The movement aimed at ending slavery in the United States is known as the Abolitionist Movement. Originating in the late 18th century and gaining momentum through the 19th century, this movement sought to abolish slavery and promote equal rights for African Americans. It comprised various individuals and groups, including Frederick Douglass, Harriet Tubman, and William Lloyd Garrison, who advocated for emancipation through speeches, writings, and direct action. The movement played a crucial role in raising awareness about the moral and ethical issues surrounding slavery, ultimately contributing to the Civil War and the passing of the 13th Amendment in 1865.
