Abdulaziz ( Ottoman Turkish: عبد العزيز, romanized: ʿAbdü'l-ʿAzîz; Turkish: Abdülaziz; 8 February 1830 – 4 June 1876) was the sultan of the Ottoman Empire from 25 June 1861 to 30 May 1876, when he was overthrown in a government coup.  He was a son of Sultan Mahmud II and succeeded his brother Abdulmejid I in 1861. 
Born at Eyüp Palace, Constantinople ( Istanbul),   on 8 February 1830, Abdulaziz received an Ottoman education but was nevertheless an ardent admirer of the material progress that was being achieved in the West. He was the first Ottoman sultan who travelled to Western Europe, visiting a number of important European capitals including Paris, London, and Vienna in the summer of 1867.
Apart from his passion for the Ottoman Navy, which had the world's third largest fleet in 1875 (after the British and French navies), the Sultan took an interest in documenting the Ottoman Empire. He was also interested in literature and was a classical music composer. Some of his compositions, together with those of the other members of the Ottoman dynasty, have been collected in the album European Music at the Ottoman Court by the London Academy of Ottoman Court Music.  He was deposed on the grounds of having mismanaged the Ottoman economy on 30 May 1876, and was found dead six days later in mysterious circumstances.
His parents were Mahmud II and Pertevniyal Sultan,  originally named Besime, a Circassian.  In 1868 Pertevniyal was residing at Dolmabahçe Palace. That year Abdulaziz took the visiting Eugénie de Montijo, Empress of France, to see his mother. Pertevniyal considered the presence of a foreign woman within her private quarters of the seraglio to be an insult. She reportedly slapped Eugénie across the face, which almost caused an international incident.  According to another account, Pertevniyal was outraged by the forwardness of Eugénie in taking the arm of one of her sons while he gave a tour of the palace garden, and she gave the Empress a slap on the stomach as a possibly more subtly intended reminder that they were not in France. 
His paternal grandparents were Sultan Abdul Hamid I and Sultana Nakşidil Sultan. Several accounts identify his paternal grandmother with Aimée du Buc de Rivéry, a cousin of Empress Joséphine.  Pertevniyal was a sister of Khushiyar Qadin, third wife of Ibrahim Pasha of Egypt. Khushiyar and Ibrahim were the parents of Isma'il Pasha.  
Between 1861 and 1871, the Tanzimat reforms which began during the reign of his brother Abdulmejid I were continued under the leadership of his chief ministers, Mehmed Fuad Pasha and Mehmed Emin Âli Pasha. New administrative districts (vilayets) were set up in 1864 and a Council of State was established in 1868.  Public education was organized on the French model and Istanbul University was reorganised as a modern institution in 1861.  He was also integral in establishing the first Ottoman civil code.  Under his reign, Turkey's first postage stamps were issued in 1863, and the Ottoman Empire joined the Universal Postal Union in 1875 as a founding member.
Abdulaziz cultivated good relations with France and the United Kingdom. In 1867 he was the first Ottoman sultan to visit Western Europe.  His voyage in visiting order (from 21 June 1867 to 7 August 1867): Istanbul – Messina – Naples – Toulon – Marseille – Paris – Boulogne – Dover – London – Dover – Calais – Brussels – Koblenz – Vienna – Budapest – Orșova – Vidin – Ruse – Varna – Istanbul.  His trip included a visit to the Exposition Universelle (1867) in Paris and a trip to the United Kingdom, where he was made a Knight of the Garter by Queen Victoria  and shown a Royal Navy Fleet Review with Ismail Pasha. He travelled by a private rail car, which today can be found in the Rahmi M. Koç Museum in Istanbul. His fellow Knights of the Garter created in 1867 were Charles Gordon-Lennox, 6th Duke of Richmond, Charles Manners, 6th Duke of Rutland, Henry Somerset, 8th Duke of Beaufort, Prince Arthur, Duke of Connaught and Strathearn (a son of Queen Victoria), Franz Joseph I of Austria and Alexander II of Russia. Impressed by the museums in Paris (30 June – 10 July 1867),  London (12–23 July 1867)  and Vienna (28–30 July 1867)  he ordered the establishment of an Imperial Museum in Istanbul: the Istanbul Archaeology Museum.
