There are seventeen Naga tribes in Nagaland, the Northeastern Indian province which straddles the boarder with Myanmar. They were encountered by the British in the 19th century and one tribe (the Angami) inflicted a famous victory on British forces at the Battle of Khonoma in 1879. These tribes were largely left alone by the British until the invasion of India via Nagaland by the Japanese in 1944. The Nagas supported the British in that conflict and were fighting with the British at the famous battle of Kohima in 1944. Until the 1960s a lot of Nagaland remained remote and tribal, yet the arrival of Baptist missionaries slowly converted the Naga tribes. By the late 1980s most of their animistic beliefs and the practise of headhunting ceased, but a bitter war for independence still ranged with the Indian Government. In 2004 just before a state wide ceasefire, the Hornbill festival was founded. This is a sort of Naga festival of festivals which is held every December. The Chang tribe from the Eastern Nagaland town of Tuensang is one of the participants.
