In 1676 the colony was divided between Carteret and a company of English Quakers who had obtained the rights belonging to John, Lord Berkeley. New Jersey became a united, crown colony in 1702, administered by the royal governor of New York. Finally, in 1738, New Jersey was separated from New York under its own royal governor, Lewis Morris. Because of its key location between New York City and Philadelphia, New Jersey saw much fighting during the American Revolution.

Today, New Jersey, an area of wide industrial diversification, is known as the Crossroads of the East. Products from over 15,000 factories can be delivered overnight to almost 60 million people, representing 12 states and the District of Columbia. The greatest single industry is chemicals; New Jersey is one of the foremost research centers in the world. Many large oil refineries are located in northern New Jersey. Other important manufactured items are pharmaceuticals, instruments, machinery, electrical goods, and apparel.

In 1977, New Jersey voters approved legislation allowing legalized casino gambling in Atlantic City. Points of interest include the Delaware Water Gap, the Edison National Historic Site in West Orange, Princeton University, Liberty State Park, Jersey City, and the N.J. State Aquarium in Camden (opened 1992).
