Definition: The Urewe Culture is the name given to the first group of iron producers in the Lake Victoria region of Kenya, Rwanda, the Democratic Republic of the Congo, Uganda, and Tanzania in eastern and central Africa. The Urewe were probably cattler herders and millet and sorghum farmers, and made a distinctive pottery with dimples and concentric lines, which is similar to that of Kalambo Falls in Tanzania. Urewe sites are Early Iron Age, dating to the early 3rd through 6th century AD.
