Nagaland and Mizoram: Separatist Demands, Statehood and Accords (ISC Class 12 History)

Updated 17 October 2026 · Fact-checked

In Nagaland the NNC under Phizo claimed independence in 1947, an armed struggle followed, Nagaland became a state on 1 December 1963 and a section of underground leaders signed the Shillong Accord on 11 November 1975, though hard-liners rejected it. In Mizoram the MNF under Laldenga rebelled in 1966; the Mizo Accord of 30 June 1986 ended the insurgency and Mizoram became a state in 1987.

Nagaland got statehood (1963) before its accord (1975) and hard-liners rejected it; Mizoram's accord (1986) came first, then statehood (1987).

Understand Nagaland and Mizoram: From Insurgency to Accord

What the syllabus asks. "Nagaland: The Nagas' separatist demands; birth of Nagaland state; course of the agitation; Shillong Accord, 1975." and "Mizoram: Mizoram Movement (1959-1986): course and resolution." Both are Centre-State topics from the North-East; treat each in four short parts.

A. Nagaland.
1. *Separatist demands.* The Nagas, a group of tribes with a distinct culture, felt they had never been part of India. The Naga National Council (NNC), led by A. Z. Phizo, declared Naga independence on 14 August 1947 and claimed in 1951 that a plebiscite had shown overwhelming support for it. The NNC boycotted the 1952 elections and, from the mid-1950s, began an armed struggle and set up an underground "Federal Government". The army was deployed, and the Armed Forces (Special Powers) Act was passed in 1958.
2. *Birth of Nagaland.* Moderate Nagas formed the Naga People's Convention (1957), which negotiated a 16-point agreement with the Centre (1960). The Naga Hills-Tuensang area became the state of Nagaland, inaugurated on 1 December 1963, with special constitutional protection for Naga customary law and land (Article 371A).
3. *Course after statehood.* A Peace Mission, which included Jayaprakash Narayan, B. P. Chaliha and Rev. Michael Scott, arranged a ceasefire in 1964, but talks failed. Violence resumed, and the ceasefire ended in 1972 when the NNC was banned.
4. *Shillong Accord (11 November 1975).* A section of the underground leaders agreed to accept the Constitution of India unconditionally, to surrender arms and to formulate other issues for a final settlement.
5. *Aftermath.* Hard-liners (Isak Chisi Swu, Thuingaleng Muivah and S. S. Khaplang) rejected the Accord as a sell-out and formed the National Socialist Council of Nagaland (NSCN) in 1980, so the conflict continued.

B. Mizoram.
1. *Origins.* The Mizo Hills were a district of Assam. In 1959 bamboo flowering caused a plague of rats that destroyed crops (the "mautam" famine), and relief from the Assam government was slow. The Mizo National Famine Front was formed and became the Mizo National Front (MNF) in 1961 under Laldenga. Assam's decision to make Assamese the official language added to resentment.
2. *Course.* The MNF demanded independence. On 28 February-1 March 1966 it launched an armed uprising, attacked government posts and declared independence. The government responded with force, including air strikes around Aizawl and the controversial regrouping of villages to cut off support to the rebels. Laldenga and the MNF fought from bases across the border in East Pakistan, and the insurgency continued for two decades. In 1972 the Mizo Hills became the union territory of Mizoram. On-and-off talks were held with Laldenga from the mid-1970s.
3. *Resolution.* The Mizo Accord (30 June 1986), signed between the Rajiv Gandhi government and the MNF: the MNF gave up violence and surrendered arms; Mizoram would become a full state with special protection for Mizo religious and social practices and customary law (Article 371G); Laldenga became Chief Minister of an interim government. Mizoram became a state in February 1987.
4. *Significance.* The Mizo Accord is regarded as one of India's most successful peace settlements: the MNF entered democratic politics and peace has largely held.

Comparison. Both began as demands for independence; in Mizoram a full settlement was reached, while in Nagaland the 1975 Accord was partial and the conflict continued.

Nagaland and Mizoram: From Insurgency to Accord in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

A partial agreement leaves a split

Suppose a group of club members divides over a dispute, and some sign a settlement while others reject it as a betrayal and form their own group.

What follows?

Try it first, then show the solutionSolution
  1. Those who signed return to normal club life.
  2. Those who refused continue to press their demands.
  3. The conflict continues in a smaller form.

