Answer 2

Between the 1870s and 1900, Africa faced European imperialist aggression, diplomatic pressures, military invasions, and eventual conquest and colonization. At the same time, African societies put up various forms of resistance against the attempt to colonize their countries and impose foreign domination. By the early twentieth century, however, much of Africa, except Ethiopia and Liberia, had been colonized by European powers
