re: Boardwalk Empire (S.4, Ep 3) "Acres of Diamonds"

I think Liberia and Ethiopia were the only truly independent countries in Africa in the 1920s. South Africa was somewhat independent but was a dominion of the UK still at the time. They weren't truly independent until the 30s. Egypt kinda had the same deal as well until the 50s. Libya gained independence in the 50s also and pretty much everybody else was 1960. I hope I remembered my African history correctly.
