The Central Reserve Police Force (CRPF) is a central armed police force in India under the Ministry of Home Affairs. The CRPF assists states and Union Territories in maintaining law and order and internal security. It is composed of the Central Reserve Police Force (Regular) and Central Reserve Police Force (Auxiliary).

It was established on 27 July 1939 as Crown Representative’s Police with the objective of providing security to the British Crown Representatives in India. The force was later renamed as the Central Reserve Police Force by an Act of Parliament in 1949. The CRPF played a major role in the Parliamentary elections of September 1999.^[3]

The Central Reserve Police Force (CRPF) is the largest paramilitary force in India, comprising 247 battalions and exceeding a total strength of 301,376 personnel as of 2019.^[4] CRPF officers are also deployed in United Nations missions.

Originally constituted as the Crown Representative Police in 1939, CRP was raised in response to the political unrest and agitations in the then Princely States of India following the Madras Resolution of the All-India Congress Committee in 1936 and the ever-growing desire of the Crown Representative to help the vast majority of the native States preserve law and order as part of imperial policy.

After Independence, the force was renamed the Central Reserve Police Force by an Act of Parliament on 28 December 1949. This Act constituted CRPF as an armed force of the Union. Sardar Vallabhbhai Patel, the then Home Minister, visualised a multi-dimensional role for it in tune with the changing needs of a newly independent nation. The force played a significant role during the amalgamation of the princely States into the Indian Union. It helped the Union Government discipline the rebellious princely State of Junagadh and the small principality of Kathiawar in Gujarat which had declined to join the Indian Union.

During the early 1950s, the performance of the CRPF detachments in enforcing law and order in Bhuj, the then Patiala and East Punjab States Union and Chambal ravines was appreciated by all quarters.

On 21 October 1959, SI Karam Singh and 20 other CRPF personnel were attacked by the Chinese Army at Hot Springs in Ladakh resulting in 10 casualties. The survivors were imprisoned. Since then, 21 October has been observed as Police Commemoration day nationwide, across all states in India.^[5]

In the late 50s and early 60s, contingents of the CRPF were sent to Kutch, Rajasthan, and Sindh borders to check infiltration and trans-border crimes. They were, subsequently, deployed on the Pakistan border in Jammu and Kashmir following attacks launched by the Pakistani infiltrators.

During the Sino-Indian War of 1962, the Force once again assisted the Indian Army in Arunachal Pradesh. Eight CRPF personnel were killed in action. In the 1965 and 1971 Indo-Pak wars also the Force fought shoulder-to-shoulder with the Indian Army, both on the Western and Eastern borders.

For the first time in history, thirteen companies of CRPF were airlifted to join the Indian Peace Keeping Force in Sri Lanka to fight the militant cadres. Besides, CRPF personnel were also sent to Haiti, Namibia, Somalia, and Maldives to deal with the law and order situation there, as a part of the UN Peacekeeping Force.

In the late seventies, when extremist elements disturbed the peace in Tripura and Manipur, CRPF battalions were deployed in strength. Simultaneously, there was turmoil in the Brahmaputra Valley. The CRPF had to be inducted in strength not only to maintain law and order but also to keep lines of communication free from disruption. The commitments of the Force continue to be very high in the Northeast in dealing with the insurgency
