'Prati Sarkar' was active during the period of 1943-1946. This was a term used to refer to the underground government or parallel administration that emerged during the Quit India Movement of 1942. It operated in various parts of India and was engaged in acts of civil disobedience and resistance against British colonial rule. The Quit India Movement, also known as the August Movement, was launched by Mahatma Gandhi in August 1942 to demand an end to British rule in India. The movement gained momentum and led to the emergence of underground governments in some areas, one of which was referred to as 'Prati Sarkar.' The movement and the underground activities continued beyond 1942, hence the period being 1943-1946.
