What did the antislavery group do?

The antislavery group, primarily active in the 19th century, worked to end the institution of slavery and promote the rights of enslaved individuals. They organized protests, published pamphlets, and spread awareness about the inhumane conditions of slavery. Additionally, they supported the Underground Railroad, assisted runaway slaves, and lobbied for legislative changes to abolish slavery. Their efforts contributed significantly to the eventual passage of the Thirteenth Amendment in the United States.
