[SLAVERY & ABOLITION]. GARRISON, William Lloyd (1805-1879). Declaration of Sentiments of the American Anti-Slavery Society. Adopted at the Formation of said Society, in Philadelphia, on the 4th day of December, 1833. New York: William S. Dorr for The American Anti-Slavery Society, 1833. 8vo (229 x 146 mm), 4pp. Single-sheet folded once. AN IMPORTANT FOUNDING DOCUMENT OF THE AMERICAN ABOLITIONIST MOVEMENT. “The Convention assembled in the city of Philadelphia, to organize a National Anti-Slavery Society, promptly seize the opportunity to promulgate the following Declaration of Sentiments, as cherished by them in relation to the enslavement of one-sixth portion of the American people...” This rare tract, issued on the occasion of the first meeting of the American Anti-Slavery Society, set forth their goals, chief among them the immediate end to slavery throughout the United States. Founded under the leadership of William Lloyd Garrison, he and his followers would denounce the U.S. Constitution as a pro-slavery document, going so far as to publicly burn a copy in 1854, decrying it a “covenant with death, and an agreement with Hell”. Following the Civil War and Emancipation, the AASS was formally dissolved in 1870.
