The main focus of the present treatise to understand the role of anthropologists towards nation building through the evaluation of Manipur Unrest from the existing published empirical study materials of anthropology and the literature on International diplomatic relations in order to maintain India's sovereignty. The vulnerable land mass of our country--the Chicken neck, which is commonly known as Siliguri Corridor, is not only a corridor and gateway to North-east India as well as South -East Asia but it is also vital in view of our country's security point of view, keeping integral sovereignty. Within this land mass number of tribal ethnic groups who were chiefly emigrated here from the adjoining nations before the colonial administration with their distinct cultural attributes are living in a distinct territorial enclave with full of cultural diversity like bi-liny, matriliny, phratry, moiety, binary system, polyandry Zeliangrong, Donyi-poloism, Buddhism, Bon religion etc., this treasure island may attract any anthropologist to explore such treasures. More so, these tribal communities are living close to international border (LAC) of other nations. In this landscape of cultural pluralism where each ethnic community not only restricted to a particular niche for eke out their sustainable activities but also maintain a distinct cultural identity by practicing a distinct social structure, marital alliances, rituals etc.
