Elizabeth was founded in 1664 by English settlers and was named for the wife of Sir George Carteret, not Queen Elizabeth I as many people assume. Originally called "Elizabethtown," and part of the Elizabethtown Tract, it was the first English speaking community formed in the new colony. It was also the first capital of New Jersey. During the American Revolutionary War, Elizabeth was constantly attacked by British forces based in Manhattan and Staten Island.
