In the United States there was a movement to settle free people of color, both free-born and formerly enslaved, in Africa. This was because they faced racial discrimination in the form of political disenfranchisement and the denial of civil, religious, and social rights. Formed in 1816, the American Colonization Society (ACS) was made up mostly of Quakers and slaveholders. Quakers believed blacks would face better chances for freedom in Africa than in the U.S. While slaveholders opposed freedom for enslaved people, they viewed "repatriation" of free people of color as a way to avoid slave rebellions.
