In the Superior Police Services (later- Imperial Police Services), when the British government introduced the Indian Council Act 1861, the rank of the IG was the senior-most rank. The main purpose of the Indian Council Act of 1861 was to change the executive system of governance in India into a cabinet run on a portfolio system.

To add to this, in the same Indian Council Act 1861, the Imperial Police Services, a new cadre of police, was created. This Imperial Police was also part of the police force at the time, which was known as the Indian Police Services. This cadre was created after the First War of Independence in 1857.
