NSCN-IM

The NSCN-IM — the Isak-Muivah faction of the National Socialist Council of Nagaland — is the principal armed organisation in India's longest-running insurgency, rooted in the Naga demand for sovereignty articulated since A. Z. Phizo's Naga National Council (NNC) declared independence on 14 August 1947, one day before India's own. The NNC organised a plebiscite in 1951 claiming overwhelming support for independence and boycotted the first Indian general elections. After the NNC's collapse following the Shillong Accord of 11 November 1975 — which a faction rejected as a surrender — Isak Chishi Swu, Thuingaleng Muivah and S. S. Khaplang founded the NSCN on 31 January 1980. Ideological and ethnic fissures split the group on 30 April 1988, producing the NSCN-IM (led by Swu and Muivah, drawing strength from the Tangkhul Nagas of Manipur) and the NSCN-K (led by Khaplang). The NSCN-IM espouses a blend of Naga nationalism and socialism under the slogan "Nagaland for Christ," and demands Greater Nagalim, a unified homeland incorporating Naga-inhabited areas of Manipur, Assam, Arunachal Pradesh and Myanmar.

The trajectory from armed conflict toward negotiation began when the NSCN-IM and the Government of India concluded a ceasefire agreement that took effect on 1 August 1997, suspending offensive operations and counter-insurgency sweeps against the faction. The ceasefire is governed by mutually agreed Ceasefire Ground Rules, monitored through a Ceasefire Monitoring Group and a Joint Monitoring Group, and is renewed periodically. Designated camps were established where cadres could be stationed with their weapons, separating the political dialogue from field operations. Successive Indian government interlocutors — beginning with Swaraj Kaushal and continuing through K. Padmanabhaiah and later R. N. Ravi — held more than a hundred rounds of talks, many conducted abroad in Bangkok, Amsterdam, Geneva and Zurich, reflecting the leadership's long exile.

The substantive breakthrough came on 3 August 2015, when Prime Minister Narendra Modi's government and the NSCN-IM signed a Framework Agreement in New Delhi, with Muivah present and interlocutor R. N. Ravi as signatory. The text remained confidential, but the government characterised it as recognising the unique history and identity of the Nagas while affirming a settlement within the Indian Union. The NSCN-IM read the agreement as conceding "shared sovereignty" and a degree of pan-Naga integration; New Delhi rejected interpretations implying a separate flag or constitution. To broaden the process, the government brought seven other groups together as the Naga National Political Groups (NNPGs), which signed an Agreed Position in November 2017, creating a parallel and sometimes competing track to the IM channel.

Talks subsequently stalled over the NSCN-IM's two non-negotiable demands: a separate Naga flag (the Raised Spear) and a separate Naga constitution (the Yehzabo). Relations between the IM and interlocutor R. N. Ravi — who concurrently became Governor of Nagaland in 2019 — deteriorated sharply, with the IM publicly accusing Ravi of altering the Framework Agreement's wording. A. Z. Jami and other functionaries issued statements through Hebron, the NSCN-IM's general headquarters near Dimapur. Isak Chishi Swu died in 2016, leaving Muivah, born in 1934 in Somdal village, Ukhrul district, Manipur, as the dominant ageing figure. Successive Union Home Ministry deadlines for a final accord passed without signature through the early 2020s.

The NSCN-IM must be distinguished from adjacent entities. It is not the NSCN-K, the Khaplang faction based largely across the Myanmar border, which abrogated its own 2001 ceasefire with India on 27 March 2015 and orchestrated the 4 June 2015 Manipur ambush that killed 18 soldiers, prompting an Indian cross-border operation. Both are remnants of the original NSCN, itself a successor to the NNC. The Naga peace process is also separate from the broader instruments of counter-insurgency such as the Armed Forces (Special Powers) Act, 1958, which remains partially in force across the region, and from the Sixth Schedule autonomous arrangements that govern other Northeastern communities. Greater Nagalim, the IM's territorial claim, is fiercely opposed by Manipur, Assam and Arunachal Pradesh, making it the principal obstacle to any final settlement.

Controversy persists on several fronts. Manipur's territorial integrity is a recurrent flashpoint: the 2001 extension of the NSCN-IM ceasefire "without territorial limits" triggered deadly riots in Imphal in which protesters stormed the state assembly. Allegations of extortion, parallel taxation and factional killings have dogged the group during the ceasefire years, and clashes between the IM and rival Naga factions continue intermittently. The 2021 Oting incident in Mon district, in which security forces killed civilians, reignited demands for AFSPA repeal and underscored how unsettled the security environment remains even after decades of dialogue. The confidentiality of the Framework Agreement itself has drawn criticism for excluding the Nagaland legislature and the public from a process that will reshape their political status.

For the working practitioner, the NSCN-IM is a case study in protracted ceasefire-based conflict transformation: an insurgency contained but not concluded, where a signed framework has not produced a final accord more than a quarter-century after the guns fell largely silent. Desk officers and analysts tracking India's Northeast must follow the interplay between the IM track and the NNPGs, the unresolved flag-and-constitution impasse, the cross-border dimension involving Myanmar, and the constitutional limits New Delhi has set on integration and shared sovereignty. The group exemplifies why ripeness, inclusive participation and territorial sensitivities determine whether negotiated peace endures or relapses.
