Illah is said to have been founded by Ala[.] […] One of the traditions holds that Ala’s father, lka, came from Nteje (some informants say he came from Nri) and the mother, Ejini, came from lgalaland. […] While at Omorka, the Anam/Nzam people from the east of the Niger frequently harassed the Illah. Through the assistance of a later immigrant, an Edaiken (Oba's first son) from Benin, the Illah contained the Anam's menace. […] The Asaba and Illah traditions seem to indicate a fusion of Igbo and Igala migrants, and emphasize the age-long relationship between them and the Igala in the north and the Igbo in the east.
