Congo River is a territory of Democratic Republic of Congo
Bantu, Sudanic, and other migrants from West and Northeastern Africa arrived in the Congo River Basin between 2000 B.C. and A.D. 500. The territory that is now the Democratic Republic of the Congo is extremely diverse, with more than 200 ethnic groups that trace their histories to many communal organizations and kingdoms. The Kingdom of Kongo, for example, ruled the area around the mouth of the Congo River from the 14th to 19th centuries. Meanwhile, the Kingdoms of Luba and Lunda, located to the south and east, were also notable political groupings in the territory and ruled from the 16th and 17th centuries to the 19th century. European prospectors in the Congo Basin invaded and splintered these kingdoms in the late 1800’s, sponsored by King LEOPOLD II of Belgium, and the kingdoms were eventually forced to grant Leopold the rights to the Congo territory as his private property. During this period, known as the Congo Free State, the king's private colonial military forced the local population to produce rubber. From 1885 to 1908, millions of Congolese people died as a result of disease, inhumane treatment, and exploitation.
