Abraham Lincoln was a proponent of colonization (setting up a colony for African-Americans in Africa).
Quoting from my source:
Abraham Lincoln was an avid colonizationist. He quoted with approval Henry Clay's words on the topic. He touted colonization in his annual messages to Congress in 1861 and '62, in his appeal to border-state representatives for compensated emancipation (July 12, 1862), and in the Preliminary Emancipation Proclamation (Sept. 22, 1862). In 1861, addressing Congress, he mentioned contraband slaves who had fallen into the hands of Northern troops, as well as the possibility of border states emancipating their slaves. He advocated that “steps be taken for colonizing both classes, (or the one first mentioned, if the other shall not be brought into existence), at some place, or places, in a climate congenial to them. It might be well to consider, too, -- whether the free colored people already in the United States could not, so far as individuals may desire, be included in such colonization.” A year later, he told Congress, “I cannot make it better known than it already is, that I strongly favor colonization.”
