PLEASE I WILL MARK BRANLIEST what are the two causes of national unity in Africa???

I believe one cause or nationan unity is the borders that went around africa, because they had somelands that couldn't be taken because they had settlers there. Another cause was the europeons were trying to carve Africa into getting more lands. those are the reasons why i think those were the causes.
