Northeast India is home to numerous ethnic communities. Considered a marginal geographical space, this region is as diverse as India itself in terms of its languages, cultures, and ethnicities. However, the dominant tendency is to conceptualise the Northeast as a singular, homogenous territory, and this problematic construction both implies a shared identity among different ethnic communities and determines the way the region is governed by the Indian state. Identity and Marginality in Northeast India rectifies this construction and highlights the heterogeneity of the different groups and their unique experiences, contestations, and conflicts.
