supreme decision-making centre of Sikhism and sits opposite the Harmandir Sahib. The Akal Takht is located in the city of Amritsar. The leader is appointed by the Shiromani Gurdwara Pabandhak Committee (SPGC). The Sarbat Ḵẖālsā (a representative portion of the Khalsa Panth) historically gathers at the Akal Takht on special festivals such as Vaisakhi or Hola Mohalla and when there is a need to discuss matters that affect the entire Sikh nation. A gurmatā (literally, Guru's intention) is an order passed by the Sarbat Ḵẖālsā in the presence of the Gurū Granth Sāhib. A gurmatā may only be passed on a subject that affects the fundamental principles of Sikh religion; it is binding upon all Sikhs.  The term hukamnāmā (literally, edict or royal order) is often used interchangeably with the term gurmatā. However, a hukamnāmā formally refers to a hymn from the Gurū Granth Sāhib which is a given order to Sikhs.
|Chronology of the ten Sikh Gurus|
There is one primary scripture for the Sikhs: the Gurū Granth Sāhib. It is sometimes synonymously referred to as the Ādi Granth.  Chronologically, however, the Ādi Granth – literally, The First Volume, refers to the version of the scripture created by Guru Arjan in 1604.  The Gurū Granth Sāhib is the final expanded version of the scripture compiled by Guru Gobind Singh.   While the Guru Granth Sahib is an unquestioned scripture in Sikhism, another important religious text, the Dasam Granth, does not enjoy universal consensus, and is considered a secondary scripture by many Sikhs. 
The Ādi Granth was compiled primarily by Bhai Gurdas under the supervision of Guru Arjan between the years 1603 and 1604.  It is written in the Gurmukhī script, which is a descendant of the Laṇḍā script used in the Punjab at that time.  The Gurmukhī script was standardised by Guru Angad, the second Guru of the Sikhs, for use in the Sikh scriptures and is thought to have been influenced by the Śāradā and Devanāgarī scripts. An authoritative scripture was created to protect the integrity of hymns and teachings of the Sikh Gurus, and thirteen Hindu and two Muslim bhagats of the Bhakti movement sant tradition in medieval India.  The thirteen Hindu bhagats whose teachings were entered into the text included Ramananda, Namdev, Pipa, Ravidas, Beni, Bhikhan, Dhanna, Jaidev, Parmanand, Sadhana, Sain, Sur, Trilochan, while the two Muslim bhagats were Kabir and Sufi saint Farid.    However the bhagats in context often spoke of transcending their religious labels, Kabir often attributed to being a Muslim states in the Adi Granth "I am not Hindu nor Muslim.  The Gurus following on this message taught that different methods of devotion are for the same infinite God. 
The Guru Granth Sahib is the holy scripture of the Sikhs, and regarded as the living Guru.
The Guru Granth started as a volume of Guru Nanak's poetic compositions. Prior to his death, he passed on his volume to Guru Angad (Guru 1539–1551). The final version of the Gurū Granth Sāhib was compiled by Guru Gobind Singh in 1678. It consists of the original Ādi Granth with the addition of Guru Tegh Bahadur's hymns. The predominant bulk of Guru Granth Sahib is compositions by seven Sikh Gurus – Guru Nanak, Guru Angad, Guru Amar Das, Guru Ram Das, Guru Arjan, Guru Teg Bahadur and Guru Gobind Singh. It also contains the traditions and teachings of thirteen Hindu Bhakti movement sants (saints) such as Ramananda, Namdev among others, and two Muslim saints namely Kabir and the Sufi Sheikh Farid.  
The text comprises 6,000 śabads (line compositions),  which are poetically rendered and set to rhythmic ancient north Indian classical music.  The bulk of the scripture is classified into thirty one rāgas, with each Granth rāga subdivided according to length and author. The hymns in the scripture are arranged primarily by the rāgas in which they are read. 
The main language used in the scripture is known as Sant Bhāṣā, a language related to both Punjabi and Hindi and used extensively across medieval northern India by proponents of popular devotional religion ( bhakti).  The text is printed in Gurumukhi script, believed to have been developed by Guru Angad,  but it shares the Indo-European roots found in numerous regional languages of India. 
The vision in the Guru Granth Sahib, states Torkel Brekke, is a society based on divine justice without oppression of any kind. 
The Granth begins with the Mūl Mantra, an iconic verse which received Guru Nanak directly from Akal Purakh (God). The traditional Mul Mantar goes from Ik Oankar until Nanak Hosee Bhee Sach.
- One God exists, truth by name, creative power, without fear, without enmity, timeless form, unborn, self-existent, by the Guru's grace. 
- ( Punjabi: ੴ ਸਤਿ ਨਾਮੁ ਕਰਤਾ ਪੁਰਖੁ ਨਿਰਭਉ ਨਿਰਵੈਰੁ ਅਕਾਲ ਮੂਰਤਿ ਅਜੂਨੀ ਸੈਭੰ ਗੁਰ ਪ੍ਰਸਾਦਿ ॥, romanized: Ika ōaṅkāra sati nāmu karatā purakhu nirabha'u niravairu akāla mūrati ajūnī saibhaṅ gura prasādi)
The Tenth Guru, Guru Gobind Singh ji, named the Sikh scripture Guru Granth Sahib as his successor, terminating the line of human Gurus and making the scripture the literal embodiment of the eternal, impersonal Guru, where Gods/Gurus word serves as the spiritual guide for Sikhs.    
- All Sikhs are commanded to take the Granth as Guru
- ( Punjabi: ਸੱਬ ਸਿੱਖਣ ਕੋ ਹੁਕਮ ਹੈ ਗੁਰੂ ਮਾਨਯੋ ਗ੍ਰੰਥ ।, romanized: Sabb sikkhaṇ kō hukam hai gurū mānyō granth)
The Guru Granth Sahib is installed in Sikh Gurdwara (temple); many Sikhs bow or prostrate before it on entering the temple. The Guru Granth Sahib is installed every morning and put to bed at night in many Gurdwaras.  The Granth is revered as eternal gurbānī and the spiritual authority. 