Answer: A settlement that not all sides accept can leave the dispute alive, as the rejection of the Shillong Accord by hard-liners led to the NSCN.

Memory hook: All sides or no peace.

Relief that comes late

Imagine a district whose crops are destroyed by pests and whose request for help is met slowly by the state office.

How might this affect people's trust?

Try it first, then show the solutionSolution
  1. People feel neglected.
  2. A local group that helps them gains support.
  3. Resentment can turn political.

Answer: Slow relief in the 1959 famine fed Mizo anger, and the group that organised famine relief became the MNF.

Memory hook: Late help, lost trust.

Where students lose marks in Nagaland and Mizoram: From Insurgency to Accord

The slips examiners see most often, and what to write instead.

  • Mistake: Confusing the two accords

    Both have "accord" and similar years.

    Wrong working

    The Shillong Accord settled Mizoram.

    Right working

    Shillong Accord (1975): Nagaland. Mizo Accord (1986): Mizoram.

    Do this: Shillong = Naga; Mizo = Mizo.

    Usually costs: 2 marks.

  • Mistake: Saying Nagaland was settled in 1975

    Overlooking the NSCN.

    Wrong working

    The Naga problem ended with the Shillong Accord.

    Right working

    A section signed; hard-liners formed the NSCN in 1980.

    Do this: Add "partial".

    Usually costs: 1-2 marks.

  • Mistake: Dating Mizoram statehood to 1986

    Accord date confused with statehood.

    Wrong working

    Mizoram became a state on 30 June 1986.

    Right working

    Accord on 30 June 1986; statehood in February 1987.

    Do this: Accord first, state later.

    Usually costs: 1 mark.

  • Mistake: Ignoring the government's use of force

    Telling only the insurgents' story.

    Wrong working

    The MNF attacked and the government negotiated.

    Right working

    The government used force, including air strikes and village regrouping, alongside talks.

    Do this: Include both.

    Usually costs: 1-2 marks.

Exam tips

  • Learn the two accord dates: 11 November 1975 (Shillong) and 30 June 1986 (Mizo).
  • For comparison questions, use a short table of leader, demand, settlement, outcome.
  • Name Articles 371A and 371G only if asked about safeguards.

  1. Q1 · 2 marks · Very short answerBoard level

    Who led the NNC and the MNF? [2]

    Hint

    Phizo and Laldenga.

    Answer

    A. Z. Phizo led the Naga National Council and Laldenga led the Mizo National Front.

  2. Q2 · 3 marks · Short answerBoard level

    What was the "mautam" and why is it important in Mizo history? [3]

    Hint

    Bamboo flowering and rats.

    Answer

    The mautam was the 1959 famine caused by a plague of rats after bamboo flowering, which destroyed crops. Slow relief from the Assam government led to the formation of the Mizo National Famine Front, which became the MNF.

  3. Q3 · 4 marks · Short answerHarder board level

    Explain the protection given to Nagaland under Article 371A and to Mizoram under Article 371G. [4]

    Hint

    Customary law, religious and social practices.

    Answer

    Article 371A gave Nagaland special protection for Naga customary law and land. Article 371G gave Mizoram protection for Mizo religious and social practices and customary law. Both were intended to reassure tribal communities that statehood would not threaten their way of life.

  4. Q4 · 5 marks · Short answerHarder board level

    Compare the outcomes of the Shillong Accord (1975) and the Mizo Accord (1986). [5]

    Hint

    Partial versus full.

    Answer

    The Shillong Accord was signed by only a section of the Naga underground, and hard-liners formed the NSCN, so the conflict continued. The Mizo Accord was signed by the main insurgent group, the MNF, which gave up violence, entered democratic politics and formed an interim government; Mizoram became a state and peace has largely held.

  5. Q5 · 6 marks · Long answerHOTS / competency

    "Statehood within the Indian Union is the best way of settling insurgencies in the North-East." Evaluate using Nagaland and Mizoram. [6] (Evaluation)

    Hint

    Compare how far statehood and accords ended violence.

    Answer

    In Mizoram statehood with special protection followed an accord with the insurgents and has led to lasting peace. In Nagaland, statehood in 1963 did not end the conflict: the 1964 ceasefire collapsed, the Shillong Accord was partial and the NSCN continued the struggle. Statehood therefore helps when it comes with an agreement accepted by the main insurgent group and with safeguards for identity; without these it is insufficient. The evidence shows that the method works but is not a guarantee.
