John Jay, first Chief Justice of the Supreme Court of the United States as well as statesman Alexander Hamilton and the lexicographer Noah Webster, along with many slave holders among its founders. Its mandate was to promote gradual emancipation and to advocate for those already emancipated. New York ended slavery in 1827. The Society was disbanded in 1849, after its mandate was perceived to have been fulfilled.[1][2] the society battled against the slave trade, and for the eventual emancipation of all the slaves in the state. In 1787, they founded the African Free School to teach children of slaves and free people of color, preparing them for life as free citizens. The school produced leaders from within New York's Black community.[1]
