Delaware ( // ( listen) DEL-ə-wair)  is a state in the Mid-Atlantic  region of the United States, [a] bordering Maryland to its south and west; Pennsylvania to its north; and New Jersey and the Atlantic Ocean to its east. The state takes its name from the nearby Delaware River named after Thomas West, 3rd Baron De La Warr, an English nobleman and Virginia's first colonial governor. 
Delaware occupies the northeastern portion of the Delmarva Peninsula and some islands and territory within the Delaware River. It is the second-smallest and sixth-least populous state, but also the sixth-most densely populated. Delaware's largest city is Wilmington, while the state capital is Dover, the second-largest city in the state. The state is divided into three counties, having the lowest number of any state; from north to south, they are New Castle County, Kent County, and Sussex County. While the southern two counties have historically been predominantly agricultural, New Castle is more urbanized. In a similar vein to Maryland, Delaware's geography, culture, and history combine elements of the Mid-Atlantic, Northeastern, and Southern regions of the country.
Before its coastline was explored by Europeans in the 16th century, Delaware was inhabited by several groups of Native Americans, including the Lenape in the north and Nanticoke in the south. It was initially colonized by Dutch traders at Zwaanendael, near the present town of Lewes, in 1631. Delaware was one of the 13 colonies participating in the American Revolution. On December 7, 1787, Delaware became the first state to ratify the Constitution of the United States, and has since been known as The First State.  Since the turn of the 20th century, Delaware is also a de facto onshore corporate haven, in which by virtue of its corporate laws, the state is the domicile of over 50% of all NYSE-listed business and 60% of the Fortune 500.
The state was named after the Delaware River, which in turn derived its name from Thomas West, 3rd Baron De La Warr (1577–1618) who was the ruling governor of the Colony of Virginia at the time Europeans first explored the river. The Delaware people, a name used by Europeans for Lenape people indigenous to the Delaware Valley, also derive their name from the same source.
The surname de La Warr comes from Sussex and is of Anglo-Norman origin.  It came probably from a Norman lieu-dit La Guerre. This toponymic could derive from Latin ager, from the Breton gwern or from the Late Latin varectum ( fallow). The toponyms Gara, Gare, Gaire (the sound [ä] often mutated in [æ]) also appear in old texts cited by Lucien Musset, where the word ga(i)ra means gore. It could also be linked with a patronymic from the Old Norse verr.
Delaware is 96 miles (154 km) long and ranges from 9 miles (14 km) to 35 miles (56 km) across, totaling 1,954 square miles (5,060 km2), making it the second-smallest state in the United States after Rhode Island. Delaware is bounded to the north by Pennsylvania; to the east by the Delaware River, Delaware Bay, New Jersey and the Atlantic Ocean; and to the west and south by Maryland. Small portions of Delaware are also situated on the eastern side of the Delaware River sharing land boundaries with New Jersey. The state of Delaware, together with the Eastern Shore counties of Maryland and two counties of Virginia, form the Delmarva Peninsula, which stretches down the Mid-Atlantic Coast.
The definition of the northern boundary of the state is unusual. Most of the boundary between Delaware and Pennsylvania was originally defined by an arc extending 12 miles (19.3 km) from the cupola of the courthouse in the city of New Castle.[ citation needed] This boundary is often referred to as the Twelve-Mile Circle. [b] Although the Twelve-Mile Circle is often claimed to be the only territorial boundary in the U.S. that is a true arc, the Mexican boundary with Texas includes several arcs,  and many cities in the South (such as Plains, Georgia)  also have circular boundaries.
This border extends all the way east to the low-tide mark on the New Jersey shore, then continues south along the shoreline until it again reaches the 12-mile (19 km) arc in the south; then the boundary continues in a more conventional way in the middle of the main channel ( thalweg) of the Delaware River. To the west, a portion of the arc extends past the easternmost edge of Maryland. The remaining western border runs slightly east of due south from its intersection with the arc. The Wedge of land between the northwest part of the arc and the Maryland border was claimed by both Delaware and Pennsylvania until 1921, when Delaware's claim was confirmed.
Delaware is on a level plain, with the lowest mean elevation of any state in the nation.  Its highest elevation, located at Ebright Azimuth, near Concord High School, is less than 450 feet (140 m) above sea level.  The northernmost part of the state is part of the Piedmont Plateau with hills and rolling surfaces. The Atlantic Seaboard fall line approximately follows the Robert Kirkwood Highway between Newark and Wilmington; south of this road is the Atlantic Coastal Plain with flat, sandy, and, in some parts, swampy ground.  A ridge about 75 to 80 feet (23 to 24 m) high extends along the western boundary of the state and separates the watersheds that feed Delaware River and Bay to the east and the Chesapeake Bay to the west.
