The Central Reserve Police Force also known as CRPF is a paramilitary security agency/Force functioning under the aegis of Ministry of Home Affairs(MHA), Government of India. The CRPF's primary role lies in assisting the State/Union Territories in police operations to maintain law and order and contain insurgency. It came into existence as the Crown Representative's Police on 27 July 1939. After Indian Independence, it became the Central Reserve Police Force on enactment of the CRPF Act on 28 December 1949. Besides Law and Order and counter-insurgency duties, the role of CRPF in the General Elections, held repeatedly during the past few years, has been very significant and vital. This is especially true for the trouble-ridden states of J&K, Bihar and in the North East. During the Parliamentary elections of September 1999, the CRPF played a major role in the security arrangements. The CRPF is the largest paramilitary force in the world with 210 battalions besides various establishments. Of late, CRPF contingents are also being deployed in UN missions.