In 1869, Abdulaziz received visits from Eugénie de Montijo, Empress consort of Napoleon III of France and other foreign monarchs on their way to the opening of the Suez Canal. The Prince of Wales, the future Edward VII, twice visited Istanbul. 
The first Ottoman railroads were opened between İzmir– Aydın and Alexandria– Cairo in 1856, during the reign of Sultan Abdulmejid I. The first large railway terminal within present-day Turkey, the Alsancak Terminal in Izmir, was opened in 1858. However, these were individual, unconnected railroads, without a railway network. Sultan Abdulaziz established the first Ottoman railway networks. On 17 April 1869, the concession for the Rumelia Railway (i.e. Balkan Railways, Rumeli (Rumelia) meaning the Balkan peninsula in Ottoman Turkish) which connected Istanbul to Vienna was awarded to Baron Maurice de Hirsch (Moritz Freiherr Hirsch auf Gereuth), a Bavaria-born banker from Belgium. The project foresaw a railway route from Istanbul via Edirne, Plovdiv and Sarajevo to the shore of the Sava River. In 1873, the first Sirkeci Terminal in Istanbul was opened. The temporary Sirkeci terminal building was later replaced with the current one which was built between 1888 and 1890 (during the reign of Abdülhamid II) and became the final destination terminus of the Orient Express. In 1871, Sultan Abdulaziz established the Anatolia Railway. Construction works of the 1,435 mm (4 ft 8+1⁄2 in) standard gauge on the Asian side of Istanbul, from Haydarpaşa to Pendik, began in 1871. The line was opened on 22 September 1872.  The railway was extended to Gebze, which opened on 1 January 1873. In August 1873 the railway reached Izmit. Another railway extension was built in 1871 to serve a populated area along Bursa and the Sea of Marmara. The Anatolia Railway was then extended to Ankara and eventually to Mesopotamia, Syria and Arabia during the reign of Sultan Abdulhamid II, with the completion of the Baghdad Railway and Hejaz Railway.
Also in 1867, Abdulaziz became the first Ottoman Sultan to formally recognize the title of Khedive (Viceroy) to be used by the Governor of the Ottoman Eyalet of Egypt and Sudan (1517–1867), which thus became the autonomous Ottoman Khedivate of Egypt and Sudan (1867–1914). Muhammad Ali Pasha and his descendants had been the governors of Ottoman Egypt and Sudan since 1805, but were willing to use the higher title of Khedive, which was unrecognized by the Ottoman government until 1867. In return, the first Khedive, Ismail Pasha, had agreed a year earlier (in 1866) to increase the annual tax revenues which Egypt and Sudan would provide for the Ottoman treasury.  Between 1854 and 1894,   the revenues from Egypt and Sudan were often declared as a surety by the Ottoman government for borrowing loans from British and French banks.  
Abdulaziz gave special emphasis on modernizing the Ottoman Navy. In 1875, the Ottoman Navy had 21 battleships and 173 warships of other types, ranking as the third largest navy in the world after the British and French navies. His passion for the Navy, ships and sea can be observed in the wall paintings and pictures of the Beylerbeyi Palace, which was constructed during his reign. However, the large budget for modernizing and expanding the Navy (combined with a severe drought in 1873 and incidents of flooding in 1874 which damaged Ottoman agriculture and reduced the government's tax revenues) contributed to the financial difficulties which caused the Porte to declare a sovereign default with the "Ramazan Kanunnamesi" on 30 October 1875. The subsequent decision to increase agricultural taxes for paying the Ottoman public debt to foreign creditors (mainly British and French banks) triggered the Great Eastern Crisis in the empire's Balkan provinces. The crisis culminated in the Russo-Turkish War (1877–78) that devastated the already struggling Ottoman economy, and the establishment of the Ottoman Public Debt Administration in 1881, during the early years of Sultan Abdulhamid II's reign. 
