Liberia happened in 1821, it’s capital is “Monrovia”, named for President James Monroe who helped establish a new homeland in Africa for freed slaves.
The idea of re-colonization of freed slaves was not a revolutionary idea at the time of the Civil War, obviously, since it had already successfully happened a generation before.
As I recall reading, the biggest issue was the money; who would pay to send the slaves back?
I just went back and looked at my reply.......I know you aint gonna believe this but I meant to say “before Lincoln’s time”. I don’t know why I typed the word “after”.
Consider please, I was born only 80 years after Lincoln’s death.