The copies of the Guru Granth Sahib are not regarded as material objects, but as living subjects which are alive.  According to Myrvold, the Sikh scripture is treated with respect like a living person, in a manner similar to the Gospel in early Christian worship. Old copies of the Sikh scripture are not thrown away, rather funerary services are performed. 
In India the Guru Granth Sahib is even officially recognised by the Supreme Court of India as a judicial person which can receive donations and own land.  Yet, some Sikhs also warn that, without true comprehension of the text, veneration for the text can lead to bibliolatry, with the concrete form of the teachings becoming the object of worship instead of the teachings themselves. 
The Sikh scriptures use Hindu terminology, with references to the Vedas, and the names of gods and goddesses in Hindu bhakti movement traditions, such as Vishnu, Shiva, Brahma, Parvati, Lakshmi, Saraswati, Rama, Krishna, but not to worship.  [ self-published source]  It also refers to the spiritual concepts in Hinduism ( Ishvara, Bhagavan, Brahman) and the concept of God in Islam (Allah) to assert that these are just "alternate names for the Almighty One". 
While the Guru Granth Sahib acknowledges the Vedas, Puranas and Qur'an,  it does not imply a syncretic bridge between Hinduism and Islam,  but emphasises focusing on nitnem banis like Japu (repeating mantra of the divine Name of God – WaheGuru), instead of Muslim practices such as circumcision or praying on a carpet, or Hindu rituals such as wearing thread or praying in a river. 
The Dasam Granth is a scripture of Sikhs which contains texts attributed to the Guru Gobind Singh. The Dasam Granth is important to a great number of Sikhs, however it does not have the same authority as the Guru Granth Sahib. Some compositions of the Dasam Granth like Jaap Sahib, ( Amrit Savaiye), and Benti Chaupai are part of the daily prayers ( Nitnem) for Sikhs.  The Dasam Granth is largely versions of Hindu mythology from the Puranas, secular stories from a variety of sources called Charitro Pakhyan – tales to protect careless men from perils of lust.  
Five versions of Dasam Granth exist, and the authenticity of the Dasam Granth has in modern times become one of the most debated topics within Sikhism. The text played a significant role in Sikh history, but in modern times parts of the text have seen antipathy and discussion among Sikhs. 
The Janamsākhīs (literally birth stories), are writings which profess to be biographies of Guru Nanak. Although not scripture in the strictest sense, they provide a hagiographic look at Guru Nanak's life and the early start of Sikhism. There are several – often contradictory and sometimes unreliable – Janamsākhīs and they are not held in the same regard as other sources of scriptural knowledge.
Observant Sikhs adhere to long-standing practices and traditions to strengthen and express their faith. The daily recitation of the divine name of God VaheGuru and from memory of specific passages from the Gurū Granth Sāhib, like the Japu (or Japjī, literally chant) hymns is recommended immediately after rising and bathing. Baptized Sikhs recite the five morning prayers, the evening and night prayer. Family customs include both reading passages from the scripture and attending the gurdwara (also gurduārā, meaning the doorway to God; sometimes transliterated as Gurudwara). There are many gurdwaras prominently constructed and maintained across India, as well as in almost every nation where Sikhs reside. Gurdwaras are open to all, regardless of religion, background, caste, or race.
Worship in a gurdwara consists chiefly of singing of passages from the scripture. Sikhs will commonly enter the gurdwara, touch the ground before the holy scripture with their foreheads. The recitation of the eighteenth century ardās is also customary for attending Sikhs. The ardās recalls past sufferings and glories of the community, invoking divine grace for all humanity. 
The gurdwara is also the location for the historic Sikh practice of " Langar" or the community meal. All gurdwaras are open to anyone of any faith for a free meal, always vegetarian.  People eat together, and the kitchen is maintained and serviced by Sikh community volunteers. 
Vaisakhi is one of the most important festivals of Sikhs, while other significant festivals commemorate the birth, lives of the Gurus and Sikh martyrs. Historically, these festivals have been based on the moon calendar Bikrami calendar.  In 2003, the SGPC, the Sikh organisation in charge of upkeep of the historical gurdwaras of Punjab, adopted Nanakshahi calendar.  The new calendar is highly controversial among Sikhs and is not universally accepted. Sikh festivals include the following:
Vaisakhi which includes Parades and Nagar Kirtan occurs on 13 April or 14 April. Sikhs celebrate it because on this day which fell on 30 March 1699, the tenth Guru, Gobind Singh, inaugurated the
Khalsa, the 11th body of Guru Granth Sahib and leader of Sikhs till eternity.
- Nagar Kirtan involves the processional singing of holy hymns throughout a community. While practiced at any time, it is customary in the month of Visakhi (or Vaisakhi). Traditionally, the procession is led by the saffron-robed Panj Piare (the five beloved of the Guru), who are followed by the Guru Granth Sahib, the holy Sikh scripture, which is placed on a float.
- Band Chor Diwas has been another important Sikh festival in its history.  In recent years, instead of Diwali, the post-2003 calendar released by SGPC has named it the Bandi Chhor divas.  Sikhs celebrate Guru Hargobind's release from the Gwalior Fort, with several innocent Raja kings who were also imprisoned by Mughal Emperor Jahangir in 1619. This day continues to be commemorated on the same day of Hindu festival of Diwali, with lights, fireworks and festivities.
- Hola Mohalla is a tradition started by Guru Gobind Singh. It starts the day after Sikhs celebrate Holi,  sometimes referred to as Hola.  Guru Gobind Singh modified Holi with a three-day Hola Mohalla extension festival of martial arts. The extension started the day after the Holi festival in Anandpur Sahib, where Sikh soldiers would train in mock battles, compete in horsemanship, athletics, archery and military exercises.  
