The New York Manumission Society was an early American organization founded in 1785 by U.S. Founding Father John Jay to promote the abolition (or Manumission) of slaves of African descent within the state of New York. The organization was made up entirely of white men, most of whom were wealthy and held influential positions in society. Throughout its history, which ended in 1849, the society battled against the slave trade; and for the eventual emancipation of all the slaves in the state. It founded the African Free School for the poor and orphaned children of slaves and free people of color.
John Jay had been a prominent leader in the antislavery cause since 1777, when he drafted a state law to abolish slavery. The draft failed, as did a second attempt in 1785. In 1785, all state legislators except one voted for some form of gradual emancipation. However, they did not agree on what civil rights would be given to the slaves once they were freed. In 1799, an emancipation bill passed by ignoring the subject of civil rights for freed slaves at all.
Jay brought in prominent political leaders such as Alexander Hamilton. He also worked closely with Aaron Burr, later head of the Democratic-Republicans in New York. The Society started a petition against slavery, which was signed by almost all the politically prominent men in New York, of all parties and led to a bill for gradual emancipation. Burr, in addition to supporting the bill, made an amendment for immediate abolition, which was voted down.
Jay founded the "New-York Society for Promoting the Manumission of Slaves, and Protecting Such of Them as Have Been, or May be Liberated" (New York Manumission Society), and became its first president in 1785.
