Inter-caste marriages in India continue to face social resistance despite constitutional support and legal provisions like the Special Marriage Act, 1954. Deep-rooted caste hierarchies and traditional norms make such unions a matter of familial and communal concern rather than personal choice. This research paper examines the critical role of families and communities in shaping the acceptance or rejection of inter-caste marriages. While urban areas show increasing tolerance due to education, media exposure, and changing values, rural communities often respond with strong opposition, including emotional pressure, social boycott, and, in extreme cases, honour-based violence. The study incorporates sociological theories and real-life case studies to understand the dynamics of caste, family honour, and social status. It also evaluates the role of legal frameworks, government incentives, and civil society in promoting social change. Overall, the paper reflects on the ongoing tension between tradition and modernity in India's evolving social fabric.
