The Kavango people, also known as the vaKavango, reside on the Namibian side of the NamibianaonAngolan border along the Kavango River. They are mainly riverine living people, but about 20% reside in the dry inland. Their livelihood is based on fishery, livestock-keeping and cropping (mainly pearl millet). The Kavango Region of Namibia is named after the people. In traditional politics they are divided into five kingdoms (Kwangali, Mbunza, Shambyu, Gciriku and Mbukushu), each headed by a hompa or fumu, both meaning "king". Traditional law is still in use and legitimized by the Namibian constitution. The Kavango people are matrilinear. The most common language spoken is RuKwangali (in Kwangali and Mbunza territory); also spoken are Shambyu, Gciriku, and Mbukushu in the corresponding territories. Their religion is mainly Christian although traditional elements still have a place.
