Recently, I've been thinking about writing a Kenyawank TL, and I began to wonder whether it was plausible for Britain to liberate Kenya, Tanzania, Uganda, Rwanda, Burundi, Somalia, Zambia and Zimbabwe as a single nation?
The POD would be Germany sending Paul Emil von Lettow-Vorbeck to Cameroon instead of Tanzania, leading to the defeat of German forces in East Africa. As a result, once the Germans are defeated Belgium is given parts of Cameroon, and the British get Rwanda, Tanzania and Burundi instead.
After the war, Britain invests heavily in East Africa, eventually conquering both Ethiopia and Somalia by 1925. European farmers that emigrate to the surrounding countryside force the natives out of their homes into the newly vast industrial cities of Mombasa, Nairobi, Mogadishu and Dar es Salaam; the many years of terrible fighting in Europe has taught the British they cannot afford to keep all their eggs in one basket, and it's cheaper to use slave labour in the colonies (which have many raw materials, such as gold and cotton) than pay workers at home. The foundations of education and medicine are installed in most major cities, along with clean water, gas and roads. The Africans may be slaves, but they outnumber the colonists fifty to one, and it is wise to keep your vast number of potentially hostile slaves content.
World War II happens. The investment in Africa pays off. Hundreds of thousands of colonial troops that are extremely loyal to the Empire turn the tide at battles such as Dunkirk, where Britain barely managed to hold off the Germans.
Germany then attacked its ally Russia, who was still recovering from a extremely poor harvest. Moscow is captured in 1942. Stalin commits suicide to avoid being arrested by the Germans, and the USSR dissolves into several military juntas bickering over who owns what.
The war ends in October 1945, with the Allies liberating Warsaw from the few Germans fanatical enough to stay loyal to Hitler, who fled to the city in July. The Fuhrer is tried at Nuremburg with the other high-ranking Nazis, where he is executed for over two hundred seperate offences, including Mass Murder and Crimes against Humanity.
Kenya and the other East African nations are eventually freed in the 1970s, with development levels similiar to mainland Britain.
Is this a plausible scenario?
