the name taken by Changa, son of Mwene Mutapa Matope, by adding the Arabic title amir (commander) to his given name. On his father’s death he killed Nyahuma, the lawful successor. His own son fought Chikuyo, Nyahuma’s son, until 1502. He began the dismemberment of the Rozvi empire. His kingdom was known also as Butwa and lasted until the early 19th century, when the Nguni destroyed it. His successors built a number of stone monuments and added to the Great Zimbabwe.
