Concept:In the Igbo traditional political system, the highest democratic body was the assembly that represented the whole community.
Explanation:The highest democratic institution among the Igbo was the Oha-na-eze.
This was a general assembly of the people and their recognised leaders.
It brought together representatives from different lineages and villages.
The Oha-na-eze made laws, declared war, made peace, and settled major disputes.
It also served as a check on the powers of the Eze, chiefs, and other title holders.
The Umunna was only the council of immediate kinsmen within a family group.
The Umuada was the association of daughters of the lineage, important but limited in scope.
The Ofo Title Holders were mainly ritual and religious authorities.
These bodies represented sections of the community, not the entire people.
Only the Oha-na-eze was broad enough to be described as the highest democratic institution.
It ensured that governance was carried out with the consent and participation of the people.
