Concept:Igbo political organization was decentralized, which made it difficult for any single ruler to exercise autocratic power.
Explanation:In pre-colonial Igboland, there was no central authority or paramount chief.
The Igbo system was republican, acephalous, and highly democratic.
Power was shared among several traditional institutions instead of being concentrated in one person.
These institutions included the village assembly, council of elders, age grades, and Ozo title holders.
Others were the priest of deities, masquerade societies, cult groups, and Umuada.
Each group had its own role and influence, which limited the power of any individual leader.
Because leadership was spread across these bodies, no ruler had the absolute power needed for autocratic rule.
This decentralized arrangement therefore made autocratic government very difficult to establish in Igboland.