- Gurpurbs are celebrations or commemorations based on the lives of the Sikh Gurus. They tend to be either birthdays or celebrations of Sikh martyrdom. All ten Gurus have Gurpurbs on the Nanakshahi calendar, but it is Guru Nanak and Guru Gobind Singh who have a gurpurb that is widely celebrated in Gurdwaras and Sikh homes. The martyrdoms are also known as a Shaheedi Gurpurbs, which mark the martyrdom anniversary of Guru Arjan and Guru Tegh Bahadur.
Khalsa Sikhs have also supported and helped develop major pilgrimage traditions to sacred sites such as Harmandir Sahib, Anandpur Sahib, Fatehgarh Sahib, Patna Sahib, Hazur Nanded Sahib, Hemkund Sahib and others.  Sikh pilgrims and Sikhs of other sects customarily consider these as holy and a part of their Tirath.  The Hola Mohalla around the festival of Holi, for example, is a ceremonial and customary gathering every year in Anandpur Sahib attracting over 100,000 Sikhs.   Major Sikh temples feature a sarovar where some Sikhs take a customary dip. Some take home the sacred water of the tank particularly for sick friends and relatives,   believing that the waters of such sacred sites have restorative powers and the ability to purify one's karma.  [ix]  The various Gurus of Sikhism have had different approach to pilgrimage. 
Upon a child's birth, the Guru Granth Sahib is opened at a random point and the child is named using the first letter on the top left hand corner of the left page. All boys are given the last name Singh, and all girls are given the last name Kaur (this was once a title which was conferred on an individual upon joining the Khalsa). 
The Sikh marriage ritual includes the anand kāraj ceremony.   The marriage ceremony is performed in front of the Guru Granth Sahib by a baptized Khalsa, Granthi of the Gurdwara.   The tradition of circling the Guru Granth Sahib and Anand Karaj among Khalsa is practised since the fourth Guru, Guru Ram Das. Its official recognition and adoption came in 1909, during the Singh Sabha Movement. 
Upon death, the body of a Sikh is usually cremated. If this is not possible, any respectful means of disposing the body may be employed. The kīrtan sōhilā and ardās prayers are performed during the funeral ceremony (known as antim sanskār). 
Khalsa (meaning "pure and sovereign") is the collective name given by Guru Gobind Singh to those Sikhs who have been fully initiated by taking part in a ceremony called ammrit sañcār (nectar ceremony).  During this ceremony, sweetened water is stirred with a double-edged sword while liturgical prayers are sung; it is offered to the initiating Sikh, who ritually drinks it.  Many Sikhs are not formally and fully initiated, as they do not undergo this ceremony, but do adhere to some components of Sikhism and identify as Sikhs. The initiated Sikh, who is believed to be reborn, is referred to as Amritdhari or Khalsa Sikh, while those who are not initiated or baptised are referred to as Kesdhari or Sahajdhari Sikhs.  
The first time that this ceremony took place was on Vaisakhi, which fell on 30 March 1699 at Anandpur Sahib in Punjab.  It was on that occasion that Gobind Singh baptised the Pañj Piārē – the five beloved ones, who in turn baptised Guru Gobind Singh himself. To males who initiated, the last name Singh, meaning "lion", was given, while the last name Kaur, meaning "princess", was given to baptised Sikh females. 
Baptised Sikhs wear five items, called the Five Ks (in Punjabi known as pañj kakkē or pañj kakār), at all times. The five items are: kēs (uncut hair), kaṅghā (small wooden comb), kaṛā (circular steel or iron bracelet), kirpān (sword/dagger), and kacchera (special undergarment).  The Five Ks have both practical and symbolic purposes. 
Guru Nanak (1469–1539), the founder of Sikhism, was born in the village of Rāi Bhōi dī Talwandī, now called Nankana Sahib (in present-day Pakistan).  His parents were Punjabi Khatri Hindus.   According to the hagiography Puratan Janamsakhi composed more than two centuries after his death and probably based on oral tradition,  Nanak as a boy was fascinated by religion and spiritual matters, spending time with wandering ascetics and holy men.  His friend was Mardana, a Muslim. Together they would sing devotional songs all night in front of the public, and bathe in the river in the morning. One day, at the usual bath, Nanak went missing and his family feared he had drowned. Three days later he returned home, and declared: "There is no Hindu, there is no Muslim" ("nā kōi hindū nā kōi musalmān"). Thereafter, Nanak started preaching his ideas that form the tenets of Sikhism. In 1526, Guru Nanak at age 50, started a small commune in Kartarpur and his disciples came to be known as Sikhs.  Although the exact account of his itinerary is disputed, hagiographic accounts state he made five major journeys, spanning thousands of miles, the first tour being east towards Bengal and Assam, the second south towards Andhra and Tamil Nadu, the third north to Kashmir, Ladakh, and Mount Sumeru  in Tibet, and the fourth to Baghdad.  In his last and final tour, he returned to the banks of the Ravi River to end his days. 
There are two competing theories on Guru Nanak's teachings.  One, according to Cole and Sambhi, is based on hagiographical Janamsakhis,  and states that Nanak's teachings and Sikhism were a revelation from God, and not a social protest movement nor any attempt to reconcile Hinduism and Islam in the 15th century.  The other states, Nanak was a Guru. According to Singha, "Sikhism does not subscribe to the theory of incarnation or the concept of prophethood. But it has a pivotal concept of Guru. He is not an incarnation of God, not even a prophet. He is an illumined soul."  The hagiographical Janamsakhis were not written by Nanak, but by later followers without regard for historical accuracy, and contain numerous legends and myths created to show respect for Nanak.  The term revelation, clarify Cole and Sambhi, in Sikhism is not limited to the teachings of Nanak, they include all Sikh Gurus, as well as the words of past, present and future men and women, who possess divine knowledge intuitively through meditation. The Sikh revelations include the words of non-Sikh bhagats, some who lived and died before the birth of Nanak, and whose teachings are part of the Sikh scriptures.  The Adi Granth and successive Sikh Gurus repeatedly emphasised, states Mandair, that Sikhism is "not about hearing voices from God, but it is about changing the nature of the human mind, and anyone can achieve direct experience and spiritual perfection at any time". 
