The notion of home and belonging in the highlands of India’s northeastern region in the post-independence period is shaped by the colonial spatial knowledge and the ethnicization of shared spaces for administrative convenience. The persisting ethnic-territoriality in the region, which is mainly fueled by the demand for exclusive ethnic homelands in a territory co-inhabited by different ethnic groups, results in conflicts. Such ethnic conflicts have led to displacements not only within the national border but even beyond, where border crossing is a quotidian experience for people that inhabited both sides of the largely porous international borders. In such situation shared spaces become contested spaces and each engaging in questioning the indigeneity of the other. This politics of belonging and indigeneity in the region is pursued with rigour and intensity to mainly ensure ethnodomination or to achieve exclusive ethnic homeland in such contested spaces today.
