When did MOST African colonies receive their independence from European powers?

Between 1945 and 1960, three dozen new states in Asia and Africa achieved autonomy or outright independence from their European colonial rulers. There was no one process of decolonization. In some areas, it was peaceful, and orderly. In many others, independence was achieved only after a protracted revolution.

That really sucks, but i don't know who your leader is, and i don't want to write that much
