Tags: Political Party.
The Liberty Party was a minor political party in the United States in the 1840s (with some offshoots surviving into the 1850s and 1860s). The party was an early advocate of the abolitionist cause. It broke away from the American Anti-Slavery Society (AASS) to advocate the view that the Constitution was an anti-slavery document; William Lloyd Garrison leader of the AASS held the contrary view that the Constitution should be condemned as an evil pro-slavery document.
