Give me a brief summary of the decolonization of Africa please
During the Cold War, European nations who had set up colonial governments in Africa throughout the 19th and 20th centuries began to transition out of the continent, allowing Africans to set up independent states. Unfortunately, this process was riddled with violence, political turmoil, widespread unrest, and organized revolts. During World War II, Franklin D. Roosevelt and Winston Churchill created the Atlantic Charter, which pointed out that people have the right to self-government, among other things. Anti-colonialists used this as a catalyst for attaining independence from colonial powers.