The roots of the Sikh tradition are, states Louis Fenech, perhaps in the Sant-tradition of India whose ideology grew to become the Bhakti tradition. [vii] Furthermore, adds Fenech, "Indic mythology permeates the Sikh sacred canon, the Guru Granth Sahib and the secondary canon, the Dasam Granth and adds delicate nuance and substance to the sacred symbolic universe of the Sikhs of today and of their past ancestors". 
The development of Sikhism was influenced by the Bhakti movement; [vi] [vii] [viii] and Vaishnawa Hinduism.  however, Sikhism was not simply an extension of the Bhakti movement.   Sikhism developed while the region was being ruled by the Mughal Empire. Two of the Sikh Gurus – Guru Arjan and Guru Tegh Bahadur, after they refused to convert to Islam, were tortured and executed by the Mughal rulers.   The Islamic era persecution of Sikhs triggered the founding of the Khalsa, as an order for freedom of conscience and religion.    A Sikh is expected to embody the qualities of a "Sant-Sipāhī" – a saint-soldier.  
In 1539, Guru Nanak chose his disciple Lahiṇā as a successor to the Guruship rather than either of his sons. Lahiṇā was named Guru Angad and became the second Guru of the Sikhs.   Nanak conferred his choice at the town of Kartarpur on the banks of the river Ravi. Sri Chand, Guru Nanak's son was also a religious man, and continued his own commune of Sikhs. His followers came to be known as the Udasi Sikhs, the first parallel sect of Sikhism that formed in Sikh history.  The Udasis believe that the Guruship should have gone to Sri Chand, since he was a man of pious habits in addition to being Nanak's son. 
Guru Angad, before joining Guru Nanak's commune, worked as a pujari (priest) and religious teacher centered around Hindu goddess Durga.   On Nanak's advice, Guru Angad moved from Kartarpur to Khadur, where his wife Khivi and children were living, until he was able to bridge the divide between his followers and the Udasis. Guru Angad continued the work started by Guru Nanak and is widely credited for standardising the Gurmukhī script as used in the sacred scripture of the Sikhs. 
Guru Amar Das became the third Sikh Guru in 1552 at the age of 73. He adhered to the Vaishnavism tradition of Hinduism for much of his life, before joining the commune of Guru Angad.   Goindval became an important centre for Sikhism during the Guruship of Guru Amar Das. He was a reformer, and discouraged veiling of women's faces (a Muslim custom) as well as sati (a Hindu custom).   He encouraged the Kshatriya people to fight in order to protect people and for the sake of justice, stating this is Dharma.  Guru Amar Das started the tradition of appointing manji (zones of religious administration with an appointed chief called sangatias),  introduced the dasvandh ("the tenth" of income) system of revenue collection in the name of Guru and as pooled community religious resource,  and the famed langar tradition of Sikhism where anyone, without discrimination of any kind, could get a free meal in a communal seating. The collection of revenue from Sikhs through regional appointees helped Sikhism grow.  
Guru Amar Das named his disciple and son-in-law Jēṭhā as the next Guru, who came to be known as Guru Ram Das. The new Guru faced hostilities from the sons of Guru Amar Das and therefore shifted his official base to lands identified by Guru Amar Das as Guru-ka-Chak.  He moved his commune of Sikhs there and the place then was called Ramdaspur, after him. This city grew and later became Amritsar – the holiest city of Sikhism.  Guru Ram Das expanded the manji organization for clerical appointments in Sikh temples, and for revenue collections to theologically and economically support the Sikh movement. 
In 1581, Guru Arjan – youngest son of Guru Ram Das, became the fifth Guru of the Sikhs. The choice of successor, as throughout most of the history of Sikh Guru successions, led to disputes and internal divisions among the Sikhs.  The elder son of Guru Ram Das named Prithi Chand is remembered in the Sikh tradition as vehemently opposing Guru Arjan, creating a faction Sikh community which the Sikhs following Guru Arjan called as Minas (literally, "scoundrels").  
Guru Arjan is remembered in the Sikh for many things. He built the first Harimandir Sahib (later to become the Golden Temple). He was a poet and created the first edition of Sikh sacred text known as the Ādi Granth (literally the first book) and included the writings of the first five Gurus and other enlightened 13 Hindu and 2 Muslim Sufi saints. In 1606, he was tortured and killed by the Mughal emperor Jahangir,  for refusing to convert to Islam.    His martyrdom is considered a watershed event in the history of Sikhism.  
After the martyrdom of Guru Arjan, his son Guru Hargobind at age eleven became the sixth Guru of the Sikhs and Sikhism dramatically evolved to become a political movement in addition to being religious.  Guru Hargobind carried two swords, calling one spiritual and the other for temporal purpose (known as mīrī and pīrī in Sikhism). [ self-published source] According to the Sikh tradition, Guru Arjan asked his son Hargobind to start a military tradition to protect the Sikh people and always keep himself surrounded by armed Sikhs. The building of an armed Sikh militia began with Guru Hargobind.  Guru Hargobind was soon arrested by the Mughals and kept in jail in Gwalior. It is unclear how many years he served in prison, with different texts stating it to be between 2 and 12 years.  He married three women, built a fort to defend Ramdaspur and created a formal court called Akal Takht, now the highest Khalsa Sikh religious authority. 
In 1644, Guru Hargobind named his grandson Har Rai as the Guru. The Mughal Emperor Shah Jahan attempted political means to undermine the Sikh tradition, by dividing and influencing the succession.  The Mughal ruler gave land grants to Dhir Mal, a grandson of Guru Hargobind living in Kartarpur, and attempted to encourage Sikhs to recognise Dhir Mal as the rightful successor to Guru Hargobind.  Dhir Mal issued statements in favour of the Mughal state, and critical of his grandfather Guru Arjan. Guru Hargobind rejected Dhir Mal, the later refused to give up the original version of the Adi Granth he had, and the Sikh community was divided. 
