Under such influential United States founders as Alexander Hamilton and John Jay, the New York Manumission Society worked for abolition and established the African Free School to educate Black children. It was not until 1827 that slavery was completely abolished in the state, and free Blacks struggled afterward with discrimination. New York interracial abolitionist activism continued; among its leaders were graduates of the African Free School. New York city’s population jumped from 123,706 in 1820 to 312,710 by 1840, 16,000 of whom were Black.
