The Igbo people (formerly Ibo; Ṇ́dị́ Ìgbò in the Igbo language) are an ethnic group of southeastern Nigeria. They speak Igbo, which includes various Igboid languages and dialects; a majority of them also speak Nigerian English. Igbo people are one of the largest and most influential ethnic groups in Nigeria.
In rural areas in Nigeria, the Igbo are mostly farmers. Their most important crop is the yam; celebrations are held annually to celebrate its harvesting. Other staple crops include cassava and taro.
Before British colonialism, the Igbo were a politically fragmented group. There were variations in culture such as in art styles, attire and religious practices. Various subgroups were organized by clan, lineage, village affiliation, and dialect. There were not many centralized chiefdoms, hereditary aristocracy, or kingship customs except in kingdoms such as those of the Nri, Arochukwu, Agbor and Onitsha. This political system changed significantly under British colonialism in the 19th century; Eze (kings) were introduced into most local communities by Frederick Lugard as "Warrant Chiefs". The Igbo became overwhelmingly Christian under colonization. Chinua Achebe's Things Fall Apart is one of the most popular novels to depict Igbo culture and changes under colonialism.
