when was slavery outlawed in new york state
History of slavery in New York After the American Revolution, the New York Manumission Society was founded in 1785 to work for the abolition of slavery and for aid to free blacks. The state passed a 1799 law for gradual abolition; after that date, children born to slave mothers were free but required to work for the mother's master for an extended period as indentured servants into their late twenties. Existing slaves kept their status. All remaining slaves were finally freed on July 4, 1827.
