Question

At least how many African nations gained their independence after World War II?

Answer 1

There are 54 countries in Africa. Most were colonies before WWII now most are independent nations.

Explanation:

Ethiopia was the only African country that was not a colony before WWI. It feel to the Italians in 1938 and was liberated along with others in the horn of Africa in 1940 when the Italians were defeated.

I would guess at least 50 countries gained their independence since WWII but without going through each one, one at a time I am not sure.
