The other two groups are found in other parts of Africa. The Igbo are found only in Nigeria. Their achievements have been significant in such fields as art, agriculture, politics, economics, and, above all, education, both in Nigeria and on the African continent. .
The language of the IGBO is also called IGBO. It is a member of the Kwa language subfamily of West Africa, which was developed as a separate language about 4,500 years ago. However, the language remained unwritten until the later 19th century, when the British colonists established mission schools and churches. The missionaries developed the IGBO orthography that enabled them to translate the Bible into IGBO.
The community of IGBO are people who are descendents of one or more male ancestors. These ancestors are usually the founders of the village. The village begins as a nuclear family or one man and one or more wives, who live in the same household, the OBI. As the male children grow and multiply, they build their own separate households in the same area. These families, umunna, in turn, multiply and become a bloc, villages into clans, many of which combine to form Igboland. The marriage institution is patrilocal, which means that a married couple must live in the husband's home or compound. If there is a divorce, the women is the one to leave the house and return to her parents" home or her birthplace. Also, family sccession is patriarchal, meaning that the father is the head of the family, and descent is traced through the male line.
As a result of Igbo's world view, their religious life influences their secular life very much. They pour libations of wine, break kola nut, and say incantations to invite the ancestors and the unborn babies-"spirit beings"- to their meals and meetings. Because of the presence of such spirit beings, every living person is careful about what he or she does or says. At the end of the meeting, the decision that the people make is binding on everybody.
