Concept:Indirect rule works best where there is a centralized traditional authority that can be used to govern. Eastern Nigeria lacked such a system.
Explanation:Before the arrival of the British, most communities in Eastern Nigeria had a fragmented and decentralized political structure.
There were no powerful, recognized kings or paramount chiefs like the Hausa emirs or Yoruba obas.
Consequently, the system is often described as acephalous, meaning "without a head" or without a single political leader.
Because there was no central authority, the British had no traditional ruler to rely on for indirect rule.

Thus, the fundamental cause of failure was the absence of a centralized political framework, not the conduct of any one chief or taxation policy.
