After World War 2, many African countries gained independence from European colonial rule. This included Congo gaining independence from Belgium in 1960 and facing civil war, Ghana becoming the first sub-Saharan country independent from Britain in 1957, and Kenya achieving independence in 1963. However, newly independent countries faced many challenges, and conflicts arose in Nigeria during its decolonization and in Rwanda with the 1994 genocide between Hutus and Tutsis. Pan-African movements also sought to promote unity among the newly independent states.
