One of those events in OTL that would probably be dismissed as implausible if it was in an ATL is the settlement of Madagascar. The island is usually thought to have been settled by both Bantu people and seafearers from Borneo about 2000 years ago. Today the Malagasy language is Austronesian and closely related to many Borneans languages.
But what if the Borneans never settled Madagascar and the island was instead being settled only by mainland Africans?
What would happen when the Arabs and Europeans arrive?
