Royal Consorts#
Kogi holds three distinct consort traditions in one state. In the Igala kingdom the *Attah*'s senior wife is styled Oma Attah, and the older female office is the Achadu's counterpart, the *Ogbe*, in the nine-clan Igala Mela council which alone can install an Attah. In the Ebira federation the *Ohinoyi*'s consort holds no crowned office, authority among women running through the *ekuechi* masquerade calendar and the clan (*ekura*) women's heads. In the Okun Yoruba west (Kabba, Ijumu, Yagba, Owe) the Yoruba pattern applies in full: the crowned Oba's wife is an Olori, and a separate Iyalode holds market jurisdiction.