Guru Har Rai is famed to have met Dara Shikoh during a time Dara Shikoh and his younger brother Aurangzeb were in a bitter succession fight. Aurangzeb summoned Guru Har Rai, who refused to go and sent his elder son Ram Rai instead.  The emperor found a verse in the Sikh scripture insulting to Muslims, and Ram Rai agreed it was a mistake then changed it. Ram Rai thus pleased Aurangzeb, but displeased Guru Har Rai who excommunicated his elder son. He nominated his younger son Guru Har Krishan to succeed him in 1661. Aurangzeb responded by granting Ram Rai a jagir (land grant). Ram Rai founded a town there and enjoyed Aurangzeb's patronage, the town came to be known as Dehradun, after Dehra referring to Ram Rai's shrine. Sikhs who followed Ram Rai came to be known as Ramraiya Sikhs.    Guru Har Krishan became the eighth Guru at the age of five, and died of smallpox before reaching the age of eight. No hymns composed by these three Gurus are included in the Guru Granth Sahib. 
Guru Tegh Bahadur, the uncle of Guru Har Krishan, became Guru in 1665. Tegh Bahadur resisted the forced conversions of Kashmiri Pandits  and non-Muslims  to Islam, and was publicly beheaded in 1675 on the orders of Mughal emperor Aurangzeb in Delhi for refusing to convert to Islam.   His beheading traumatized the Sikhs. His body was cremated in Delhi, the head was carried secretively by Sikhs and cremated in Anandpur. He was succeeded by his son, Gobind Rai who militarised his followers by creating the Khalsa in 1699, and baptising the Pañj Piārē.  From then on, he was known as Guru Gobind Singh, and Sikh identity was redefined into a political force resisting religious persecution. 
Some bodyguards of Maharaja Ranjit Singh at the Sikh capital, Lahore, Punjab.
Guru Gobind Singh inaugurated the Khalsa (the collective body of all initiated Sikhs) as the Sikh temporal authority in the year 1699. It created a community that combines its spiritual purpose and goals with political and military duties.    Shortly before his death, Guru Gobind Singh proclaimed the Gurū Granth Sāhib (the Sikh Holy Scripture) to be the ultimate spiritual authority for the Sikhs. 
The Sikh Khalsa's rise to power began in the 17th century during a time of growing militancy against Mughal rule. The creation of a Sikh Empire began when Guru Gobind Singh sent a Sikh general, Banda Singh Bahadur, to fight the Mughal rulers of India [ self-published source] and those who had committed atrocities against Pir Buddhu Shah. Banda Singh advanced his army towards the main Muslim Mughal city of Sirhind and, following the instructions of the Guru, punished all the culprits. Soon after the invasion of Sirhind, while resting in his chamber after the Rehras prayer Guru Gobind Singh was stabbed by a Pathan assassin hired by Mughals. Gobind Singh killed the attacker with his sword. Though a European surgeon stitched the Guru's wound, the wound re-opened as the Guru tugged at a hard strong bow after a few days, causing profuse bleeding that led to Gobind Singh's death.
After the Guru's death, Baba Banda Singh Bahadur became the commander-in-chief of the Khalsa.  He organised the civilian rebellion and abolished or halted the Zamindari system in time he was active and gave the farmers proprietorship of their own land.  Banda Singh was executed by the emperor Farrukh Siyar after refusing the offer of a pardon if he converted to Islam. The confederacy of Sikh warrior bands known as misls emerged, but these fought between themselves. Ranjit Singh achieved a series of military victories and created a Sikh Empire in 1799.
The Sikh empire had its capital in Lahore, spread over almost 200,000 square miles (520,000 square kilometres) comprising what is now northwestern Indian subcontinent. The Sikh Empire entered into a treaty with the colonial British powers, with each side recognizing Sutlej River as the line of control and agreeing not to invade the other side.  Ranjit Singh's most lasting legacy was the restoration and expansion of the Harmandir Sahib, most revered Gurudwara of the Sikhs, with marble and gold, from which the popular name of the " Golden Temple" is derived.  After the death of Ranjit Singh in 1839, the Sikh Empire fell into disorder. Ranjit Singh had failed to establish a lasting structure for Sikh government or stable succession, and the Sikh Empire rapidly declined after his death. Factions divided the Sikhs, and led to Anglo-Sikh wars. The British easily defeated the confused and demoralised Khalsa forces, then disbanded them into destitution.  The youngest son of Ranjit Singh named Duleep Singh ultimately succeeded, but he was arrested and exiled after the defeat of Sikh Khalsa. 
The Singh Sabha movement, a movement to revitalize Sikhism, also saw the resurgence of the Khalsa after their defeat by the British in the Anglo-Sikh wars,  and the subsequent decline and corruption of Sikh institutions during colonial rule, and the proselytization of other faith groups in the Punjab.   It was started in the 1870s, and after a period of interfactional rivalry, united under the Tat Khalsa to reinvigorate Sikh practice and institutions. 
The last Maharaja of the Sikh Empire Duleep Singh converted to Christianity in 1853, a controversial but influential event in Sikh history. Along with his conversion, and after Sikh Empire had been dissolved and the region made a part of the colonial British Empire, proselytising activities of Christians, Brahmo Samajis, Arya Samaj, Muslim Anjuman-i-Islamia and Ahmadiyah sought to convert the Sikhs in northwestern Indian subcontinent into their respective faiths.   These developments launched the Singh Sabha Movement.  
The first meeting of the movement was in the Golden Temple, Amritsar in 1873, and it was largely launched by the Sanatan Sikhs, Gianis, priests, and granthis.  Shortly thereafter, Nihang Sikhs began influencing the movement, followed by a sustained campaign by the Tat Khalsa, which had quickly gained dominance by the early 1880s.   The movement became a struggle between Sanatan Sikhs and Tat Khalsa in defining and interpreting Sikhism.   
