 Around 200 BC is when the first strong evidence of Early Iron Age settlements were established along Lake Victoria in Buhaya.Iron tools may have helped expand agricultural production in the region which included a combination of cereal crop cultivation (finger millet and sorghum), root-cropping, and the gradual use of beans.Between 800 and 1500 AD, Bahaya lifeways were greatly influenced by other Bantu peoples moving in from an area further north in the African Great Lakes region.