Since almost all of Delaware is a part of the Atlantic coastal plain, the effects of the ocean moderate its climate. The state lies in the humid subtropical climate (Cfa) zone. Despite its small size (roughly 100 miles (160 km) from its northernmost to southernmost points), there is significant variation in mean temperature and amount of snowfall between Sussex County and New Castle County. Moderated by the Atlantic Ocean and Delaware Bay, the southern portion of the state has a milder climate and a longer growing season than the northern portion of the state. Delaware's all-time record high of 110 °F (43 °C) was recorded at Millsboro on July 21, 1930. The all-time record low of −17 °F (−27 °C) was also recorded at Millsboro, on January 17, 1893. The hardiness zones are 7a and 7b.
The transitional climate of Delaware supports a wide variety of vegetation. In the northern third of the state are found Northeastern coastal forests and mixed oak forests typical of the northeastern United States.  In the southern two-thirds of the state are found Middle Atlantic coastal forests.  Trap Pond State Park, along with areas in other parts of Sussex County, for example, support the northernmost stands of bald cypress trees in North America.

Before Delaware was settled by European colonists, the area was home to the Eastern Algonquian tribes known as the Unami Lenape, or Delaware, who lived mostly along the coast, and the Nanticoke who occupied much of the southern Delmarva Peninsula. John Smith also shows two Iroquoian tribes, the Kuskarawock and Tockwogh, living north of the Nanticoke—they may have held small portions of land in the western part of the state before migrating across the Chesapeake Bay.  The Kuskarawocks were most likely the Tuscarora.
The Unami Lenape in the Delaware Valley were closely related to Munsee Lenape tribes along the Hudson River. They had a settled hunting and agricultural society, and they rapidly became middlemen in an increasingly frantic fur trade with their ancient enemy, the Minqua or Susquehannock. With the loss of their lands on the Delaware River and the destruction of the Minqua by the Iroquois of the Five Nations in the 1670s, the remnants of the Lenape who wished to remain identified as such left the region and moved over the Alleghany Mountains by the mid-18th century. Generally, those who did not relocate out of the state of Delaware were baptized, became Christian and were grouped together with other persons of color in official records and in the minds of their non-Native American neighbors.[ citation needed]
The Dutch were the first Europeans to settle in present-day Delaware in the middle region by establishing a trading post at Zwaanendael, near the site of Lewes in 1631.  Within a year all the settlers were killed in a dispute with area Native American tribes. In 1638 New Sweden, a Swedish trading post and colony, was established at Fort Christina (now in Wilmington) by Peter Minuit at the head of a group of Swedes, Finns and Dutch. The colony of New Sweden lasted 17 years. In 1651 the Dutch, reinvigorated by the leadership of Peter Stuyvesant, established a fort at present-day New Castle, and in 1655 they conquered the New Sweden colony, annexing it into the Dutch New Netherland.   Only nine years later, in 1664, the Dutch were conquered by a fleet of English ships by Sir Robert Carr under the direction of James, the Duke of York. Fighting off a prior claim by Cecil Calvert, 2nd Baron Baltimore, Proprietor of Maryland, the Duke passed his somewhat dubious ownership on to William Penn in 1682. Penn strongly desired access to the sea for his Pennsylvania province and leased what then came to be known as the "Lower Counties on the Delaware"  from the Duke.
Penn established representative government and briefly combined his two possessions under one General Assembly in 1682. However, by 1704 the Province of Pennsylvania had grown so large their representatives wanted to make decisions without the assent of the Lower Counties, and the two groups of representatives began meeting on their own, one at Philadelphia, and the other at New Castle. Penn and his heirs remained proprietors of both and always appointed the same person Governor for their Province of Pennsylvania and their territory of the Lower Counties. The fact that Delaware and Pennsylvania shared the same governor was not unique. From 1703 to 1738 New York and New Jersey shared a governor.  Massachusetts and New Hampshire also shared a governor for some time. 
Dependent in early years on indentured labor, Delaware imported more slaves as the number of English immigrants decreased with better economic conditions in England. The colony became a slave society and cultivated tobacco as a cash crop, although English immigrants continued to arrive.
Like the other middle colonies, the Lower Counties on the Delaware initially showed little enthusiasm for a break with Britain. The citizenry had a good relationship with the Proprietary government, and generally were allowed more independence of action in their Colonial Assembly than in other colonies. Merchants at the port of Wilmington had trading ties with the British.
So it was that New Castle lawyer Thomas McKean denounced the Stamp Act in the strongest terms, and Kent County native John Dickinson became the "Penman of the Revolution." Anticipating the Declaration of Independence, Patriot leaders Thomas McKean and Caesar Rodney convinced the Colonial Assembly to declare itself separated from British and Pennsylvania rule on June 15, 1776. The person best representing Delaware's majority, George Read, could not bring himself to vote for a Declaration of Independence. Only the dramatic overnight ride of Caesar Rodney gave the delegation the votes needed to cast Delaware's vote for independence.
Initially led by John Haslet, Delaware provided one of the premier regiments in the Continental Army, known as the "Delaware Blues" and nicknamed the " Blue Hen's Chicks". In August 1777 General Sir William Howe led a British army through Delaware on his way to a victory at the Battle of Brandywine and capture of the city of Philadelphia. The only real engagement on Delaware soil was the Battle of Cooch's Bridge, fought on September 3, 1777, at Cooch's Bridge in New Castle County, although there was a minor Loyalist rebellion in 1778.
