In this episode, Zeinab Badawi travels to South Africa, Zimbabwe, Mozambique and Zambia to find out about the powerful kingdoms of southern Africa and their rulers from 10th to 19th century, like the Mutapa kingdom that stretched across portions of eight modern-day southern African countries. Foreign visitors could not believe that this towering civilisation dating from the 1100s was built by Africans. The reality is that Great Zimbabwe is the most striking example of the kingdoms that flourished in southern Africa.
