New York was originally New Netherland, started by the Dutch Empire in the early 17th century. Late in the century, it surrendered to an English fleet during the Anglo-Dutch Wars and became part of the British Empire. About half the Dutch colony was given to neighboring English colonies. The Battle of Long Island, Battle of Saratoga, and other important battles of the American Revolution were fought in New York and it joined the new United States. The slave trade brought many black people into the state, where they were forced to work for white colonists.
