Around 180 million years ago, during the Jurassic Period, New Jersey bordered North Africa. The pressure of the 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 the glaciers retreated, they left behind Lake Passaic, as well as rivers, grasslands, swamps, and gorges.
New Jersey was originally settled by Native Americans with the Lenni-Lenape being dominant at the time of contact. Scheyichbi is the Lenape name for the land that is now New Jersey. 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 society was divided into matrilinear clans that were based upon common female ancestors. These 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 Europeans 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 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 the land that they settled. The first to do so was Michiel Pauw who established a patronship called Pavonia in 1630 along the North River which eventually became the Bergen. Peter Minuit’s purchase of lands along the Delaware River established the colony of New Sweden. The entire region became a territory of England on June 24, 1664, after an English fleet under the 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. It was from the Royal Square in St Helier that Charles II of England was proclaimed King in 1649, following the execution of his father, Charles I. The 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 the 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. The area was named the Province of New Jersey.
Since the state’s 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 10 years of English rule took place along 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. (William Penn acted as trustee for the lands for a time.) New Jersey was governed very briefly as two distinct provinces, East and West Jersey, for 28 years between 1674 and 1702, at times part of the Province of New York or Dominion of New England.
In 1702, the two provinces were reunited under a royal governor, rather than a proprietary one. Edward Hyde, Lord Cornbury, became the first governor of the colony as a 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 those 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.
New Jersey was one of the Thirteen Colonies that revolted against British rule in the American Revolution. The New Jersey Constitution of 1776 was passed July 2, 1776, just two days before the Second Continental Congress declared American Independence from Great Britain. It was an act of the Provincial Congress, which made itself into the State Legislature. To reassure neutrals, it provided that it would become void if New Jersey reached reconciliation with Great Britain. New Jersey representatives Richard Stockton, John Witherspoon, Francis Hopkinson, John Hart, and Abraham Clark were among those who signed the United States Declaration of Independence on July 4, 1776.
During the American Revolutionary War, British and American armies crossed New Jersey numerous times, and several pivotal battles took place in the state. Because of this, New Jersey today is often referred to as “The Crossroads of the American Revolution”. The winter quarters of the Continental Army were established there twice by General George Washington in Morristown, which has been called “The Military Capital of the American Revolution.“
On the night of December 25–26, 1776, the Continental Army under George Washington crossed the Delaware River. After the crossing, they surprised and defeated the Hessian troops in the Battle of Trenton. Slightly more than a week after victory at Trenton, Continental Army forces gained an important victory by stopping General Cornwallis’s charges at the Second Battle of Trenton. By evading Cornwallis’s army, the Continental Army was able to make a surprise attack on Princeton and successfully defeated the British forces there on January 3, 1777. Emanuel Leutze’s painting of Washington Crossing the Delaware became an icon of the Revolution.
Cotinental Army forces under Washington’s command met British forces under General Henry Clinton at the Battle of Monmouth in an indecisive engagement in June 1778. Washington’s forces attempted to take the British column by surprise. When the British army attempted to flank the Americans, the Continental Army retreated in disorder. Their ranks were later reorganized and withstood the British charges.
In the summer of 1783, the Continental Congress met in Nassau Hall at Princeton University, making Princeton the nation’s capital for four months. It was there that the Continental Congress learned of the signing of the Treaty of Paris, which ended the war.
On December 18, 1787, New Jersey became the third state to ratify the United States Constitution, which was overwhelmingly popular in New Jersey since it prevented New York and Pennsylvania from charging tariffs on goods imported from Europe. On November 20, 1789, New Jersey became the first in the newly-formed Union to ratify the Bill of Rights.
The 1776 New Jersey State Constitution gave the vote to “all inhabitants” who had a certain level of wealth. This included women and Black people, but not married women because they were not legally permitted to own property separately from their husbands. Both sides, in several elections, claimed that the other side had had unqualified women vote and mocked them for use of “petticoat electors”, whether entitled to vote or not; on the other hand, both parties passed Voting Rights Acts. In 1807, the legislature passed a bill interpreting the constitution to mean universal white male suffrage, excluding paupers; the constitution was itself an act of the legislature and not enshrined as the modern constitution.
On February 15, 1804, New Jersey became the last northern state to abolish new slavery and enacted legislation that slowly phased out existing slavery. This led to a gradual decrease of the slave population. By the close of the American Civil War, about a dozen African Americans in New Jersey were still held in bondage. New Jersey voters eventually ratified the constitutional amendments banning slavery and granting rights to the United States’ black population.
Industrialization accelerated in the northern part of the state following completion of the Morris Canal in 1831. The canal allowed for coal to be brought from eastern Pennsylvania’s Lehigh Valley to northern New Jersey’s growing industries in Paterson, Newark, and Jersey City.
In 1844, the second state constitution was ratified and brought into effect. Counties thereby became districts for the state senate, and some realignment of boundaries (including the creation of Mercer County) immediately followed. This provision was retained in the 1947 Constitution, but was overturned by the Supreme Court of the United States in 1962 by the decision Baker v. Carr. While the Governorship was stronger than under the 1776 constitution, the constitution of 1844 created many offices that were not responsible to him, or to the people, and it gave him a three-year term, but he could not succeed himself.
