<p>Religious belief systems play a crucial role in human social life, uniting communities and providing a sense of belonging. The recent tribal movement in Jharkhand, known as “Sarna Dharma” or “Adi Dharma,” seeks a separate religious code in the decadal census of India to legitimize their tribal beliefs, ensuring recognition and protection of their unique cultural practices and beliefs. Tribal communities worship nature or ancestors and believe in supernatural powers, but conversion and social suppression often influence their religious choices. The Jharkhand state assembly passed the “Sarna Bill” in November 2020, marking a significant step forward in this movement. Tribal religions are deeply connected to their ecology and culture, which is disturbed by the onslaught of otherworldly structured religions. The demand for a separate religious code for their age-old “Sarna Dharma” is an endeavor by the tribals of Jharkhand. This research aims to comprehensively examine the ‘Sarna’ religion and its unique attributes, analyze the historical connection between humans and nature, investigate the relationship between different tribal communities, and understand the tribal religious identity. The significant findings highlight the power of the tribal movement for religious identity and the urgent need for environmental preservation. This paper explores how the construction of tribal religious identity fuels resistance against established or mainstream religions, using Ted Gurr’s reformative movement within the framework of deep ecology philosophy. The ethnographic study will use multiple theories to explain the idea of tribal religion and how the syncretic nature of religious identity influences this socio-religious movement.</p>
