"Xhosa" is the generic name used for a number of related cultural groups in South Africa. Xhosa groups include the Mpondo, Bomvana, Bhaca, Thembu, Mpondomise, Xesibe, Mfengu, Hlubi, and the Xhosa proper. These Southern Nguni peoples, as they are sometimes called, share a common language, Isixhosa, and are culturally similar to one another. Because of their contact with other peoples in the area over the centuries and the strong influence of colonial powers, as well as missionary contact, it is difficult speak of the traditional culture of the Xhosa. Rather, Xhosa culture today is a blend that has resulted from these influences and others. The Xhosa today are much involved in South African political affair and play a major role in the post-apartheid government.
