Solidarity plays a crucial role in supporting survivors of Gender-Based Violence (GBV), enabling them to reclaim their self-esteem amidst the disruptions caused by such violence. However, working on GBV is challenging for grassroots organizations in patriarchal societies. This paper explores the role of solidarity in feminist organizing for fighting against GBV in India. Through qualitative engagement with a women’s courts in India— an all-women organization functioning as a quasi-judicial forum in rural regions— the paper explores how solidarity is crafted at the grassroots level to combat GBV and how feminist dialoguing with solidarity helps women come together by valuing their shared vulnerability. The findings highlight how solidarity emerges as a unifying force among participants, originating from their shared vulnerability due to their gendered experiences in postcolonial society. Building on postcolonial feminist literature, the study brings insights into the communicative engagement practices of grassroots feminist organizations and the critical role of affect in developing solidarity for feminist causes.
