N.K.Das. Ethnic Identity Ethnıcıty And Social Stratification In North-East India. Delhi, Inter-India Publications, 1989.

The study of nascent socio-political formations in the North-East is a subject of enormous significance to social scientists and political strategists alike. It has been a frontier region of India's history and culture where scholars like K.L. Barua, S.K. Bhuiyan and J.H. Hutton have tried to identify the structures and processes that are relevant to the understanding of social situations elsewhere in the country. Over the years scholars have been able to reconstruct the outlines of political history and ideological super-structure of the social processes that have been at work. In recent years the process of state formation in North-East India has been critically analysed.
