Disputes arose between the Dutch and the English for control of this territory. In 1667, during negotiations leading to the Treaty of Breda after the Second Anglo-Dutch War, the Dutch decided to keep the nascent plantation colony of Surinam they had gained from the English. In return the English kept New Amsterdam, the main city of the former colony of New Netherland in North America on the mid-Atlantic coast. The British renamed it after the Duke of York: New York City.