Sanatan Sikhs led by Khem Singh Bedi – who claimed to be a direct descendant of Guru Nanak, Avtar Singh Vahiria and others supported a more inclusive approach which considered Sikhism as a reformed tradition of Hinduism, while Tat Khalsa campaigned for an exclusive approach to the Sikh identity, disagreeing with Sanatan Sikhs and seeking to modernize Sikhism.    The Sikh Sabha movement expanded in north and northwest Indian subcontinent, leading to more than 100 Singh Sabhas.   By the early decades of the 20th century, the influence of Tat Khalsa increased in interpreting the nature of Sikhism and their control over the Sikh Gurdwaras.    The Tat Khalsa banished Brahmanical practices including the use of the yagna fire,   replaced by the Anand Karaj marriage ceremony in accordance with Sikh scripture, and the idols and the images of Sikh Gurus from the Golden Temple in 1905, traditions which had taken root during the administration of the mahants during the 1800s.  They undertook a sustained campaign to standardize how Sikh Gurdwaras looked and ran, while looking to Sikh scriptures and the early Sikh tradition  to purify the Sikh identity. 
The spiritual successors of the Singh Sabha include the Akali movement of the 1920s, as well as the modern-day Shiromani Gurdwara Parbandhak Committee ( SGPC), a gurdwara administration body, and the Akali Dal political party. 
Sikhs participated and contributed to the decades-long Indian independence movement from the colonial rule in the first half of the 20th century. Ultimately when the British Empire recognized independent India, the land was partitioned into Hindu majority India and Muslim majority Pakistan (East and West) in 1947. This event, states Banga, was a watershed event in Sikh history.   The Sikhs had historically lived in northwestern region of Indian subcontinent on both sides of the partition line (" Radcliffe Line"). According to Banga and other scholars, the Sikhs had strongly opposed the Muslim League demands and saw it as "perpetuation of Muslim domination" and anti-Sikh policies in what just a hundred years before was a part of the Sikh Empire. As such, Sikh organizations, including the Chief Khalsa Dewan and Shiromani Akali Dal led by Master Tara Singh, condemned the Lahore Resolution and the movement to create Pakistan, viewing it as inviting possible persecution; the Sikhs largely thus strongly opposed the partition of India.  During the discussions with the colonial authorities, Tara Singh emerged as an important leader who campaigned to prevent the partition of colonial India and for the recognition of Sikhs as the third community.  In 1940, a few Sikhs such as the victims of Komagata Maru in Canada proposed the idea of Khalistan as a buffer state between Pakistan and India.  These leaders, however, were largely ignored.   Many other Sikh leaders supported the partition along religious and demographic lines. 
When partition was announced, the newly created line divided the Sikh population into two halves. The Sikhs suffered organized violence and riots against them in West Pakistan, and Sikhs moved en masse to the Indian side leaving behind their property and the sacred places of Sikhism. This reprisals on Sikhs were not one sided, because as Sikhs entered the Indian side, the Muslims in East Punjab experienced reprisals and they moved to West Pakistan.   Before the partition, Sikhs constituted about 15% of the population in West Punjab that became a part of Pakistan, the majority being Muslims (55%). The Sikhs were the economic elite and wealthiest in West Punjab, with them having the largest representation in West Punjab's aristocracy, nearly 700 Gurdwaras and 400 educational institutions that served the interests of the Sikhs.  Prior to the partition, there were a series of disputes between the majority Muslims and minority Sikhs, such as on the matters of jhatka versus halal meat, the disputed ownership of Gurdwara Sahidganj in Lahore which Muslims sought as a mosque and Sikhs as a Gurdwara, and the insistence of the provincial Muslim government in switching from Indian Gurmukhi script to Arabic-Persian Nastaliq script in schools.  During and after the Simla Conference in June 1945, headed by Lord Wavell, the Sikh leaders initially expressed their desire to be recognized as the third party, but ultimately relegated their demands and sought a United India where Sikhs, Hindus and Muslims would live together, under a Swiss style constitution. The Muslim League rejected this approach, demanding that entire Punjab should be granted to Pakistan.  The Sikh leaders then sought the partition instead, and Congress Working Committee passed a resolution in support of partitioning Punjab and Bengal. 
Between March and August 1947, a series of riots, arson, plunder of Sikh property, assassination of Sikh leaders, and killings in Jhelum districts, Rawalpindi, Attock and other places made Tara Singh call the situation in Punjab as "civil war", while Lord Mountbatten stated "civil war preparations were going on". The riots had triggered the early waves of migration in April, with some 20,000 people leaving northwest Punjab and moving to Patiala.   In Rawalpindi, 40,000 people became homeless. The Sikh leaders made desperate petitions, but all religious communities were suffering in the political turmoil. Sikhs, states Banga, were "only 4 million out of a total of 28 million in Punjab, and 6 million out of nearly 400 million in India; they did not constitute the majority, not even in a single district".  
When the partition line was formally announced in August 1947, the violence was unprecedented, with Sikhs being one of the most affected religious community both in terms of deaths, as well as property loss, injury, trauma and disruption.   Sikhs and Muslims were both victims and perpetrators of retaliatory violence against each other. Estimates range between 200,000 and 2 million deaths of Sikhs, Hindus and Muslims.   There were numerous rapes of and mass suicides by Sikh women, they being taken captives, their rescues and above all a mass exodus of Sikhs from newly created Pakistan into newly created India. The partition created the "largest foot convoy of refugees recorded in [human] history, stretching over 100 kilometer long", states Banga, with nearly 300,000 people consisting of mostly "distraught, suffering, injured and angry Sikhs". Sikh and Hindu refugees from Pakistan flooded into India, Muslim refugees from India flooded into Pakistan, each into their new homeland.  
