The region that is now the Democratic Republic of the Congo was first settled about 80,000 years ago. Bantu migration arrived in the region from Nigeria in the 7th century AD. The Kingdom of Kongo remained present in the region between the 14th and the early 19th centuries. Belgian colonization began when King Leopold II founded the Congo Free State, a corporate state run solely by King Leopold. Reports of widespread murder and torture in the rubber plantations led the Belgian government to seize the Congo from Leopold II and establish the Belgian Congo. Under Belgian rule, the colony was run with the presence of numerous Christian organizations that wanted to Westernize the Congolese people.
