The North-East of India, with its eight states (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura and Sikkim), is connected with the rest of India by a narrow land corridor of about 22 km, known as the Siliguri Corridor or "Chicken's Neck". The region has more than 200 ethnic groups and shares about 98 percent of its borders with Bhutan, China, Myanmar, Bangladesh and Nepal. Because of this geography and its complex social mix, it has seen decades of insurgency, demands for autonomy and ethnic conflict. For the UPSC Civil Services Examination, this topic is part of GS Paper 3 (Internal Security): Prelims asks about accords, groups and constitutional provisions, and Mains asks about the causes of insurgency and the policy response. This note explains the causes, the major conflicts state by state, the government's approach and the present situation in simple language, with tables.

Causes of Insurgency in the North-East

  • Geography and isolation: the region is cut off from the mainland, with hills, forests and porous borders that help insurgents to hide and move.
  • Ethnic diversity and identity concerns: numerous tribes with distinct cultures, languages and customs fear the loss of identity because of the migration of outsiders. Demands for separate homelands, autonomy or independence arise from this fear.
  • Migration and demographic change: large-scale inflow of people from Bangladesh and from other parts of India changed the population balance in some areas (Assam, Tripura), leading to the fear of land loss and political marginalisation.
  • Economic backwardness and neglect: poor infrastructure, few jobs and a sense of being ignored by the Centre.
  • Weak governance and corruption: insufficient delivery of services and the misuse of funds.
  • External support: in the past, some groups received shelter and arms from neighbouring countries, with camps in Myanmar, Bangladesh and Bhutan; cross-border drug and arms trafficking in the Golden Triangle region also funds insurgents.
  • Historical factors: the colonial policy of treating hill areas as "excluded areas" and the late integration of some areas.

State-wise Overview

StateMajor groups and issuesSettlement or response
NagalandThe Naga National Council led by A. Z. Phizo demanded independence from the 1950s; later groups: NSCN (IM) and NSCN (K); demand for "Greater Nagalim" covering Naga areas of Manipur, Assam and ArunachalStatehood in 1963; Shillong Accord (1975); ceasefire with NSCN (IM) since 1997; Framework Agreement (2015); talks continue; Article 371A protects Naga customs
AssamThe Assam Agitation (1979-85) against illegal migrants; the ULFA (formed in 1979) demanded a sovereign Assam; Bodo groups (NDFB, BLT) demanded a BodolandAssam Accord (1985); Bodo Accord (2003) creating the Bodoland Territorial Council; Bodo peace agreement (2020); Karbi Anglong Agreement (2021); peace agreement with the pro-talks faction of ULFA (2023)
ManipurMeitei groups (UNLF, PLA, PREPAK) demanded independence; Naga-Kuki ethnic clashes; the Meitei-Kuki conflict that erupted in May 2023AFSPA in force in some areas; peace efforts, deployment of forces and political dialogue
MizoramThe Mizo National Front under Laldenga began an uprising in 1966 after the famine of 1959Mizo Accord (1986); Mizoram became a state in 1987; seen as the most successful peace model
TripuraTribal groups like NLFT and ATTF fearing that Bengali migration reduced the tribals to a minorityTripura Tribal Areas Autonomous District Council; accords with the groups; insurgency largely ended
MeghalayaGroups such as HNLC and GNLA (smaller conflicts)Sixth Schedule councils; peace talks and surrender policies
Arunachal PradeshMostly spillover from Nagaland and Assam groups in some districts; Chinese claims on the borderSecurity deployment and development projects

The Constitution protects the tribal areas in several ways. The Sixth Schedule gives autonomous district and regional councils to tribal areas of Assam, Meghalaya, Tripura and Mizoram, with powers over land, forests, village administration and customs. Article 371A (Nagaland) says that Acts of Parliament on Naga religious or social practices, customary law and land ownership do not apply unless the Nagaland Assembly decides so. Article 371G gives similar protection to Mizoram. Article 371C provides for the hill areas of Manipur. The Inner Line Permit system, under the Bengal Eastern Frontier Regulation of 1873, restricts the entry of outsiders in some states such as Arunachal Pradesh, Nagaland, Mizoram and Manipur. The Armed Forces (Special Powers) Act, 1958 gives special powers to the forces in disturbed areas, and the Unlawful Activities (Prevention) Act is used against banned groups. The North Eastern Council (1971) and the Ministry of Development of North Eastern Region (DoNER) (2004) coordinate development.

