Final answer:
Britain ruled Nigeria through local rulers and tribal chiefs in a system known as indirect rule.
Step-by-step explanation:
The statement that Britain ruled Nigeria through local rulers and tribal chiefs in a system known as indirect rule is true.
Indirect rule was a colonial administration strategy employed by the British Empire in various parts of its African colonies, including Nigeria. Under this system, the British maintained control by working with existing local power structures and allowing Indigenous rulers and tribal chiefs to exercise some authority in the administration of their territories.
This approach helped the British achieve their colonial objectives while minimizing direct interference in local affairs and maintaining the cooperation of the Indigenous elites.
