A party of revolutionaries, forged in the struggle against colonial rule and committed to a socialist India.
The Revolutionary Socialist Party was founded on 19 March 1940. Its founders came from the Anushilan Samiti and the Hindustan Socialist Republican Army, armed revolutionary groups of the freedom movement. Many of them spent long years in British prisons and the Cellular Jail, where they studied Marxism and turned towards organised working-class politics.
Tridib Chaudhuri is recognised as a founder of the party, and Jogesh Chandra Chatterjee served as its first General Secretary from 1940 to 1953. From Bengal the party spread to Kerala, Tripura and other states, building trade unions, peasant associations and student and youth movements.
We analyse society through class struggle and work for the emancipation of the working class.
A society free of exploitation, where the wealth created by labour serves the people who create it.
From the start our founders rejected the Comintern line and 'socialism in one country', criticising Stalin's leadership without turning to Trotskyism.
Working with the Left and democratic forces to defend secularism, federalism and the Constitution.
