Isithembu means polygamy and is still a custom in many parts of Africa. Isithembu (also called Sethepu) is the African custom of a man being able to have more than one wife at the same time. There were and are several situations that allow a man to have additional wives. A man may marry again if his current wife or wives cannot have children. He keeps his current wife or wives as divorce is not allowed. She becomes the senior wife, a position of honor. A man may marry again if his current wife or wives have not produced male children. He can marry again if a wife does not want children. In some places, if a man dies, his wife or wives are married to his brother. This way his family is cared for. The Swazi culture says a man should have many wives. Polygamy (Isithembu) is normal for men. Woman should have children, which is normal for them.