The early 1980s witnessed some Sikh groups seeking an independent nation named Khalistan carved out from India and Pakistan. The Golden Temple and Akal Takht were occupied by various militant groups in 1982. These included the Dharam Yudh Morcha led by Jarnail Singh Bhindranwale, the Babbar Khalsa, the AISSF and the National Council of Khalistan.  Between 1982 and 1983, there were Anandpur Resolution demand-related terrorist attacks against civilians in parts of India.  By late 1983, the Bhindranwale led group had begun to build bunkers and observations posts in and around the Golden Temple, with militants involved in weapons training.  In June 1984, the then Prime Minister of India Indira Gandhi ordered Indian Army to begin Operation Blue Star against the militants.  The fierce engagement took place in the precincts of Darbar Sahib and resulted in many deaths, including Bhindranwale, the destruction of the Sikh Reference Library, which was considered a national treasure that contained over a thousand rare manuscripts,  and destroyed Akal Takht. Numerous soldiers, civilians and militants died in the cross fire. Within days of the Operation Bluestar, some 2,000 Sikh soldiers in India mutinied and attempted to reach Amritsar to liberate the Golden Temple.  Within six months, on 31 October 1984, Indira Gandhi's Sikh bodyguards assassinated her. The assassination triggered the 1984 anti-Sikh riots.  According to Donald Horowitz, while anti-Sikh riots led to much damage and deaths, many serious provocations by militants also failed to trigger ethnic violence in many cases throughout the 1980s. The Sikhs and their neighbors, for most part, ignored attempts to provoke riots and communal strife.

Estimates state that Sikhism has some 25 million followers worldwide. [viii] But however according to rough estimates, there are around 12-15 crore Nanak Naam Lewas people across the world who also believe in 10 Sikh Gurus and Shri Guru Granth Sahib.  According to Pew Research, a religion demographics and research group in Washington DC, "more than nine-in-ten Sikhs are in India, but there are also sizable Sikh communities in the United States, the United Kingdom and Canada."  Within India, the Sikh population is found in every state and union territory, but it is predominantly found in the northwestern and northern states. Only in the state of Punjab, Sikhs constitute a majority (58% of the total, per 2011 census).  The states and union territories of India where Sikhs constitute more than 1.5% of its population are Punjab, Chandigarh, Haryana, Delhi, Uttarakhand and Jammu & Kashmir.  Forming 4.7% of the total population, the western Canadian province of British Columbia is home to over 200,000 Sikhs and is the only province or state in the world outside India with Sikhism as the second most followed religion among the population.  
Sikhism was founded in northwestern region of the Indian subcontinent in what is now Pakistan. Some of the Gurus were born near Lahore and in other parts of Pakistan. Prior to 1947, in British India, millions of Sikhs lived in what later became Pakistan. During the partition, Sikhs and Hindus left the newly created Muslim-majority Pakistan and mostly moved to Hindu-majority India - with some moving to Muslim-majority Afghanistan ), - while Muslims in India left and moved to Pakistan.   According to 2017 news reports, only about 20,000 Sikhs remain in Pakistan and their population is dwindling (0.01% of its estimated 200 million population). The Sikhs in Pakistan, like others in the region, have been "rocked by an Islamist insurgency for more than a decade".  
Sikh sects are sub-traditions within Sikhism that believe in an alternate lineage of Gurus, or have a different interpretation of the Sikh scriptures, or believe in following a living Guru, or other concepts that differ from the orthodox Khalsa Sikhs.   The major historic sects of Sikhism, states Harjot Oberoi, have included Udasi, Nirmala, Nanakpanthi, Khalsa, Sahajdhari, Namdhari Kuka, Nirankari and Sarvaria. 
The early Sikh sects were Udasis and Minas founded by Sri Chand – the elder son of Guru Nanak, and Prithi Chand – the elder son of Guru Ram Das respectively, in parallel to the official succession of the Sikh Gurus. Later on Ramraiya sect grew in Dehradun with the patronage of Aurangzeb.  Many splintered Sikh communities formed during the Mughal Empire era. Some of these sects were financially and administratively supported by the Mughal rulers in the hopes of gaining a more favorable and compliant citizenry.  
After the collapse of Mughal Empire, and particularly during the rule of Ranjit Singh, Udasi Sikhs protected Sikh shrines, preserved the Sikh scripture and rebuilt those that were desecrated or destroyed during the Muslim–Sikh wars. However, Udasi Sikhs kept idols and images inside these Sikh temples.   In the 19th century, Namdharis and Nirankaris sects were formed in Sikhism, seeking to reform and return to what each believed was the pure form of Sikhism.   
All these sects differ from Khalsa orthodox Sikhs in their beliefs and practices, such as continuing to solemnize their weddings around fire and being strictly vegetarian.   Many accept the concept of living Gurus such as Guru Baba Dyal Singh. The Nirankari sect though unorthodox was influential in shaping the views of Tat Khalsa and the contemporary era Sikh beliefs and practices.   Another significant Sikh sect of the 19th century was the Radhasoami movement in Punjab led by Baba Shiv Dyal.  Other contemporary era Sikhs sects include the 3HO, formed in 1971, which exists outside India, particularly in North America and Europe.   
According to Surinder Jodhka, the state of Punjab with a Sikh majority has the "largest proportion of scheduled caste population in India". Although decried by Sikhism, Sikhs have practiced a caste system. The system, along with untouchability, has been more common in rural parts of Punjab. The landowning dominant Sikh castes, states Jodhka, "have not shed all their prejudices against the lower castes or dalits; while dalits would be allowed entry into the village gurdwaras they would not be permitted to cook or serve langar." The Sikh dalits of Punjab have tried to build their own gurdwara, other local level institutions and sought better material circumstances and dignity. According to Jodhka, due to economic mobility in contemporary Punjab, castes no longer mean an inherited occupation nor are work relations tied to a single location.  In 1953, the government of India acceded to the demands of the Sikh leader, Master Tara Singh, to include Sikh dalit castes in the list of scheduled castes.  In the Shiromani Gurdwara Prabandhak Committee, 20 of the 140 seats are reserved for low-caste Sikhs. 
Over 60% of Sikhs belong to the Jat caste, which is an agrarian caste. Despite being very small in numbers, the Kshatriya Khatri and Arora castes wield considerable influence within the Sikh community. Other common Sikh castes include Sainis, Ramgarhias (artisans), Ahluwalias (formerly brewers), Kambojs (rural caste), Labanas, Kumhars and the two Dalit castes, known in Sikh terminology as the Mazhabis (the Chuhras) and the Ravidasias (the Chamars). 
