The Igbo people (English: /ˈiːboʊ/ EE-boh, US also /ˈɪɡboʊ/ IG-boh; also spelled Ibo and historically also Iboe, Ebo, Eboe, Eboans, Heebo;natively Ńdị́ Ìgbò) are an ethnic group found in Nigeria, Cameroon, Gabon, and Equatorial Guinea. Their primary origin is found in modern-day Abia, Anambra, Ebonyi, Enugu, and Imo States, while others can be found in the Niger Delta and along the Cross River. The Igbo people are one of the largest ethnic groups in Africa.

The Igbo language is part of the Niger-Congo language family. Its regional dialects are mutually intelligible amidst the larger "Igboid" cluster.The Igbo homeland straddles the lower Niger River, east and south of the Edoid and Idomoid groups, and west of the Ibibioid (Cross River) cluster.

The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone.

The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil. The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate.
