What powers didn't have a colonies in west Africa by 1900?

By 1900, major European powers like Germany and Italy did not possess colonies in West Africa. While Britain and France had established significant colonial territories in the region, Germany's colonial ambitions were primarily focused on areas in East Africa and Cameroon, while Italy had limited investments in Africa overall. The lack of colonies in West Africa for these countries reflected the competitive nature of European Imperialism during this period.
