Between 2014 and 2022, the Bharatiya Janata Party (BJP) made a determined bid to establish its electoral and discursive dominance in regions beyond its traditional strongholds in Northern and Western India. In the North-east, in the Christian-majority states of Mizoram, Meghalaya, and Nagaland, it encountered fierce hostility from the Church which exercised a hegemonic control over the religious, social, and political life in these states. This article focuses on the political tussle between the BJP and the Church in this time period and attempts to explore the deeper ideological contestations and competing narratives underlying this struggle and their implications for the Indian political discourse. These include contestations over the very conceptualization of secular democracy in India and the role of religion in it; different understandings of religious conversions and freedom of conscience; and the conflicting agendas around the categories of ‘tribe’, ‘indigenous people’/‘adivasi’, and ‘janjati’/‘vanvasi’.
