On what were the boundaries of the African countries that gained their independence after World War II most often based?

On divisions forced under European imperialism

Explanation:

The boundaries of the African countries that gained their independence after World War II was based on imperialism. The rise of Imperialism brought the rush to invasion, colonization, and expansion in Africa. During those ages, many Europeans tried to explore central portions of the continent to get access to the natural resources and to extend their hold in Africa to make colonies. After World War II, many of the African countries gained independence from European imperialism.