New Jersey was one of the few Union states (the others being Delaware and Kentucky) to select a candidate other than Abraham Lincoln twice in national elections, and sided with Stephen Douglas (1860) and George B. McClellan (1864) during their campaigns. McClellan, a native Philadelphian, had New Jersey ties and formally resided in New Jersey at the time; he later became Governor of New Jersey (1878–81). (In New Jersey, the factions of the Democratic party managed an effective coalition in 1860.) During the American Civil War, the state was led first by Republican governor Charles Smith Olden, then by Democrat Joel Parker. During the course of the war, between 65,000 and 80,000 soldiers from the state enlisted in the Union army; unlike many states, including some Northern ones, no battle was fought there.
In the Industrial Revolution, cities like Paterson grew and prospered. Previously, the economy had been largely agrarian, which was problematically subject to crop failures and poor soil. This caused a shift to a more industrialized economy, one based on manufactured commodities such as textiles and silk. Inventor Thomas Edison also became an important figure of the Industrial Revolution, having been granted 1,093 patents, many of which for inventions he developed while working in New Jersey. Edison’s facilities, first at Menlo Park and then in West Orange, are considered perhaps the first research centers in the United States. Christie Street in Menlo Park was the first thoroughfare in the world to have electric lighting. Transportation was greatly improved as locomotion and steamboats were introduced to New Jersey.
Iron mining was also a leading industry during the middle to late 19th century. Bog iron pits in the southern New Jersey Pinelands were among the first sources of iron for the new nation. Mines such as Mt. Hope, Mine Hill and the Rockaway Valley Mines created a thriving industry. Mining generated the impetus for new towns and was one of the driving forces behind the need for the Morris Canal. Zinc mines were also a major industry, especially the Sterling Hill Mine.
New Jersey prospered through the Roaring Twenties. The first Miss America Pageant was held in 1921 in Atlantic City; the Holland Tunnel connecting Jersey City to Manhattan opened in 1927; and the first drive-in movie was shown in 1933 in Camden. During the Great Depression of the 1930s, the state offered begging licenses to unemployed residents, the zeppelin airship Hindenburg crashed in flames over Lakehurst, and the SS Morro Castle beached itself near Asbury Park after going up in flames while at sea.
Through both World Wars, New Jersey was a center for war production, especially naval construction. The Federal Shipbuilding and Drydock Company yards in Kearny and Newark and the New York Shipbuilding Corporation yard in Camden produced aircraft carriers, battleships, cruisers, and destroyers. New Jersey manufactured 6.8 percent of total United States military armaments produced during World War II, ranking fifth among the 48 states. In addition, Fort Dix (1917) (originally called “Camp Dix”),Camp Merritt (1917) and Camp Kilmer (1941) were all constructed to house and train American soldiers through both World Wars. New Jersey also became a principal location for defense in the Cold War. Fourteen Nike missile stations were constructed for the defense of the New York City and Philadelphia areas. PT-109, a motor torpedo boat commanded by Lt. (j.g.) John F. Kennedy in World War II, was built at the Elco Boatworks in Bayonne. The aircraft carrier USS Enterprise (CV-6) was briefly docked at the Military Ocean Terminal in Bayonne in the 1950s before she was sent to Kearney to be scrapped. In 1962, the world’s first nuclear-powered cargo ship, the NS Savannah, was launched at Camden.
In 1951, the New Jersey Turnpike opened, facilitating efficient travel by car and truck between North Jersey and metropolitan New York and South Jersey and metropolitan Philadelphia. 1959, Air Defense Command deployed the CIM-10 Bomarc surface-to-air missile to McGuire Air Force Base. On June 7, 1960, an explosion in a CIM-10 Bomarc missile fuel tank caused the accident and subsequent plutonium contamination.
In the 1960s, race riots erupted in many of the industrial cities of North Jersey. The first race riots in New Jersey occurred in Jersey City on August 2, 1964. Several others ensued in 1967, in Newark and Plainfield. Other riots followed the assassination of Martin Luther King Jr. in April 1968, just as in the rest of the country. A riot occurred in Camden in 1971. As a result of an order from the New Jersey Supreme Court to fund schools equitably, the New Jersey legislature passed an income tax bill in 1976. Prior to this bill, the state had no income tax.
In the early part of the 2000s, two light rail systems were opened: the Hudson–Bergen Light Rail in Hudson County and the River Line between Camden and Trenton. The intent of these projects was to encourage transit-oriented development in North Jersey and South Jersey, respectively. The HBLR in particular was credited with a revitalization of Hudson County and Jersey City in particular. Urban revitalization has continued in North Jersey in the 21st century. In 2014, Jersey City’s Census-estimated population was 262,146, with the largest population increase of any municipality in New Jersey since 2010, representing an increase of 5.9% from the 2010 U.S. census, when the city’s population was enumerated at 247,597. Between 2000 and 2010 Newark experienced its first population increase since the 1950s, and by 2020 had rebounded to 311,549.
