Gembu, Nigeria
Gembu is a town found on the Mambilla Plateau in Taraba State of Nigeria. It is the headquarters of Sardauna Local Government Area (formerly "Mambilla") in Taraba State. Sitting at an average elevation of about above sealevel, it is among the high elevated towns in Nigeria. History. It was believed from antiquity that the first inhabitants of the Mambilla Plateau are the descendants of the Bantu ancestors. They constitute the Bantu people who stayed in what is modern-day Gembu right after the Bantu expansion across Africa from 4000 to 3500 BCE. Location. Gembu, the administrative name of  the Mambilla Town of Bommi, was taken from the name of a former monarch of the town known as 'Gelmvu'. The town is found on the Mambilla Plateau, in the south-eastern part of Taraba state, close to the border separating Nigeria and Cameroon. This Mambilla region is known in African history [Bami-Yuno & Munlip (2020), Bantu Commonwealth] Bantuists believe that the people inhabiting the Mambilla Region and their neighbours are descendants of the Proto-Bantu ancestors who inhabited the region generally before the Bantu expansion (Zeitlyn & Connell, 2003). They constitute the Bantu or Bantoid people who remained after the  great split and Bantu expansion across Africa beginning after 2000 BC (being described as 'the Bantu who stayed at home')(Zeitlyn and Connell, 2003; Bami-Yuno, 2013; Talla, Akombo, et al, 2016). The following is an excerpt from Chapter One of the book, "The Mambilla Region in African History". By far the most significant event in African pre-history is the ethnogenesis and spread of the Bantu-speaking peoples associated with the Mambilla Region of the Nigeria-Cameroon borderlands (the Mambillobantu Region) in west-central Africa. The Bantu expansion, which many authorities believe to have begun from this region after 2000  B.C until about 1500 AD, led to the ramification of over one-third of Africa by the same category of Africans, the Bantus, covering some thirty African countries today. Most of the people existing in the central and southern Nigeria-Cameroon border region, southern Cameroon, central, eastern and southern Africa today are a result of the Bantu expansion from the this region or the result of a fusion between the Bantu migrants and Nilo-Saharans and Cushites (as in a few communities in East Africa) or Bantu and Pygmies (as in some communities in central Africa). One in every three  Africans today is Bantoid. The Mambilla Region itself was not totally evacuated and the area is still occupied by the Macro-Bantu-speaking Mambilloid peoples who represent the remnants of that great African expansion. Bommi Town (Gembu) is about from the Kyiumdua or Donga River valley. People. Originally, the only inhabitants of Bommi were the 'Bom-bo' or Tungbo Clan of the Mambilla. They constitute the true Bommi people. The Bommi are the central group of the wide Tungbo which include the Mbubo, Ngebo (from Lenge to as far northwest as Tumbuà, Jimau, Nasò, Ngùng, Yénájù Plain, Furrmi, etc.), Gulkal , Mverip, Kwubo, and their Saan Cradle from which point they all expanded. Splinters from the Tungbo are also to be found in Liimila (Mbamnga), Mvurr (Warwar), Tem, Niggi, Ngunochin, etc. Today, Bommi Town (Gembu), being the headquarters of a Local Government Area, has attracted a population diverse in ethnic makeup, which has resulted in the town taking a cosmopolitan shape. People coming from different parts of Nigeria have made the town their home. Cameroonian immigrants can also be found in the town. The local government area, known as "Mambilla" throughout its ancient and contemporary history, was renamed "Sardauna" by the  then Col. Jega, related to the "Sardauna of Sokoto" Ahmadu Bello, when he came as Military Governor of former Gongola State in 1976. This misnomer was quashed in the Second Republic (1979 - 1983) and the ancient name of "Mambilla" was restored. However, on his second coming in 1984, Jega arbitrarily re-imposed the name "Sardauna", a chieftaincy title, on this Local Government Area (previously known as "Mambilla Landschaft", "Mambilla District", "Mambilla-Gashaka Native Authority", Mambilla Division and "Mambilla Local Authority"). Jega imposed the misnomer of "Sardauna" notwithstanding that it was unhistorical and non-autochthonous. It is why Mubi, Ganye, Toungo , Michika and all other areas formerly known as "Sardauna Province" resumed the use of their proper and autochthonous names. The Mambila people make up the largest single ethnic group population in the town, followed by the Kaka, and then the Hausa-Fulanis, the main cattle rearers of the plateau. The Mambilla people, the denizens of this Plateau, were the only inhabitants of the town until colonial rule set in. They are thought to have been in this region for the past five millennia. On the other hand, the first Kaka (Yamba) probably arrived the Plateau in "early German times" (but  remained unnoticed until 1928 (Percival, 1938), while the first isolated grazing visits by the Fulani nomads were in the late 1920s. According to Percival (1938), "No Fulani settled on the Mambilla Plateau until after the British occupation" (1938 Intelligence Report). It is estimated that 85% of the Mambilla Plateau is composed of the Mambilla Group and these number over 500,000 worldwide <'Mambilla Summit", 2004>. There are in addition several minor groups, mainly businessmen and women from other parts of Nigeria and Cameroon, who can be found doing business in the Mambilla Plateau, such as the Igbos, Hausas, Bansos , Kambus, etc. Accessibility. Although in the past, roads leading to Bommi Town (Gembu) on the Mambilla Plateau were poorly maintained and travelling to the town from other parts of Nigeria was difficult, the transport problems improved radically with the construction of the Mambilla Highway linking the plateau to the lowlands west and north of it. Moreover, the road works begun by the Taraba State Government in 2012 has added a greater prospect of ease of communication with the rest of Nigeria..
