Colonization of the Congo began in the late 19th century. King Leopold II of Belgium, frustrated by his nation's lack of international power and prestige, tried to persuade the Belgian government to support colonial expansion around the then-largely unexplored Congo Basin. Their refusal led Leopold to create a state under his own personal rule. With support from a number of Western countries who saw Leopold as a useful buffer between rival colonial powers, Leopold achieved international recognition for the Congo Free State in 1885.
