Bambao

Bambao was a Muslim sultanate centred on Iconi on Ngazidja, or Grande Comore, in the Comoros. The island was divided among rival towns, whose rulers had limited authority.

By the fifteenth century Islam had reached the islands, and Bambao shared in Swahili trade linking the Comoros with Kilwa, Sofala and Madagascar. Portuguese ships called in 1503 without occupying the island. From the 1790s Malagasy raiders seized slaves and depopulated towns across the Comoros, until the raids ended in the 1810s.
