History of New York City

1700s. It also became a center of slavery, with 42% of households holding slaves by 1730, more than any other city other than Charleston, South Carolina. Most slaveholders held a few or several domestic slaves, but others hired them out to work at labor. Slavery became integrally tied to New York's economy through the labor of slaves throughout the port, and the banks and shipping tied to the South. Discovery of the African Burying Ground in the 1990s during construction of a new federal courthouse near Foley Square revealed that tens of thousands of Africans had been buried in the area in the colonial years.

The trial in Manhattan of John Peter Zenger in 1735 helped to establish the freedom of the press in North America. In 1754, Columbia University was founded under charter by King George II as King's College in Lower Manhattan. The Stamp Act Congress met in New York in October 1765 as the Sons of Liberty organized in the city, skirmishing over the next ten years with British troops stationed there.

The Battle of Long Island, the largest battle of the American Revolutionary War, was fought in August 1776 entirely within the modern-day borough of Brooklyn. After the battle, in which the Americans were defeated, leaving subsequent smaller armed engagements following in its wake, the city became the British military and political base of operations in North America. The city was a haven for Loyalist refugees, as well as escaped slaves who joined the British lines for freedom newly promised by the Crown for all fighters. As many as 10,000 escaped slaves crowded into the city during the British occupation. When the British forces evacuated at the close of the war in 1783 they transported 3,000 freedmen for resettlement in Nova Scotia. They resettled other freedmen in England and the Caribbean.
