Thembu people
The Thembu are one of the handful of nations and population groups which speak Xhosa in South Africa. In Xhosa the name is abaThembu, aba- being a common prefix for peoples. In the 19th century they were frequently known as the "Tamboekie" or "Tambookie" people. The most internationally famous Thembu person was Nelson Mandela, whose father was a reigning nobleman from a junior branch of the Madiba clan of kings. Walter Sisulu was also of Thembu descent, on his mother's side. The land in which they lived was historically known as Thembuland.
