The Zulus formed a powerful military empire in southern Africa during the 19th century before being defeated in a series of engagements with white Afrikaner and British settlers. Some Zulus still live under the traditional clan system in the province of KwaZulu/Natal, but many now work in the cities. In recent years the Zulu Inkatha movement has been drawn into violent clashes with other black groups in South Africa, particularly the Xhosa, and also into conflict with the outgoing government and the African National Congress in the period of transfer to majority rule, over future constitutional arrangements and demands for Zulu autonomy.
