The Citizenship Amendment Act (CAA), 2019, in India was widely contested by both political parties and various civil society formations. Shaheen Bagh, a sit-in protest demonstration which continued for over a hundred days in the nation’s capital from mid-December 2019 to late March 2020, occupied the central position within the corpus of these protest demonstrations. The protests at Shaheen Bagh were led by poor, Muslim working-class women, who had come out on the streets protesting and asserting their rights amidst the dominant ruling-class communal politics. The Shaheen Bagh protests were a potent force of the working-class and oppressed minorities of the country. The paper brings in Marxist and Gramscian perspectives to explain how Shaheen Bagh has contributed to Indian left-wing politics. The paper argues that the women in Shaheen Bagh have been successful in bridging the gap between the civil society and political society in the country and has to an extent, altered the very nature of Indian politics. Moreover, the assertive nature of the Muslim women regarding their religion and the support which they garnered from the Indian left, widely accused by many of being Islamophobic in nature, has wide repercussions as far as political and social alliances between the left and Muslim politics in India is concerned. The present paper locates the protest within the notion of subaltern unity and tries to analyse the possible impacts of the support for the protests, within and beyond the anti-CAA protest movement, from the Indian left.
