Niger [River] Valley

Located in West Africa, this valley covers 7.5 percent of the continent and extends through ten countries: Guinea, Côte d'Ivoire (Ivory Coast), Mali, Burkina Faso, Algeria, Benin, Niger, Chad, Cameroon, and Nigeria. One of Africa's eight major river basins, the Niger River Valley follows the course of the Niger River, the largest and longest river in West Africa and the third-longest river on the African continent. In 1859, abolitionist and emigration advocate Martin R. Delany traveled to Liberia and the Niger Valley in an effort to establish a free colony for American blacks; his written account of the expedition, the Official Report of the Niger Valley Exploring Party, was published in 1861.
