A map of a decolonized Africa that shows the following divergences:
-Mobutu dies before the Congolese independence. Under the Lumunba government, the country fails to control its eastern areas, but reaches a relative democratic stability and more prosperity.
.-Nigeria suffers a much more virulent civil war.
-The French Western Africa gets independece as a single federation... that implodes in epic-scale ethnic conflicts after it becomes the playground of a megalomaniac dictator. Betweeen her ex-territories is a militaristic and insanely expansionist Upper Volta. There is an extense remnant, the Sahel Empire, under an "emperor" that combines Mobutu's corruption, Idi Amin's paranoia, and Bokassa's grandeur delusions.
-Sudan is split up in First Sudanese civil war. South Sudan ends up federating with TTL's Central African Republic out of pragmatic and ethnic reasons.
-East Africa does much better. The Ethiopian Empire is in the midst of an economic miracle, and though authoritarian, it's a good place for African standards, that swallowed a war-torn Somalia. The East African Republic is a federation founded under a sensible "African renaissance" ideology, with a consolidated non-aligned stance.
-A bloodier Algerian war, deriving much later in an Islamic Revolution.
-A Qadaffi analogue emerges in Libya (the main difference being his Arab origin), claiming to be the new leader of Arab socialism. He manages to get Egypt on his board, but his anti-Bedouine policies lead to a de facto independent state in southeastern Libya (after a massive exodus).
-An earlier Rwandan genocide, and an aggresive and expansionist Hutu regime.
-Djibouti remains as a French territory. Equatorial guinea remains as a Spanish territory.
-No green march. Western Sahara gets independence during the Spanish transition. Morocco has experienced greater democratic reforms.
-An alternate, much more violent ANC in south Africa. A civil war explodes in SA in the early 70's, with part of the territory developing a "Revolutionary Republic" (Basically a pseudo-marxist single party state with a reversed apartheid)
-Portuguese colonialism and regime lasts some years more. Angola is relatively analogue to OTL, Mozambique establishes a Revolutionary Republic. After an edgier Portuguese revolution, a Salazarist remnant stablishes his stronghold in Guinea Bissau, Cape Verde and Sao Tome and Principe... an unstable and psychotic hermit kingdom.
