and are also followers of the religious teachings of Sheikh Usman dan Fodio. Igbo culture The Igbo people, commonly and often referred to as Ibo people, are one of the largest ethnic groups to ever exist in Africa; they have a total population of about 20 million people. Most people who are a part of this ethnic group are based in the southeastern part of Nigeria, they contribute to about 17 percent of the country's population. They can also be found in large numbers in Cameroon and other African countries. It is believed that the Igbo people originated in an area that is about 100 miles north of their current location at the confluence of the Niger and Benue Rivers. The Igbo people share linguistic ties with their neighbours the Bini, Igala, Yoruba, and Idoma, with whom it is believed they were closely related until five to six thousand years ago. The first Igbo in the region may have moved onto the Awka-Orlu plateau between four and five thousand years ago. The eastern part of Nigeria is the home of the Igbos, who are mostly Christians. Their traditional religion is known as Omenani/Omenala. Both concepts, each an aspect of a single whole, aspire to protect and preserve the purity, sanctity and sacredness of the land and the people therein. 'Omenana' is man-made; it is easily changed and is adaptable. 'Odinana', on the contrary, is a code of life, handed down from Chukwu, God the Creator, to Eri, the patriarch of the Igbo race, to prevent chaos and confusion. The earth spirit, Ana, is 'odinana', as is the sacred role of yam in the Igbo world, the right of inheritance, and the place of the elder. 'Odinana', as the immutable customary rites and traditions of the Igbo world, is enduring and cuts across indigenous Igbo people, while 'omenana' is rather relative from one section of the Igbo to the other. Socially, the Igbos are led by monarchs who had limited power historically. These figures are expected to confer subordinate titles upon men and women that are highly accomplished. This is known as the Nze na Ozo title system. Ijaw culture The Ijaw people are said to be a collection of people that are native to the Niger Delta area in Nigeria. Owing to the affinity they have with water, a significant number of the Ijaw people are discovered as migrant fishermen