Following the Battle of Brandywine, Wilmington was occupied by the British, and State President John McKinly was taken prisoner. The British remained in control of the Delaware River for much of the rest of the war, disrupting commerce and providing encouragement to an active Loyalist portion of the population, particularly in Sussex County. Because the British promised slaves of rebels freedom for fighting with them, escaped slaves flocked north to join their lines. 
Following the American Revolution, statesmen from Delaware were among the leading proponents of a strong central United States with equal representation for each state.
Many colonial settlers came to Delaware from Maryland and Virginia, where the population had been increasing rapidly. The economies of these colonies were chiefly based on labor-intensive tobacco and increasingly dependent on African slaves because of a decline in working class immigrants from England. Most of the English colonists had arrived as indentured servants (contracted for a fixed period to pay for their passage), and in the early years the line between servant and slave was fluid.
Most of the free African-American families in Delaware before the Revolution had migrated from Maryland to find more affordable land. They were descendants chiefly of relationships or marriages between white servant women and enslaved, servant or free African or African-American men.  Under slavery law, children took the social status of their mothers, so children born to white women were free, regardless of their paternity, just as children born to enslaved women were born into slavery. As the flow of indentured laborers to the colony decreased with improving economic conditions in England, more slaves were imported for labor and the caste lines hardened.
By the end of the colonial period, the number of enslaved people in Delaware began to decline. Shifts in the agriculture economy from tobacco to mixed farming resulted in less need for slaves' labor. In addition local Methodists and Quakers encouraged slaveholders to free their slaves following the American Revolution, and many did so in a surge of individual manumissions for idealistic reasons. By 1810 three-quarters of all blacks in Delaware were free. When John Dickinson freed his slaves in 1777, he was Delaware's largest slave owner with 37 slaves. By 1860, the largest slaveholder owned 16 slaves. 
Although attempts to abolish slavery failed by narrow margins in the legislature, in practical terms the state had mostly ended the practice. By the 1860 census on the verge of the Civil War, 91.7% of the black population were free;  1,798 were slaves, as compared to 19,829 "free colored persons". 
An independent black denomination was chartered in 1813 by freed slave Peter Spencer as the " Union Church of Africans". This followed the 1793 establishment in Philadelphia of the African Methodist Episcopal Church by Richard Allen, which had ties to the Methodist Episcopal Church until 1816. Spencer built a church in Wilmington for the new denomination.  This was renamed as the African Union First Colored Methodist Protestant Church and Connection, more commonly known as the A.U.M.P. Church. In 1814, Spencer called for the first annual gathering, known as the Big August Quarterly, which continues to draw members of this denomination and their descendants together in a religious and cultural festival.
Delaware voted against secession on January 3, 1861, and so remained in the Union. While most Delaware citizens who fought in the war served in the regiments of the state, some served in companies on the Confederate side in Maryland and Virginia Regiments. Delaware is notable for being the only slave state from which no Confederate regiments or militia groups were assembled. Delaware essentially freed the few slaves who were still in bondage shortly after the Civil War[ further explanation needed] but rejected the 13th, 14th, and 15th Amendments to the Constitution; the 13th Amendment was rejected on February 8, 1865, the 14th Amendment was rejected on February 8, 1867, and the 15th Amendment was rejected on March 18, 1869. Delaware officially ratified the 13th, 14th, and 15th amendments on February 12, 1901.
After the Civil War, Democratic governments led by the state's Bourbon aristocracy continued to dominate the state and imposed an explicitly white supremacist regime in the state. The Democratic legislatures declared blacks second-class citizens in 1866 and restricted their voting rights despite the Fifteenth Amendment, ensuring continued Democratic success throughout most of the nineteenth century. 
Beginning in the late nineteenth century, the Wilmington area grew into a manufacturing center. Investment in manufacturing in the city grew from $5.5 million in 1860 to $44 million in 1900.  The most notable manufacturer in the state was the Du Pont Company. Because of Wilmington's growth, local politicians from the city and New Castle County pressured the state government to adopt a new constitution providing the north with more representation. However, the subsequent 1897 constitution did not proportionally represent the north and continued to give the southern counties disproportionate influence. 
As manufacturing expanded, businesses became major players in state affairs and funders of politicians through families such as the Du Ponts. Republican John Addicks attempted to buy a US Senate seat multiple times in a rivalry with the Du Ponts until the passage of the Seventeenth Amendment.  The allegiance of industries with the Republican party allowed them to gain control of the state's governorship throughout most of the twentieth century. The GOP ensured blacks could vote because of their general support for Republicans and thus undid restrictions on black suffrage. 
Delaware benefited greatly from World War I because of the state's large gunpowder industry. The Du Pont Company, the most dominant business in the state by WWI, produced an estimated 40% of all gunpowder used by the Allies during the war. It produced nylon in the state after the war and began investments into General Motors.  Additionally, the company invested heavily in the expansion of public schools in the state and colleges such as the University of Delaware in the 1910s and 1920s. This included primary and secondary schools for blacks and women.  Delaware suffered less during the Great Depression than other states, but the depression spurred further migration from the rural south to urban areas. 
