Nri-Igbo

Nri is an Igbo city-state in Anambra State, Nigeria. It was the seat of a powerful and imperial state who was influenced much by the territories inhabited by the Igbo of Awka and Onitsha to the east; the Efik, the Ibibio, to the south; Nsukka and Asaba, and the Anioma to the west. Today, Nri claims to be the heart and origin of the Igbos, but it is historically dated that Igbo Ukwu, formally known as Igbo, and Igbo Nkwo is the true origin and beginning of the Igbos.

History
The Nri clan existed from as far back as the 9th century. Nri (the founder of Nri clan) and Aguleri were two of the sons of Eri (founder of Aguleri) and had migrated to the present day Nri from the Anambra (Omambala) river valley (Eriaka) in Aguleri in Northern Igboland. Nri was said to have inherited spiritual powers from his father. The Nri people belong to the Umueri clans who trace their origins to Eri.

Mythological Origin
In the Nri mythology, Nri sent by Chukwu to make peace (settle disputes and cleanse abominations) and provide Igbo people food (yam and cocoyam).