Government's Approach

The government follows a mix of firm security measures and political and economic initiatives. Security: deployment of the Army, the Assam Rifles and the CAPFs, operations against militants, intelligence-based action, border fencing and cooperation with Bhutan, Myanmar and Bangladesh (for example, Bhutan's action in 2003 and the cooperation with Bangladesh against the camps). Dialogue: ceasefires and peace talks with groups willing to give up arms, leading to a number of accords. Rehabilitation: surrender and rehabilitation schemes with financial support and training for ex-militants. Development: the "Act East" policy, improved roads, railways, airports and waterways; the Kaladan Multimodal Project and the Trilateral Highway; the North East Special Infrastructure Development Scheme; the Bogibeel Bridge (2018) over the Brahmaputra; and the opening up of trade with Southeast Asia. Political empowerment: autonomous councils, statehood and the protection of local customs.

Recent Developments

In the last decade, violence in most of the region has fallen sharply, and many insurgent groups have signed peace agreements, with the number of incidents, deaths and the area under AFSPA reducing considerably. Several accords were signed in 2019-2024, for example with the NLFT (2019), the Bru-Reang agreement (2020), the Bodo accord (2020), the Karbi Anglong agreement (2021), the inter-state border agreements between Assam and Meghalaya (2022) and the peace agreement with a faction of ULFA (2023). However, Manipur faced serious ethnic violence from May 2023, which showed that unresolved ethnic fault lines and the issues of land, identity and reservation can reignite conflict. The Naga political talks have not yet reached a final settlement, and the status of some demands remains open. The ending of the Free Movement Regime on the Myanmar border and the plan to fence the border have also been controversial among border communities.

Challenges

The main challenges are the unresolved Naga issue and the Manipur conflict; the problem of the demographic change and migration, which links with the debates on the Citizenship (Amendment) Act and the NRC; the extortion and "parallel governments" run by some groups; inter-state border disputes; the drugs and arms trade through the Myanmar border; the instability in Myanmar after 2021, with refugees and the movement of rebels; slow development and unemployment; and the fragile trust between the people and the security forces, since the AFSPA has been criticised. Another issue is the multiplicity of small groups with changing demands.

Way Forward

The way forward includes a long-term political settlement with the Naga groups, a fair and inclusive resolution in Manipur through dialogue among communities, quick implementation of the peace accords including the political and economic promises, protecting the rights and land of tribal communities through the Sixth Schedule and local institutions, a review of AFSPA with proper safeguards, better border management with technology and cooperation with neighbours, investment in infrastructure, education and jobs, development of local industries and tourism, and the involvement of civil society and women in peace-building. Connectivity under the Act East Policy can turn the region from a periphery into a gateway to Southeast Asia.

The Role of Women, Youth and Civil Society in Peace

Peace in the North-East has often been supported by groups outside the armed forces and the government. Mothers' groups such as the Meira Paibis of Manipur have played a prominent role in the protests against violence and for the protection of communities. Church bodies and tribal councils helped to bring the Naga and Mizo groups to the negotiating table. Student organisations and youth clubs have organised sports, music and cultural events to build bridges between communities. Women's participation in the peace process, supported by the principle of the UN Security Council Resolution 1325 on women, peace and security, is considered essential for a lasting settlement. Sports success of the region, such as the achievements of Mary Kom in boxing and the rise of the region's footballers and musicians, has also created pride and a sense of belonging in the national mainstream. A good Mains answer will say that security and development are necessary, but trust and participation make peace durable.