Like in World War I, the state enjoyed a big stimulus to its gunpowder and shipyard industries in World War II. New job opportunities during and after the war in the Wilmington area coaxed African Americans from the southern counties to move to the city. The proportion of blacks constituting the city's population rose from 15% in 1950 to over 50% by 1980.  The surge of black migrants to the north sparked white flight in which middle class whites moved from the city to suburban areas, leading to general segregation of Delaware's society. In the 1940s and 1950s, the state attempted to integrate its schools. The University of Delaware admitted its first black student in 1948, and local courts ruled that primary schools had to be integrated. Delaware's integration efforts partially inspired the US Supreme Court's decision in Brown v. Board of Education. 
However, integration only encouraged more white flight, and poor economic conditions for the black population led to some violence during the 1960s. Riots broke out in Wilmington in 1967 and again in 1968 in response to the assassination of Martin Luther King Jr after which the National Guard occupied the city for nine months to prevent further violence. 
Since WWII, the state has been generally economically prosperous and enjoyed relatively high per capita income because of its location between major cities like Philadelphia, New York, and Washington, DC.  Its population grew rapidly, particularly in the suburbs in the north where New Castle county became an extension of the Philadelphia metropolitan area.  Americans, including migrants from Puerto Rico, and immigrants from Latin America flocked to the state. By 1990, only 50% of Delaware's population consisted of natives to the state. 
2019 estimate 
Delaware's history as a border state has led it to exhibit characteristics of both the Northern and the Southern regions of the United States. Generally, the rural Southern (or "Slower Lower") regions of Delaware below the Chesapeake and Delaware Canal embody a Southern culture,   while densely-populated Northern Delaware above the canal—particularly Wilmington, a part of the Philadelphia metropolitan area—has more in common with that of the Northeast.  The U.S. Census Bureau designates Delaware as one of the South Atlantic States, but it is commonly associated with the Mid-Atlantic States and/or Northeastern United States by other federal agencies, the media, and some residents.      
According to the 2010 United States Census, Delaware had a population of 897,934. The racial composition of the state was:
- 68.9% White American (65.3% Non-Hispanic White, 3.6% White Hispanic)
- 21.4% Black or African American
- 0.5% American Indian and Alaska Native
- 3.2% Asian American
- 0.0% Native Hawaiian and other Pacific Islander
- 3.4% some other race
- 2.7% Multiracial American
|Racial composition||1990 ||2000 ||2010 |

Delaware is the sixth most densely populated state, with a population density of 442.6 people per square mile, 356.4 per square mile more than the national average, and ranking 45th in population. Delaware is one of five states (Maine, Vermont, West Virginia, Wyoming) that do not have a single city with a population over 100,000 as of the 2010 census.  The center of population of Delaware is in New Castle County, in the town of Townsend. 
As of 2011 [update], 49.7% of Delaware's population younger than one year of age belonged to minority groups (i.e., did not have two parents of non-Hispanic white ancestry).  In 2000 approximately 19% of the population were African-American and 5% of the population is Hispanic (mostly of Puerto Rican or Mexican ancestry). 
Note: Births in table do not add up because Hispanics are counted both by their ethnicity and by their race, giving a higher overall number.

- Since 2016, data for births of White Hispanic origin are not collected, but included in one Hispanic group; persons of Hispanic origin may be of any race.
As of 2000, 91% of Delaware residents of age 5 and older spoke only English at home; 5% spoke Spanish. French was the third-most spoken language at 0.7%, followed by Chinese at 0.5% and German at 0.5%.
As of 2014 [update], Delaware is mostly Christian. Although Protestants account for almost half of the population,  the Catholic Church is the largest single denomination in the state. The Association of Religion Data Archives  reported in 2010 that the three largest denominational groups in Delaware by number of adherents are the Catholic Church at 182,532 adherents, the United Methodist Church with 53,656 members reported, and non-denominational Evangelical Protestant with 22,973 adherents reported. The religious body with the largest number of congregations is the United Methodist Church (with 158 congregations) followed by non-denominational Evangelical Protestant (with 106 congregations), then the Catholic Church (with 45 congregations).
The Roman Catholic Diocese of Wilmington and the Episcopal Diocese of Delaware oversee the parishes within their denominations. The A.U.M.P. Church, the oldest African-American denomination in the nation, was founded in Wilmington. It still has a substantial presence in the state. Reflecting new immigrant populations, an Islamic mosque has been built in the Ogletown area, and a Hindu temple in Hockessin.
Delaware is home to an Amish community which resides west of Dover in Kent County, consisting of nine church districts and about 1,650 people. The Amish first settled in Kent County in 1915. In recent years, increasing development has led to the decline in the number of Amish living in the community.   
A 2012 survey of religious attitudes in the United States found that 34% of Delaware residents considered themselves "moderately religious", 33% "very religious", and 33% as "non-religious". 
