Revolutionary Socialist Party (RSP) is a communist party in India. The party was founded on 19 March 1940 by Tridib Chaudhuri and has its roots in the Bengali liberation movement Anushilan Samiti and the Hindustan Socialist Republican Army. The party got around 0.4% of the votes and three seats in the Lok Sabha elections in 1999 and 2004. It is part of the Left Front (West Bengal), Left Front (Tripura) and Congress-led United Democratic Front (Kerala). History Development of Anushilan Marxism A major section of the Anushilan movement had been attracted to Marxism during the 1930s, many of them studying Marxist–Leninist literature whilst serving long jail sentences. A minority section broke away from the Anushilan movement and joined the Communist Consolidation, and later the Communist Party of India. The majority of the Anushilan Marxists did however, whilst having adopted Marxist–Leninist thinking, feel hesitant over joining the Communist Party. The Anushilanites distrusted the political lines formulated by the Communist International. They criticised the line adopted at the 6th Comintern congress of 1928 as 'ultra-left sectarian'. The Colonial theses of the 6th Comintern congress called upon the communists to combat the 'national-reformist leaders' and to 'unmask the national reformism of the Indian National Congress and oppose all phrases of the Swarajists, Gandhists, etc. about passive resistance'. Moreover, when Indian left-wing elements formed the Congress Socialist Party in 1934, the CPI branded it as Social Fascist. When the Comintern policy swung towards Popular Frontism at its 1935 congress, at the time by which the majority of the Anushilan movement were adopting a Marxist–Leninist approach, the Anushilan Marxists questioned this shift as a betrayal of the internationalist character of the Comintern and felt that the International had been reduced to an agency of Soviet foreign policy. Moreover, the Anushilan Marxists opposed the notion of 'Socialism in One Country'. However, although sharing some critiques against the leadership of Joseph Stalin and the Comintern, the Anushilan Marxists did not embrace Trotskyism. Buddhadeva Bhattacharya writes in 'Origins of the RSP' that the "rejection of Stalinism did not automatically mean for them [the Anushlian Samiti] acceptance of Trotskyism. Incidentally, the leninist conception of international socialist revolution is different from Trotsky's theory of Permanent Revolution which deduces the necessity of world revolution primarily from the impossibility of the numerically inferior proletariat in a semi-feudal and semi-capitalist peasant country like Russia holding power for any length of time and successfully
