The Nagas are a conglomeration of several tribes inhabiting the North Eastern part of India, primarily in Nagaland, and north-western Burma. The Naga people traditionally are tribally organized, with a strong warrior tradition. Their villages are sited on hilltops and until the later part of the 19th century, they made frequent armed raids on the plains below and on neighbouring tribes. Headhunting ceased with the advent and spread of Christianity, which also has resulted in tremendous change in the Naga culture. In the classless, caste-less Naga society, women have traditionally enjoyed a high social position, with a pivotal role in both family and community affairs.