A 2012 Gallup poll found that Delaware's proportion of lesbian, gay, bisexual, and transgender adults stood at 3.4 percent of the population. This constitutes a total LGBT adult population estimate of 23,698 people. The number of same-sex couple households in 2010 stood at 2,646. This grew by 41.65% from a decade earlier. [ not specific enough to verify] On July 1, 2013, same-sex marriage was legalized, and all civil unions would be converted into marriages.

According to a 2020 study by Kiplinger, Delaware had the seventeenth largest number of millionaires per capita in the United States, with a ratio of 6.98 percent, 0.7 percent from 2013 in ration but falling eight places in ranking. Delaware had 25,937 millionaires as of 2020. The median income for all Delaware households as of 2020 was $64,805.  
The state's largest employers are:[ dubious ]
- government (State of Delaware, New Castle County)
- education ( University of Delaware, Delaware Technical Community College)
- banking ( Bank of America, M&T Bank, JPMorgan Chase, Citigroup, Deutsche Bank)
- chemical, pharmaceutical, technology ( DuPont de Nemours Inc., AstraZeneca, Syngenta, Agilent Technologies)
- healthcare ( Christiana Care Health System ( Christiana Hospital), Bayhealth Medical Center, Alfred I. duPont Hospital for Children)
- farming, specifically chicken farming in Sussex County ( Perdue Farms, Mountaire Farms, Allen Family Foods)
- retail ( Walmart, Walgreens, Acme Markets)
Since the mid-2000s, Delaware has seen the departure of the state's automotive manufacturing industry ( General Motors Wilmington Assembly and Chrysler Newark Assembly), the corporate buyout of a major bank holding company ( MBNA), the departure of the state's steel industry ( Evraz Claymont Steel), the bankruptcy of a fiber mill (National Vulcanized Fibre),  and the diminishing presence of AstraZeneca in Wilmington.  
In late 2015, DuPont announced that 1,700 employees, nearly a third of its footprint in Delaware, would be laid off in early 2016.  The merger of E.I. du Pont de Nemours & Co. and Dow Chemical Company into DowDuPont took place on September 1, 2017.    
More than half of all U.S. publicly traded companies, and 63% of the Fortune 500, are incorporated in Delaware.  The state's attractiveness as a corporate haven is largely because of its business-friendly corporation law. Franchise taxes on Delaware corporations supply about a fifth of the state's revenue.  Although "USA (Delaware)" ranked as the world's most opaque jurisdiction on the Tax Justice Network's 2009 Financial Secrecy Index,  the same group's 2011 Index ranks the U.S. fifth and does not specify Delaware.  In Delaware, there are more than a million registered corporations,  meaning there are more corporations than people.
Title 4, chapter 7 of the Delaware Code stipulates that alcoholic liquor be sold only in specifically licensed establishments, and only between 9:00 a.m. and 1:00 a.m.  Until 2003, Delaware was among the several states enforcing blue laws and banned the sale of liquor on Sunday. 
The transportation system in Delaware is under the governance and supervision of the Delaware Department of Transportation, also known as "DelDOT".   Funding for DelDOT projects is drawn, in part, from the Delaware Transportation Trust Fund, established in 1987 to help stabilize transportation funding; the availability of the Trust led to a gradual separation of DelDOT operations from other Delaware state operations.  DelDOT manages programs such as a Delaware Adopt-a-Highway program, major road route snow removal, traffic control infrastructure (signs and signals), toll road management, Delaware Division of Motor Vehicles, the Delaware Transit Corporation (branded as " DART First State", the state government public transportation organization), among others. In 2009, DelDOT maintained 13,507 lane-miles, totaling 89 percent of the state's public roadway system, the rest being under the supervision of individual municipalities. This far exceeds the national average (20 percent) for state department of transportation maintenance responsibility. 
One major branch of the U.S. Interstate Highway System, Interstate 95 (I-95), crosses Delaware southwest-to-northeast across New Castle County. In addition to I-95, there are six U.S. highways that serve Delaware: U.S. 9, U.S. 13, U.S. 40, U.S. 113, U.S. 202, and U.S. 301. There are also several state highways that cross the state of Delaware; a few of them include DE 1, DE 9, and DE 404. U.S. 13 and DE 1 are primary north–south highways connecting Wilmington and Pennsylvania with Maryland, with DE 1 serving as the main route between Wilmington and the Delaware beaches. DE 9 is a north–south highway connecting Dover and Wilmington via a scenic route along the Delaware Bay. U.S. 40 is a primary east–west route, connecting Maryland with New Jersey. DE 404 is another primary east–west highway connecting the Chesapeake Bay Bridge in Maryland with the Delaware beaches. The state also operates three toll highways, the Delaware Turnpike, which is I-95, between Maryland and New Castle; the Korean War Veterans Memorial Highway, which is DE 1, between Wilmington and Dover; and the U.S. 301 toll road between the Maryland border and DE 1 in New Castle County.
A bicycle route, Delaware Bicycle Route 1, spans the north–south length of the state from the Maryland border in Fenwick Island to the Pennsylvania border north of Montchanin. It is the first of several signed bike routes planned in Delaware. 
