What political party did Netaji Subhash Chandra Bose establish?

Subhash Chandra Bose established the All India Forward Bloc(AIFB). It developed as a faction within the Indian National Congress as a group of young, radical left-wing nationalists back in 1939.

As its leader, Subhash Chandra Bose sought to remove the British from India with the help of the Axis Powers during WW2. On June 22, 1940, the party met in Nagpur and declared itself as a socialist party. The AIFB organized the first members of the Indian National Army and led an armed struggle against the British with the help of the Japanese which ended with the capture of Singapore by the British and the death of Bose in 1945.

The party was re-established after India's independence.
