New York Slave Revolt. April 7, 1712 Nine whites were killed in a slave revolt in New York City. Planned by 27 slaves, the rebellion was begun by setting fire to an outhouse; as whites came to put the fire out, there were shot. The state militia was called out to capture the rebels and the city of New York responded to the event by strengthening its slave codes. 21 Blacks were executed as participants, and 6 alleged committed suicide.
