The Nso are a people of the Bamenda Grassfields in the Northwest Region of Cameroon. Their traditional language is Lamnso (language of Nso) and their capital is Kumbo. Both the people and the capital are sometimes referred to as Banso (people of Nso) - the addition of the Ba prefix is attributed to the Fulani conquerors in the 17th century; the prefix resonates in the names of towns around the area.
The Fon is the traditional ruler. He is both the head of the traditional government and the chief religious authority in charge of keeping the ancestors happy. The Fon is supported in his duties by the seven notables called Vibais. These Vibais are Shufais, whose positions are determined by rather intricate history. These include Shufai Ndzendzev, Tahnkum, Doh, Ruun, Tsenlah, Lun and Yuwar. Over the years other Shufais have been appointed by the Fon of Nso without any major political influence, but for the fact that they get a seat at the lower ends of the seating ranks in the palace. His power is kept in check by regulatory groups such as the "Ngwerong" (also "Nwerong") which is in effect the security arm of the government and enforces decisions taken by the Fon. The Nwerong is solely responsible for enthronement of a new Fon. It is also responsible for replacing Fais and Shufais after the death of the incumbent. Members of the royal families (except the Fons) may not become members of the Nwerong. The "Ngiri" resembles the Nwerong, but is only for princes. New Fons are selected from a group of eligible princes by a system kept secret from those eligible, thus eliminating a possible source of corruption. The present Fon is Sehm Mbinglo I. Young and dynamic, he has reinforced traditional authority and the respect for human dignity despite the pressures of the modern world. The princes are called Wontho and regularly meet in the presence of the Fon to discuss family matters. There are other Fons that generally act as advisers to the Fon of Nso. The existence of these Fons today signifies an evolution in the history of the Nso people. Most of them were ones leaders of independent tribes that through warfare or peaceful negotiations, or through share events of history came to subordinate the Fon of Nso. They are the only ones (along with foreign Fons) that are allowed to bring in their own seats (Kavahs) to the Nso Palace. These, inexhaustively, include the Fons of Oku, Mbiami, Nseh, Nkar, Gwan, Kiluun, Ngashong, Nshokov, Gwarkang, Taabah, etc. The Fons of Oku and Mbiami were once princes of Nso. All the Fons of Nso and Shufai Ndzendzev are members of both the Nwerong and the Ngiri.
