The area was inhabited by Native Americans for more than 2,800 years, with historical tribes such as the Lenape along the coast. In the early 17th century, the Dutch and the Swedes made the first European settlements. The British later seized control of the region, naming it the Province of New Jersey. It was granted as a colony to Sir George Carteret and John Berkeley, 1st Baron Berkeley of Stratton. At this time, it was named after the largest of the British Channel Islands, Jersey, Carteret's birthplace. New Jersey was the site of several decisive battles during the American Revolutionary War.
In the 19th century, factories in cities such as Paterson, Newark, Trenton, and Elizabeth helped to drive the Industrial Revolution. New Jersey's geographic location at the center of the Northeast megalopolis, between Boston and New York City to the northeast, and Philadelphia, Baltimore, and Washington, D.C., to the southwest, fueled its rapid growth through the process of suburbanization in the 1950s and beyond.