Sikhism is the fourth-largest amongst the medium-sized world religions, and one of the youngest.    Worldwide, there are 25.8 million Sikhs, which makes up 0.39% of the world's population. Approximately 75% of Sikhs live in Punjab, where they constitute over 50% of the state's population. Large communities of Sikhs migrate to the neighboring states such as Indian State of Haryana which is home to the second largest Sikh population in India with 1.1 million Sikhs as per 2001 census, and large immigrant communities of Sikhs can be found across India. However, Sikhs only comprise about 2% of the Indian population. 
Sikh migration to Canada began in the 19th century and led to the creation of significant Sikh communities, predominantly in South Vancouver, British Columbia, Surrey, British Columbia, and Brampton, Ontario. Today temples, newspapers, radio stations, and markets cater to these large, multi-generational Indo-Canadian groups. Sikh festivals such as Vaisakhi and Bandi Chhor are celebrated in those Canadian cities by the largest groups of followers in the world outside the Punjab.
Sikhs also migrated to East Africa, West Africa, the Middle East, Southeast Asia, the United Kingdom, the United States, and Australia. These communities developed as Sikhs migrated out of Punjab to fill in gaps in imperial labour markets.  In the early twentieth century a significant community began to take shape on the west coast of the United States. Smaller populations of Sikhs are found within many countries in Western Europe, Mauritius, Malaysia, Philippines, Fiji, Nepal, China, Pakistan, Afghanistan, Iran, Singapore, United States, and many other countries.
Some major prohibitions include:
- Haircuts: Cutting or removing hair from any body part is strictly forbidden including shaving or trimming facial and nostril hairs for both Amritdhari (formally baptized) and Keshdhari (non-baptized and practicing) Sikhs.
- Intoxication: Consumption of drugs, alcohol, tobacco and other intoxicants is not allowed for Amritdhari Sikhs and Keshdhari Sikhs. Drugs and tobacco are forbidden for all.    Cannabis is generally prohibited, but ritually consumed in edible form by some Sikhs.  
- Gambling: Gambling, also called Jooa in traditional Indian languages, be it in any form like lottery, roulette, poker, american bingo or british bingo, is prohibited in some codes of conduct, such as the Sikh Rehat Maryada.
- Priestly class: Sikhism does not have priests, as they were abolished by Guru Gobind Singh (the 10th Guru of Sikhism).  The only position he left was a Granthi to look after the Guru Granth Sahib; any Sikh is free to become Granthi or read from the Guru Granth Sahib. 
- Eating meat killed in a ritualistic manner ( Kutha meat): Sikhs are strictly prohibited from eating meat killed in a ritualistic manner (such as halal or kosher, known as Kutha meat),  or any meat where langar is served.  For many Sikhs (and in some Sikh sects, e.g. Akhand Kirtani Jatha) Damdami Taksal, Nanaksar, eating any meat is believed to be forbidden, but this is not a universally held belief.  It is patit for Sikhs to eat anything which is made after the killings of animals in a ritualistic manner. 
- Having extramarital sexual relations

- The Sikh scripture contains verses which have been literally interpreted as relevant to pilgrimage and taking dips in waters for salvific value; some criticize it (AG 358, 75); others support it (AG 623–624).

The main thrust of Kabir's mission was to unite Hindus and Muslims in a common quest for god realisation. 'Hindus and Muslims have the same god,' he held. 'God is the breath of all breath . . . Look within your heart, for there you will find [god] . . . All men and women in the world are his living forms.' Although many of his sayings had a strong Hindu flavour in them—presumably because of Ramananda's influence—he made no distinction between Hinduism and Islam Similarly, though he usually referred to god as Hari or Rama, he used those words as synonyms of god, and not as the names of particular deities. 'I am not Hindu nor Muslim; Allah-Ram is the breath of my body,' he stated, and went on to declare that All that lives and dies, they are all one. The this and that haggling, is done.

The Sikh Divine comprises every imaginable theological ideal! Hindu, Buddhist, Tantric, and Islamic views that were current in medieval India come together in the wide-ranging literary spectrum of the GGS. The stereotypical oppositions between the Indic and Abrahamic worldviews of the day are transcended: "Some call it Rama, some call it Khuda; some worship it as Vishnu, some as Allah" (GGS: 885). Interestingly, even the atheistic Buddhist Nirvana is not omitted: "Itself Nirvana, It itself relishes pleasures" (GGS: 97). "God" or "gods" or "no god" alike are recognized as part of the infinite One! "Always, always you alone are the One Reality—sada sada tun eku hai" (GGS: 139). Persian terminology is used to emphasize the unity of being: "asti ek digari kui ek tui ek tui —Only the One is, there is none other; Only you, you only" (GGS: 144). Again, "hindu turk ka sahib ek—Hindus and Muslims share the One sovereign" (GGS: 1158). (The term "Turk" referred to all Muslims in this period.) Since everything is a manifestation of That One being, all the manifestations would be a part of it. No god, no body, and no thing is excluded from this all pervasive being.

No sooner was it made public than the Sikhs launched a virulent campaign against the Lahore Resolution. Pakistan was portrayed as a possible return to an unhappy past when Sikhs were persecuted and Muslims the persecutor. Public speeches by various Sikh political leaders on the subject of Pakistan invariably raised images of atrocities committed by Muslims on Sikhs and of the martyrdom of their gurus and heroes. Reactions to the Lahore Resolution were uniformly negative and Sikh leaders of all political persuasions made it clear that Pakistan would be 'wholeheartedly resisted'. The Shiromani Akali Dal, the party with a substantial following amongst the rural Sikhs, organized several well-attended conferences in Lahore to condemn the Muslim League. Master Tara Singh, leader of the Akali Dal, declared that his party would fight Pakistan 'tooth and nail'. Not be outdone, other Sikh political organizations, rival to the Akali Dal, namely the Central Khalsa Young Men Union and the moderate and loyalist Chief Khalsa Dewan, declared in equally strong language their unequivocal opposition to the Pakistan scheme.
