In 1941 the Third Party Conference of the Communist League of India changed its name to Communist Party of India (not to be confused with its far more well-known namesake). In March 1943 the name RCPI was adopted, in order to differentiate itself from the CPI. The party positioned itself claiming to be the sole true leftist party in the country, denouncing all other left forces as ideologically bankrupt. Overall RCPI avoided collaboration with other left-wing groups. RCPI labour organizing was done largely outside the All India Trade Union Congress. It managed to build a core of political cadres and was active building a labour movement amongst workers at the jute mills in the Beliaghata-Narkeldanga area of Calcutta. The party was often referred to as the 'Tagorites' or as the '"Ganavani" group' (after the name of its publication).
