Political map of Sub-Saharan Africa 01 April 1950 (United Nations Trust Territories): After World War II the League of Nations was replaced by the United Nations and the old League mandates (League of Nations mandates) became UN trust territories. In 1950 Somaliland also became a trust territory (Trust Territory of Somaliland), administered by Italy - its pre-war colonial ruler - on behalf of the UN. Objecting to the UN's push for independence and self-determination in Africa, South Africa rejected UN trusteeship over South West Africa and adopted apartheid - a system of racial segregation under white domination.
