The Banyoro, Batoro, and Banyankole people of western Uganda are classified as Western Lacustrine Bantu language speakers. Their complex kingdoms are believed to be the product of acculturation between two different ethnic groups, the Hima (Bahima) and the Iru (Bairu). In each of these three societies, two distinct physical types are identified as Hima and Iru. The Hima are generally tall and are believed to be the descendants of pastoralists who migrated into the region from the northeast. The Iru are believed to be descendants of agricultural populations that preceded the Hima as cultivators in the region.
