Fort Amsterdam was a fortification on the southern tip of Manhattan Island at the confluence of the Hudson and East rivers. The fort and the island were the center of trade and the administrative headquarters for the Dutch and then British/Colonial rule of the colony of New Netherland and thereafter the Province of New York. The fort was the nucleus of the settlement on the island and greater area, which was named New Amsterdam by the first Dutch settlers and eventually renamed New York by the English, and was central to much of New York's early history.
