The king (Attah of Igala) was supreme and was assisted by a council o; elders.
The council in question checkmates the powers of the Attah. The Ashadu was also important in the Igala government.
Again, the Abokko, Agaidoko and Omogboye were responsible for the trade in the riverine areas of Igala.
The vassal states in Igala land were Igbira and Idoma. And thus, their chiefs were equally confirmed by the Attah. Consequently, they pay tribute to the Attah.
Moreover, the Igala people exercised both cultural and political control over their neighboring towns – Oworo, Ikiri, Ijumu, Yoruba towns, Onitsha and others.
