Answer:
The new countries created after colonization were in fact new countries.
Explanation:
As you may already know, colonization created new frontiers across the African continent, which allowed the creation of new countries that did not exist before colonization. These borders were maintained after colonization which allowed the creation of new countries, but not only that. Colonization promoted a mixture of cultures and customs that differentiated the African people to the point that it was not possible to unite them in a single country, even if the borders were redrawn. This mixture of cultures and customs created even more differences among African peoples, strengthening the creation of new countries after colonization.
