What organization was founded in 1833 by William Lloyd Garrison and other abolitionists, advocating for an end to slavery?

The American Anti-Slavery Society, founded in 1833 by William Lloyd Garrison and other abolitionists, was a significant organization in the movement to end slavery in the United States. Its formation marked a collective effort to organize abolitionists who were committed to the immediate emancipation of enslaved people. The society aimed to educate the public about the moral and ethical issues surrounding slavery, mobilize opposition to the institution, and support former slaves.

Garrison, a prominent journalist and activist, used his influential newspaper "The Liberator" to advance the cause of abolition and spread awareness of anti-slavery sentiments, but "The Liberator" was actually a publication rather than an organization. The National Woman Suffrage Association focused on women's right to vote and was established in 1869, and the Underground Railroad was a network aiding enslaved people in their escape to freedom, rather than a formal organization advocating against slavery on a national level. Thus, the American Anti-Slavery Society stands out as the key organization founded explicitly to combat slavery during this period.
