New York City traces its origins to Fort Amsterdam and a trading post founded on Manhattan Island by Dutch colonists around 1624. The settlement was named New Amsterdam in 1626 and was chartered as a city in 1653. The city came under English control in 1664 and was temporarily renamed New York after King Charles II granted the lands to his brother, the Duke of York, before being permanently renamed New York in November 1674. New York City was the U.S. capital from 1785 until 1790. The modern city was formed by the 1898 consolidation of its five boroughs: Manhattan, Brooklyn, Queens, The Bronx, and Staten Island, and has been the largest U.S. city ever since.