Delaware has about 1,450 bridges, 95 percent of which are under the supervision of DelDOT. About 30 percent of all Delaware bridges were built before 1950, and about 60 percent of the number are included in the National Bridge Inventory. Some bridges not under DelDOT supervision includes the four bridges on the Chesapeake and Delaware Canal, which are under the jurisdiction of the U.S. Army Corps of Engineers, and the Delaware Memorial Bridge, which is under the bi-state Delaware River and Bay Authority.[ citation needed]
It has been noted that the tar and chip composition of secondary roads in Sussex County makes them more prone to deterioration than are the asphalt roadways in almost the rest of the state.  Among these roads, Sussex (county road) 236 is among the most problematic. 
Three ferries operate in the state of Delaware:
- Cape May–Lewes Ferry crosses the mouth of Delaware Bay between Lewes, Delaware, and Cape May, New Jersey.
- Woodland Ferry (a cable ferry) crosses the Nanticoke River southwest of Seaford.
- Forts Ferry Crossing connects Delaware City with Fort Delaware and Fort Mott, New Jersey.
Amtrak has two stations in Delaware along the Northeast Corridor; the relatively quiet Newark Rail Station in Newark, and the busier Wilmington Rail Station in Wilmington. The Northeast Corridor is also served by SEPTA's Wilmington/Newark Line of Regional Rail, which serves Claymont, Wilmington, Churchmans Crossing, and Newark.
Two Class I railroads, Norfolk Southern and CSX, provide freight rail service in northern New Castle County. Norfolk Southern provides freight service along the Northeast Corridor and to industrial areas in Edgemoor, New Castle, and Delaware City. CSX's Philadelphia Subdivision passes through northern New Castle County parallel to the Amtrak Northeast Corridor. Multiple short-line railroads provide freight service in Delaware. The Delmarva Central Railroad operates the most trackage of the short-line railroads, running from an interchange with Norfolk Southern in Porter south through Dover, Harrington, and Seaford to Delmar, with another line running from Harrington to Frankford and branches from Ellendale to Milton and from Georgetown to Gravel Hill. The Delmarva Central Railroad connects with the Maryland and Delaware Railroad, which serves local customers in Sussex County.  CSX connects with the freight/ heritage operation, the Wilmington and Western Railroad, based in Wilmington and the East Penn Railroad, which operates a line from Wilmington to Coatesville, Pennsylvania.
The last north–south passenger trains through the main part of Delaware was the Pennsylvania Railroad's local Wilmington-Delmar train in 1965.   This was a successor to the Del-Mar-Va Express and Cavalier, which had run from Philadelphia through the state's interior, to the end of the Delmarva Peninsula until the mid-1950s.  
The DART First State public transportation system was named "Most Outstanding Public Transportation System" in 2003 by the American Public Transportation Association. Coverage of the system is broad within northern New Castle County with close association to major highways in Kent and Sussex counties. The system includes bus, subsidized passenger rail operated by Philadelphia transit agency SEPTA, and subsidized taxi and paratransit modes. The paratransit system, consisting of a statewide door-to-door bus service for the elderly and disabled, has been described by a Delaware state report as "the most generous paratransit system in the United States".  As of 2012 [update], fees for the paratransit service have not changed since 1988. 
As of 2016 [update], there is no scheduled air service from any Delaware airport, as has been the case in various years since 1991. Various airlines had served Wilmington Airport, the latest departure being Frontier Airlines in April 2015. 
Delaware is centrally situated in the Northeast megalopolis region of cities along I-95. Therefore, Delaware commercial airline passengers most frequently use Philadelphia International Airport (PHL), Baltimore-Washington International Thurgood Marshall Airport (BWI) and Washington Dulles International Airport (IAD) for domestic and international transit. Residents of Sussex County will also use Wicomico Regional Airport (SBY), as it is located less than 10 miles (16 km) from the Delaware border. Atlantic City International Airport (ACY), Newark Liberty International Airport (EWR), and Ronald Reagan Washington National Airport (DCA) are also within a 100-mile (160 km) radius of New Castle County.
Dover Air Force Base, one of the largest in the country, is home to the 436th Airlift Wing and the 512th Airlift Wing. In addition to its other responsibilities in the Air Mobility Command, it serves as the entry point and mortuary for U.S. military personnel (and some civilians) who die overseas.
Delaware's fourth and current constitution, adopted in 1897, provides for executive, judicial and legislative branches. 
The Delaware General Assembly consists of a House of Representatives with 41 members and a Senate with 21 members. It sits in Dover, the state capital. Representatives are elected to two-year terms, while senators are elected to four-year terms. The Senate confirms judicial and other nominees appointed by the governor.
The Delaware Constitution establishes a number of courts:
- The Delaware Supreme Court is the state's highest court.
- The Delaware Superior Court is the state's trial court of general jurisdiction.
- The Delaware Court of Chancery deals primarily in corporate disputes.
- The Family Court handles domestic and custody matters.
- The Delaware Court of Common Pleas has jurisdiction over a limited class of civil and criminal matters.
Minor non-constitutional courts include the Justice of the Peace Courts and Aldermen's Courts.
