What is "urewe"

The Urewe culture developed and spread in and around the Lake Victoria region of Africa during the African Iron Age. The culture's earliest dated artefacts are located in the Kagera Region of Tanzania, and it extended as far west as the Kivu region of the Democratic Republic of the Congo, as far east as the Nyanza and Western provinces of Kenya, and north into Uganda, Rwanda and Burundi. Sites from the Urewe culture date from the Early Iron Age, from the 5th century BC to the 6th century AD.
