Zimba (East Africa)
Zimba was a term used by 16th-century Portuguese records to refer to militaristic African groups, and is also found in some Zambezian oral traditions. The term was variously applied to a mercenary group used by Lundu of the Maravi Empire which defeated the Portuguese twice in the 1590s, and a group that attacked the Swahili city-states of Kilwa, Mombasa, and Malindi, which also accordingly intervened decisively against the Ottomans in the 1589 Battle of Mombasa. Scholars have varying interpretations of how connected the aforementioned events were.
