a. The American Anti-Slavery Society
The American Anti-Slavery Society was a society originally founded mainly by William Lloyd Garrison in 1833. The organization fought for the immediate abolition of slavery in the United States. This society usually sponsored meetings, wrote journals, signed antislavery petitions and enlisted people to their cause.
b. The American and Foreign Anti-Slavery Society
The American and Foreign Anti-Slavery Society split off from the Anti-Slavery Society in 1840. This was mainly due to the fact that the American and Foreign Anti-Slavery Society advocated moral suasion and political action. It was influenced by anarchism and a hostility to established religion. Some important members were: Arthur and Lewis Tappan, Samuel Cornish, Henry H. Garnet, and Theodore S. Wright.
c. The Liberty Party
The Liberty Party was a political party in the United States which advanced the abolitionist cause and advocated the view that the Constitution was an anti-slavery document. Abolitionists in this party wanted to work within electoral politics and influence people to support abolition. Many Liberal Party members later joined the anti-slavery Free Soil Party, and eventually helped establish the Republican Party.
