Answer:
The American Anti-Slavery Society was an abolitionist society founded in 1833 and dissolved in 1870.
Throughout its existence, the Society acted in multiple ways: it promoted rallies, published newspapers and distributed propaganda, sent speakers to promote abolitionist ideals and directed petitions to Congress requesting the suppression of slavery. These activities often provoked violent opposition from groups that attacked the speakers and burned the printing presses, but also counted on the support of associations such as the Boston Female Anti-Slavery Society.
The American Anti-Slavery Society was definitively dissolved in 1870, after the ratification of the Fifteenth Amendment to the Constitution of the United States, which prohibited discrimination based on race, color or previous condition of servitude in the exercise of the right to vote.
