Ethiopia and Liberia weren't colonized and are the only countries in Africa not colonized. But it is worth noting that Ethiopia was occupied. Italy invaded in the mid-1930s, and then, in 1941, England conquered Ethiopia and became its occupiers.
The British I believe. No one country colonized Africa. Several countries divided African during the "Scramble for Africa" timeframe. Countries such as the British, Portuguese, Spain, France, Netherlands
There are 25 countries in Africa that have French as one of the official languages. That means that France has colonized about 25 countries in Africa (Don't forget there have been revalutions and countries have changed.) Most of West Africa speaks French as well as Madagascar.
I believe that the two countries are the dutch and the french.This is true as the Dutch (from Holland or the Netherlands) colonized South Africa and probably some other countries on the African continent. The French (France) colonized the Ivory Coast, now called the Cote d'Ivoir.