This financial turmoil increased the importance of Britain for the sureties regarding the Ottoman revenues from Egypt and Sudan.  Combined with the much more important Suez Canal which was opened in 1869, these sureties were influential in the British government's decision to occupy Egypt and Sudan in 1882, with the pretext of helping the Ottoman-Egyptian government to put down the ʻUrabi revolt (1879–1882). Egypt and Sudan (together with Cyprus) nominally remained Ottoman territories until 5 November 1914,  when the British Empire declared war against the Ottoman Empire during World War I. 
By 1871, both Fuad Pasha and Âli Pasha were dead.  The Second French Empire, his Western European model, had been defeated in the Franco-Prussian War. Abdulaziz turned to the Russian Empire for friendship, as unrest in the Balkan provinces continued. In 1875, the Herzegovinian rebellion was the beginning of further unrest in the Balkan provinces. In 1876, the April Uprising saw insurrection spreading among the Bulgarians. Ill feeling mounted against Russia for its encouragement of the rebellions. 
While no one event led to his being deposed, the crop failure of 1873 and his lavish expenditures on the Ottoman Navy and on new palaces which he had built, along with mounting public debt, helped to create an atmosphere conducive to his being overthrown. Abdulaziz was deposed by his ministers on 30 May 1876. 
This Death may be unbalanced towards certain viewpoints. (November 2020)
Following Sultan Abdulaziz's dethronement, he was taken into a room at Topkapi Palace. This room happened to be the same room that Sultan Selim III was murdered in. The room caused him to be concerned for his life and he subsequently requested to be moved to Beylerbeyi Palace. His request was denied for the palace was considered inconvenient for his situation and he was moved to Feriye Palace instead. He nevertheless had grown increasingly nervous and paranoid about his security. In the morning of 5 June, Abdulaziz asked for a pair of scissors to trim his beard. Shortly after this, he was found dead in a pool of blood flowing from two wounds in his arms.
Several physicians were allowed to examine his body. Among which "Dr. Marco, Nouri, A. Sotto, Physician attached to the Imperial and Royal Embassy of Austria‐Hungary; Dr. Spagnolo, Marc Markel, Jatropoulo, Abdinour, Servet, J. de Castro, A. Marroin, Julius Millingen, C. Caratheodori; E. D. Dickson, Physician of the British Embassy; Dr. O. Vitalis, Physician of the Sanitary Board; Dr. E. Spadare, J. Nouridjian, Miltiadi Bey, Mustafa, Mehmed" certified that the death had been "caused by the loss of blood produced by the wounds of the blood‐vessels at the joints of the arms" and that "the direction and nature of the wounds, together with the instrument which is said to have produced them, lead us to conclude that suicide had been committed".  One of those physicians also stated that "His skin was very pale, and entirely free from bruises, marks or spots of any kind whatever. There was no lividity of the lips indicating suffocation nor any sign of pressure having been applied to the throat".  Abdulaziz's death at was documented as a suicide.  
There are several sources claiming the death of Abdulaziz was due to an assassination. Islamic nationalist author Necip Fazıl Kısakürek claimed that it was a clandestine operation carried out by the British. 
Another similar claim is based on the book The Memoirs of Sultan Abdulhamid II. In the book, which turned out to be a fraud,   Abdulhamid II claims that Sultan Murad V had begun to show signs of paranoia, madness, and continuous fainting and vomiting until the day of his coronation, and he even threw himself into a pool yelling at his guards to protect his life. High-ranking politicians of the time were afraid the public would become outraged and revolt to bring Abdulaziz back to power. Thus, they arranged the assassination of Abdulaziz by cutting his wrists and announced that "he committed suicide".  This book of memoir was commonly referred to as a first-hand testimony of the assassination of Abdulaziz. Yet it was proven, later on, that Abdulhamid II never wrote nor dictated such a document.  
In addition to these, Abdülaziz planned to marry the Egyptian princess Tawhida Hanim, daughter of the Egyptian chedive Isma'il Pasha. His Grand Vizier, Mehmed Fuad Pasha, was opposed to marriage and wrote a note for the sultan explaining that marriage would be politically counterproductive and would give Egypt an undue advantage. However, the Grand Chamberlain, instead of handing the note to the sultan, read it to him in public, humiliating him. Although the marriage project was abandoned, Fuad was fired for the accident.
