North-East India refers to the easternmost region of the Republic of India. Geographically and culturally, the region now called north-east India is situated between the two traditions of Indic Asia and Mongoloid Asia and is regarded as part of Southeast Asia. This geographical-cultural condition of "in-betweenness" is an important factor in the area’s crisis of identity. The leaders of the present-day "underground outfits" continue to struggle for independence, as the political integration of the northeast to India was brought about without the approval of its people. The people of northeast India, who are culturally Mongoloid, refuse to accept the caste-ridden social system advocated by ‘Indian’ culture. Similar struggles for independence are also going on in other northeastern subdivisions or sister regions, such as Assam, Manipur, Mizoram, Meghalaya and Nagaland.