Significantly, Delaware has one of the few remaining Courts of Chancery in the nation, which has jurisdiction over equity cases, the vast majority of which are corporate disputes, many relating to mergers and acquisitions. The Court of Chancery and the Delaware Supreme Court have developed a worldwide reputation for rendering concise opinions concerning corporate law which generally (but not always) grant broad discretion to corporate boards of directors and officers. In addition, the Delaware General Corporation Law, which forms the basis of the Courts' opinions, is widely regarded as giving great flexibility to corporations to manage their affairs. For these reasons, Delaware is considered to have the most business-friendly legal system in the United States; therefore a great number of companies are incorporated in Delaware, including 60% of the companies listed on the New York Stock Exchange. 
The executive branch is headed by the Governor of Delaware. The present governor is John Carney (Democrat), who took office January 17, 2017. The lieutenant governor is Bethany Hall-Long. The governor presents a " State of the State" speech to a joint session of the Delaware legislature annually. 
Delaware is subdivided into three counties; from north to south they are New Castle, Kent and Sussex. This is the fewest among all states. Each county elects its own legislative body (known in New Castle and Sussex counties as County Council, and in Kent County as Levy Court), which deal primarily in zoning and development issues. Most functions which are handled on a county-by-county basis in other states—such as court and law enforcement—have been centralized in Delaware, leading to a significant concentration of power in the Delaware state government. The counties were historically divided into hundreds, which were used as tax reporting and voting districts until the 1960s, but now serve no administrative role, their only current official legal use being in real estate title descriptions. 
The Democratic Party holds a plurality of registrations in Delaware. Until the 2000 presidential election, the state tended to be a Presidential bellwether, sending its three electoral votes to the winning candidate since 1952. This trend ended in 2000 when Delaware's electoral votes went to Al Gore by 13 percentage points. In 2004, John Kerry won Delaware by eight percentage points. In 2008, Democrat Barack Obama defeated Republican John McCain in Delaware by 25 percentage points. Obama's running mate was Joe Biden, who had represented Delaware in the United States Senate since 1973 and was later inaugurated President of the United States in 2021. Obama carried Delaware by 19 percentage points in 2012. In 2016, Delaware's electoral votes went to Hillary Clinton by 11 percentage points. In 2020, Democratic nominee, former vice president and Delaware resident Joe Biden beat incumbent President Donald Trump in the state by over 19 percentage points.  Currently, Democrats hold all positions of authority in Delaware including Senate and House.
Delaware's swing to the Democrats is in part due to a strong Democratic trend in New Castle County, home to 55 percent of Delaware's population (the two smaller counties have only 359,000 people between them to New Castle County's 535,000). New Castle County has not voted Republican in a presidential election since 1988. In 1992, 2000, 2004, and 2016, the Republican presidential candidate carried both Kent and Sussex but lost by double digits each time in New Castle County, which was a large enough margin to swing the state to the Democrats. New Castle County also elects a substantial majority of the legislature; 27 of the 41 state house districts and 14 of the 21 state senate districts are based in New Castle County.
The Democrats have held the governorship since 1993, having won the last seven gubernatorial elections in a row. Democrats presently hold all the nine statewide elected offices, while the Republicans last won two statewide offices in 2014, State Auditor and State Treasurer.
Each of the 50 states of the United States has passed some form of freedom of information legislation, which provides a mechanism for the general public to request information of the government.  In 2011 Delaware passed legislation placing a 15 business day time limit on addressing freedom-of-information requests, to either produce information or an explanation of why such information would take longer than this time to produce. 
Delaware has six different income tax brackets, ranging from 2.2% to 5.95%. The state does not assess sales tax on consumers. The state does, however, impose a tax on the gross receipts of most businesses. Business and occupational license tax rates range from 0.096% to 1.92%, depending on the category of business activity.
Delaware does not assess a state-level tax on real or personal property. Real estate is subject to county property taxes, school district property taxes, vocational school district taxes, and, if located within an incorporated area, municipal property taxes.
In June 2018, Delaware became the first U.S. state to legalize sports betting following the Supreme Court ruling to repeal The Professional and Amateur Sports Protection Act (PASPA).

In the early 1920s, Pierre S. du Pont served as president of the state board of education. At the time, state law prohibited money raised from white taxpayers from being used to support the state's schools for black children. Appalled by the condition of the black schools, du Pont donated four million dollars to construct 86 new school buildings. 
Delaware was the origin of Belton v. Gebhart (1952), one of the four cases which were combined into Brown v. Board of Education, the Supreme Court of the United States decision that led to the end of officially segregated public schools. Significantly, Belton was the only case in which the state court found for the plaintiffs, thereby ruling that segregation is unconstitutional.
Unlike many states, Delaware's educational system is centralized in a state Superintendent of Education, with local school boards retaining control over taxation and some curriculum decisions. This centralized system, combined with the small size of the state, likely contributed to Delaware becoming the first state, after completion of a three-year, $30 million program ending in 1999, to wire every K-12 classroom in the state to the Internet. 
