Indian Imperial Police

The Indian Imperial Police, (officially known as the Imperial Police or I.P.) was part of the uniform system of police administration in British Raj, as established by Government of India Act 1858 and Police Act 1861. It was motivated by the danger experienced by the British during the 1857 Revolution.

In 1920, the Imperial Indian police had 310,000 police in their contingent. Its members policed more than 300 million people from the Raj (now India, Pakistan, Bangladesh and Burma).

In 1948, a year after India's independence, the Imperial Police Service was replaced by the Indian Police Service, which had been constituted as part of the All-India Services by the Constitution.
