Examining the Marathi translation of The Communist Manifesto published in 1931 and situating it in the socio-historical context of workers’ movements in Mumbai in the 1920s and 1930s, this paper argues that the so-called subordinated classes engaged with it and created a workers’ public that was in conversation with the elite public sphere. But it holds that the vernacular version had to navigate the structures of language and a social structure in which caste was an important feature to make itself comprehensible to other intellectuals, trade union leaders and workers.
