Concept:Indirect Rule was adopted because the British could govern through existing traditional rulers and local institutions.
Explanation:The British lacked enough personnel and funds to administer the colonies directly.

This made the existing system of governance and taxation useful for colonial control.
Thus, the presence of an efficient tax system and organised native administration encouraged its adoption.
