Niger State
Niger or Niger State is a state in Central Nigeria and the largest state in the country. The state capital is Minna, and other major cities are Bida, Kontagora, and Suleja. It was formed in 1976 when the then North-Western State was bifurcated into Niger State and Sokoto State. It is home to Ibrahim Babangida and Abdulsalami Abubakar, two of Nigeria's former military rulers. The Nupe, Gbagyi, Kamuku, Kambari, Dukawa, Hausa and Koro form the majority of numerous indigenous tribes of Niger State.
Niger Delta
The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate. The core Niger Delta later became a part of the eastern region of Nigeria, which came into being in 1951 (one of the three regions, and later one of the four regions). The majority of the people were those from the colonial Calabar and Ogoja divisions, the present-day Ogoja, Annang, Ibibio, Oron, Efik, Ijaw and Ogoni peoples. The National Council of Nigeria and Cameroon (NCNC) was the ruling political party of the region. The NCNC later became the National Convention of Nigerian Citizens, after western Cameroon decided to separate from Nigeria. The ruling party of eastern Nigeria did not seek to preclude the separation and even encouraged it. The then Eastern Region had the third, fourth and fifth largest indigenous ethnic groups in the country including Igbo, Efik-Ibibio and Ijaw.
