The word "
Naga" is used as a collective term for several ethnic tribes living on the Himalayan Range in
Northeast India, which were brought under the control of
British India during the 19th century. After India's independence, several Naga leaders tried to secede from India. In 1975, the separatist
Naga National Council (NNC) renounced violence and signed the
Shillong Accord with the
Government of India. Some of the NNC leaders disapproved of this peace treaty: these leaders included
Isak Chishi Swu of the
Sumi (Sema) tribe,
Thuingaleng Muivah of the
Tangkhul tribe, and
S. S. Khaplang. These leaders broke off from the NNC and formed the National Socialist Council of Nagaland (NSCN) as a new separatist organisation. NSCN formed an underground Naga Federal Government having both civil and military wings, the Government of the People's Republic of Nagalim (GPRN), and the
Naga Army. Later, a disagreement surfaced within the group's leaders over the issue of commencing dialogue with the Indian government. On 30 April 1988, the NSCN split into two factions; the NSCN-K led by Khaplang, and the NSCN-IM, led by Chishi Swu and Muivah. The split was accompanied by a spate of violence and clashes between the factions. In 1997, ceasefire agreements were made between the factions of the NSCN and India. Later, NSCN-K abrogated the ceasefire agreement. On 6 April 2015, a new faction of the NSCN was formed. Y. Wangtin Konyak and P. Tikhak officially announced the formation of a new Naga political group going by the name "National Socialist Council of Nagaland (Reformation)" or NSCN-R. The decision came after Konyak, a senior minister, or Kilonser, of the NSCN-K and a personal secretary to founder Khaplang was expelled from the group after disagreements over its ceasefire agreement. The NSCN-R, wanted to continue with the ceasefire maintaining that "violence has never served a good purpose and the Naga political problem can only be resolved through peace and negotiation" while Khaplang had it abrogated because the "14 years of ceasefire between NSCN-K and India has become a mockery and futile exercise." Opposed to militant activities, the primary agenda of the NSCN-R would be to "develop a sense of brotherhood among the Naga family and to rebuild the trust and faith among the Naga society." On 3 August 2015, NSCN-IM leaders Isak Swu and T. Muivah signed a
framework agreement for peace with the Government of India in the presence of Prime Minister
Narendra Modi, Home Minister Rajnath Singh, and National Security Advisor Ajit Doval. Also in 2015, NSCN-K became affiliated with a militia organization named the
United Liberation Front of Western South East Asia (UNLFW), a
united front of Northeast Indian militant groups, and shortly after broke off peace talks with the Indian government. The UNLFW carried out the
2015 Manipur ambush, in which 18 Indian soldiers were killed and 15 were wounded. == Factions ==
