Concept:The Igbo resisted British rule because their society had no centralised authority, making indirect rule difficult to apply.
Explanation:The Igbo operated an acephalous political system, meaning they had no single king or chief.
British indirect rule relied on appointing local chiefs to govern.

This led to widespread resistance against colonial rule.
Therefore, the key reason is the egalitarian nature of Igbo society, not taxation or favouritism.
