New Jersey is a state in both the Mid-Atlantic and Northeastern regions of the United States. It is the most densely populated state and at the center of the Northeast megalopolis. New Jersey is bordered on its north and east by New York state; on its east, southeast, and south by the Atlantic Ocean; on its west by the Delaware River and Pennsylvania; and on its southwest by Delaware Bay and Delaware. At 7,354 square miles (19,050 km2), New Jersey is the fifth-smallest state in land area, but with close to 9.3 million residents as of the 2020 United States census, it ranks 11th in population. The state capital is Trenton, and the state's most populous city is Newark. New Jersey is the only U.S. state in which every county is deemed urban by the U.S. Census Bureau.
New Jersey was first inhabited by Paleo-Indians as early as 13,000 B.C.E. The Lenape were the dominant Indigenous group when Europeans arrived in the early 17th century, and they were subdivived into dialectal groups such as the Munsee, in the north, and the Unami and the Unalachtigo, elsewhere.[10][11] Dutch and Swedish colonists founded the first European settlements in the state,[12] with the British later seizing control of the region and establishing the Province of New Jersey, named after Jersey.[13][14] The colony's fertile lands and relative religious tolerance drew a large and diverse population. New Jersey was among the Thirteen Colonies that supported the American Revolution, hosting several pivotal battles and military commands in the American Revolutionary War. New Jersey remained in the Union during the American Civil War and provided troops, resources, and military leaders in support of the Union Army. After the war, the state emerged as a major manufacturing center and a leading destination for immigrants, helping drive the Industrial Revolution in the U.S. New Jersey was the site of many industrial, technological, and commercial innovations.[15] Many prominent Americans associated with New Jersey have proven influential nationally and globally, including in academia, advocacy, business, entertainment, government, military, non-profit leadership, and other fields.
New Jersey's central location in the Northeast megalopolis helped fuel its rapid growth and suburbanization in the second half of the 20th century. Since the beginning of the 21st century, the state's economy has become highly diversified, with major sectors including biotechnology, pharmaceuticals, information technology, finance, and tourism, and it has become an Atlantic seaboard epicenter for logistics and distribution. New Jersey remains a major destination for immigrants and is home to one of the world's most multicultural populations.[16][17] Echoing historical trends, the state has increasingly re-urbanized, with growth in cities outpacing suburbs since 2008.[18]
New Jersey is one of the most educated, wealthiest, healthiest, diverse and highly developed states in the U.S. ranking it high in several quality of life metrics.[19] As of 2022, New Jersey had the highest annual median household income, at $96,346, of all 50 states.[20] Almost one-tenth of all households in the state, or over 323,000, are millionaires, the highest representation of millionaires among all states.[21] New Jersey's public school system consistently ranks at or among the top of all U.S. states.[22][23][24][25] In 2024, New Jersey was ranked as having the second-healthiest population overall.[26] New Jersey was ranked as the fourth most diverse state in 2024.[27] New Jersey ranks near the top on both the American Human Development Index and the standard Human Development Index. According to climatology research by the U.S. National Oceanic and Atmospheric Administration, New Jersey has been the fastest-warming state by average air temperature over a 100-year period beginning in the early 20th century, which has been attributed to warming of the North Atlantic Ocean.[28]
The pressure of collision between North America and Africa gave rise to the Appalachian Mountains. Around 18,000 years ago, the Ice Age resulted in glaciers that reached New Jersey. As glaciers retreated, they left behind Lake Passaic along with rivers, meadows, swamps, and gorges.[29]
Since the 6th millennium BC, Native American people have inhabited New Jersey, beginning with the Lenape tribe. Scheyichbi is the Lenape name for the land that represents present-day New Jersey.[30] The Lenape were several autonomous groups that practiced maize agriculture in order to supplement their hunting and gathering in the region surrounding the Delaware River, the lower Hudson River, and western Long Island Sound. The Lenape were divided into matrilineal clans that were based upon common female ancestors. Clans were organized into three distinct phratries identified by their animal sign: Turtle, Turkey, and Wolf. They first encountered the Dutch in the early 17th century, and their primary relationship with the Dutch and later European settlers was through fur trade.
The Dutch were the first Europeans to lay claim to lands in New Jersey. The Dutch colony of New Netherland consisted of parts of the modern Mid-Atlantic states. Although the European principle of land ownership was not recognized by the Lenape, Dutch West India Company policy required its colonists to purchase land that they settled. The first to do so was Michiel Pauw, who established a patron ship called Pavonia in 1630 along North River, that eventually became Bergen. Peter Minuit's purchase of lands along the Delaware River established the colony of New Sweden, that lasted until the Dutch conquered it in 1655. Then the entire region became a territory of England on June 24, 1664, after an English fleet under command of Colonel Richard Nicolls sailed into what is now New York Harbor and took control of Fort Amsterdam, annexing the entire province.
During the English Civil War, the Channel Island of Jersey remained loyal to the British Crown and gave sanctuary to the King. In the Royal Square in St Helier, Charles II of England was proclaimed King in 1649, following the execution of his father, Charles I. North American lands were divided by Charles II, who gave his brother, the Duke of York (later King James II), the region between New England and Maryland as a proprietary colony (as opposed to a royal colony). James then granted land between the Hudson River and the Delaware River (the land that would become New Jersey) to two friends who had remained loyal through the English Civil War: Sir George Carteret and Lord Berkeley of Stratton.[31] The area was named the Province of New Jersey.
Since its inception, New Jersey has been characterized by ethnic and religious diversity. New England Congregationalists settled alongside Scots Presbyterians and Dutch Reformed migrants. While the majority of residents lived in towns with individual landholdings of 100 acres (40 ha), a few rich proprietors owned vast estates. English Quakers and Anglicans owned large landholdings. Unlike Plymouth Colony, Jamestown and other colonies, New Jersey was populated by a secondary wave of immigrants who came from other colonies instead of those who migrated directly from Europe. New Jersey remained agrarian and rural throughout the colonial era, and commercial farming developed sporadically. Some townships, such as Burlington on the Delaware River and Perth Amboy, emerged as important ports for shipping to New York City and Philadelphia. The colony's fertile lands and tolerant religious policy drew more settlers, and New Jersey's population had increased to 120,000 by 1775.
Settlement for the first ten years of English rule took place along the Hackensack River and Arthur Kill. Settlers came primarily from New York and New England. On March 18, 1673, Berkeley sold his half of the colony to Quakers in England, who settled the Delaware Valley region as a Quaker colony, with William Penn acting as trustee for the lands for a time. New Jersey was governed as two distinct provinces, East and West Jersey, for 28 years between 1674 and 1702, which were part of the Dominion of New England from 1686 to 1689.
In 1702, the two provinces were reunited under a royal governor rather than a proprietary one. Edward Hyde, titled Lord Cornbury, became the first governor of the royal colony. Britain believed that he was an ineffective and corrupt ruler, taking bribes and speculating on land. In 1708, he was recalled to England. New Jersey was then ruled by the governors of New York, but this infuriated the settlers of New Jersey, who accused these governors of favoritism to New York. Judge Lewis Morris led the case for a separate governor, and was appointed governor by King George II in 1738.[32]
