During World War-II, 'Home Guards' - a voluntary citizen organisation for local defence was raised in the United Kingdom. In India, in December 1946, Home Guards were raised in Bombay to assist the Police in controlling civil disturbances and communal riots. Subsequently, this concept of a voluntary citizens force as auxiliary to the Police for maintenance of law and order and for meeting emergencies like floods, fires, famines etc was adopted by several other States. In the wake of Chinese aggression in 1962, the Centre advised the States and Union Territories to merge their existing voluntary organisations into the all-India force known as 'Home Guards' which would be voluntary both in concept and character.
