This paper critically examines the ritualistic performance of Deodhani in Assam as a rich cultural archive that embodies precolonial understandings of gender plurality and sacred non-normative identities. Often overlooked in dominant gender and historical discourses, the Deodhani tradition, where individuals, often assigned female at birth but not exclusively so, embody the goddess through trance and dance, offers a significant departure from rigid colonial binaries of gender. By positioning Deodhani within a larger South Asian matrix of ritual-based gender variance, this paper interrogates how indigenous epistemologies once accommodated diverse gendered and spiritual experiences beyond the man-woman binary. Drawing on oral histories, ethnographic accounts, and comparative cultural studies, particularly of the Jogappas of Karnataka and the Aravanis of Tamil Nadu, this paper maps the broader contours of transgenderism in India. Furthermore, it investigates how colonial ethnography, moral reform movements, and postcolonial nation-building contributed to the marginalization and pathologization of such traditions. In reclaiming Deodhani as a precolonial site of gender fluidity and divine embodiment, this paper not only recovers suppressed histories but also critiques the epistemic violence embedded in modern gender constructions. The paper also advocates for a more inclusive historiographical lens that honours ritual, spirituality, and indigenous gender plurality as legitimate modes of historical knowledge.