All teachers in the State's public school districts are unionized.  As of January 2012 [update], none of the State's charter schools are members of a teachers union.  One of the State's teachers' unions is Delaware State Education Association (DSEA), whose President as of January 2012 [update] is Frederika Jenner.

Two daily newspapers are based in Delaware, the Delaware State News, based in Dover and covering the two southern counties, and The News Journal covering Wilmington and northern Delaware. The state is also served by several weekly, monthly and online publications.
No standalone television stations are based solely in Delaware. The northern part of the state is served by network stations in Philadelphia and the southern part by network stations in Salisbury, Maryland. Philadelphia's ABC affiliate, WPVI-TV, maintains a news bureau in downtown Wilmington. Salisbury's CBS affiliate, WBOC-TV, maintains bureaus in Dover and Milton. Three Philadelphia-market stations— PBS member WHYY-TV, Ion affiliate WPPX, and MeTV affiliate WDPN-TV—all have Wilmington as their city of license, but maintain transmitters at the market antenna farm in Roxborough and do not produce any Delaware-centric programming.

Delaware has several museums, wildlife refuges, parks, houses, lighthouses, and other historic places.
Rehoboth Beach, together with the towns of Lewes, Dewey Beach, Bethany Beach, South Bethany, and Fenwick Island, comprise Delaware's beach resorts. Rehoboth Beach often bills itself as "The Nation's Summer Capital" because it is a frequent summer vacation destination for Washington, D.C., residents as well as visitors from Maryland, Virginia, and in lesser numbers, Pennsylvania. Vacationers are drawn for many reasons, including the town's charm, artistic appeal, nightlife, and tax-free shopping. According to SeaGrant Delaware, the Delaware beaches generate $6.9 billion annually and over $711 million in tax revenue. 
Delaware is home to several festivals, fairs, and events. Some of the more notable festivals are the Riverfest held in Seaford, the World Championship Punkin Chunkin formerly held at various locations throughout the state since 1986, the Rehoboth Beach Chocolate Festival, the Bethany Beach Jazz Funeral to mark the end of summer, the Apple Scrapple Festival held in Bridgeville, the Clifford Brown Jazz Festival in Wilmington, the Rehoboth Beach Jazz Festival, the Sea Witch Halloween Festival and Parade in Rehoboth Beach, the Rehoboth Beach Independent Film Festival, the Nanticoke Indian Pow Wow in Oak Orchard, Firefly Music Festival, and the Return Day Parade held after every election in Georgetown.
In 2015, tourism in Delaware generated $3.1 billion, which makes up five percent of the state's GDP. Delaware saw 8.5 million visitors in 2015, with the tourism industry employing 41,730 people, making it the 4th largest private employer in the state. Major origin markets for Delaware tourists include Philadelphia, Baltimore, New York City, Washington, D.C., and Harrisburg, with 97% of tourists arriving to the state by car and 75% of tourists coming from a distance of 200 miles (320 km) or less. 
Delaware is also home to two large sporting venues. Dover International Speedway is a race track in Dover, and Frawley Stadium in Wilmington is the home of the Wilmington Blue Rocks, a Minor League Baseball team.
- Professional teams
As Delaware has no franchises in the major American professional sports leagues, many Delawareans follow either Philadelphia or Baltimore teams. In the WNBA, the Washington Mystics enjoy a major following due to the presence of Wilmington native and University of Delaware product Elena Delle Donne. The University of Delaware's football team has a large following throughout the state, with the Delaware State University and Wesley College teams also enjoying a smaller degree of support.
Delaware is home to Dover International Speedway and Dover Downs. DIS, also known as the Monster Mile, is one of only 10 tracks in the nation to have hosted 100 or more NASCAR Cup Series races. Dover Downs is a popular harness racing facility. It is the only co-located horse- and car-racing facility in the nation, with the Dover Downs track located inside the DIS track.
Delaware is represented in rugby by the Delaware Black Foxes, a 2015 expansion club.
Delaware is also the name of a Native American group (called in their own language Lenni Lenape) which was influential in the colonial period of the United States and is today headquartered in Cheswold, Kent County, Delaware. A band of the Nanticoke tribe of American Indians today resides in Sussex County and is headquartered in Millsboro, Sussex County, Delaware.
Several ships have been named USS Delaware in honor of this state.

- "The First to Ratify" would be more accurate, as the beginnings of the states themselves date back to the Declaration of Independence, celebrated July 4, 1776, when what was to become the State of Delaware was still the three lower counties of Pennsylvania with the governor in Philadelphia, and not establishing independence from that body until September 20, 1776. According to Delaware's own website, "Delaware became a state in 1776, just two months after the signing of the Declaration of Independence." (ref- pdf Archived December 23, 2016, at the Wayback Machine) Therefore Delaware was actually the last of the thirteen colonies to establish itself as a state. Additionally, the Delaware State Quarter is minted with this nickname, yet shows Caesar Rodney on horseback in commemoration of how he was the last delegate to show up to the Continental Congress for the historic vote for independence. And with regard to the original Articles of Confederation, Delaware was the 12th of the 13 states to ratify.
