February 11, 1790 - The Pennsylvania Society for Promoting the Abolition of Slavery, composed mostly of Quakers and Mennonites, petitioned Congress for emancipation of all slaves. Benjamin Franklin had become vocal as an abolitionist and in 1787 began to serve as President of the Society which not only advocated the abolition of slavery, but made efforts to integrate freed slaves into American society.The proposed resolution was immediately denounced by pro-slavery congressmen and sparked a heated debate in both the House and the Senate.#ThePennsylvaniaSocietyForPromotingTheAbolitionOfSlaver
