Your challenge, should you choose to accept it, is to reunite the Kingdom of the Kongo--though it needn't be a kingdom if you don't think it should be--with a POD, or at least the first major butterflies, happening after WWI. Bonus points if the POD is after WWII.
EDIT: I change my mind about the post-WWII being worth bonus points thing. Doesn't actually sound very desirable.
