Internal security: insurgencies, terrorism & federal responses

The four theatres of insurgency

Post-independence India has fought sustained armed challenges to its territorial and constitutional order across four broad theatres, each with distinct causes and trajectories.

The Northeast. The earliest insurgency erupted in the Naga Hills. Angami Zapu Phizo's Naga National Council declared independence on 14 August 1947 and held a plebiscite in 1951. Armed revolt from 1956 prompted the Armed Forces (Special Powers) Act, 1958 (AFSPA). The Shillong Accord (1975) split the movement; the NSCN factions (Isak-Muivah and Khaplang) emerged in 1980 and 1988. Mizoram's insurgency under Laldenga's Mizo National Front began with the 1966 uprising after the 1959 mautam famine; it ended cleanly with the Mizo Accord of 30 June 1986, statehood (1987), and Laldenga becoming Chief Minister—India's most successful counter-insurgency settlement. Assam's anti-foreigner agitation produced the Assam Accord (15 August 1985) and the secessionist ULFA (founded 1979).

Punjab. Sikh militancy crystallised around the Anandpur Sahib Resolution (1973) and Jarnail Singh Bhindranwale. Operation Blue Star (1–8 June 1984) at the Golden Temple precipitated the assassination of Indira Gandhi on 31 October 1984 and the anti-Sikh pogrom. The Rajiv–Longowal Accord (24 July 1985) and police operations under K.P.S. Gill restored order by the early 1990s.

Jammu and Kashmir. Cross-border militancy escalated after the disputed 1987 state election, with the JKLF kidnapping of Rubaiya Sayeed (December 1989) and the exodus of Kashmiri Pandits (January 1990). The Kargil conflict (1999) and attacks on the J&K Assembly (2001) and Parliament (13 December 2001) followed.

Left-Wing Extremism (Naxalism). Born at Naxalbari, West Bengal, in May 1967 under Charu Majumdar and Kanu Sanyal, it formed the CPI(ML) in 1969. The merger of the People's War Group and the Maoist Communist Centre created the CPI (Maoist) on 21 September 2004, which Prime Minister Manmohan Singh called India's 'greatest internal security threat'. The 'Red Corridor' peaked after the Dantewada ambush (6 April 2010) that killed 76 CRPF personnel.

Terrorism beyond insurgency

Urban mass-casualty terrorism marks a distinct strand: the 1993 Bombay serial blasts (12 March), the 2001 Parliament attack, the 2006 Mumbai train bombings, and the 26/11 Mumbai attacks (26–29 November 2008) by Lashkar-e-Taiba, which directly produced the National Investigation Agency Act, 2008 and the Multi Agency Centre's revival.

The constitutional and legal architecture of response

Internal security sits at the heart of Indian federalism's asymmetry. Under the Seventh Schedule, 'public order' (Entry 1) and 'police' (Entry 2) are State List subjects, while the Union controls the armed forces, CRPF, BSF and atomic energy. This division forces a cooperative—and often contested—response architecture.

Emergency provisions. Article 355 imposes a duty on the Union to protect every State against 'external aggression and internal disturbance'. Article 356 permits President's Rule on failure of constitutional machinery; it was invoked in Punjab in 1983–85 and 1987–92. Article 352's 'internal disturbance' ground (used in 1975) was replaced by 'armed rebellion' through the Forty-fourth Amendment, 1978—a direct lesson of the Emergency.

Deployment statutes. AFSPA, 1958 grants the armed forces powers to fire and arrest in 'disturbed areas' notified under Section 3. The Supreme Court upheld its constitutionality in Naga People's Movement of Human Rights v. Union of India (1998) but bound it with the Do's and Don'ts. Extra Judicial Execution Victim Families Association v. Union of India (2016) held that there is no absolute immunity and ordered investigation of alleged fake encounters. The Justice Jeevan Reddy Committee (2005) recommended AFSPA's repeal.

Anti-terror law. The trajectory runs TADA (1985–1995, lapsed for misuse), POTA (2002–2004, repealed), and the Unlawful Activities (Prevention) Act, 1967—strengthened by the 2004, 2008 and 2019 amendments, the last allowing designation of individuals as terrorists. Kartar Singh v. State of Punjab (1994) upheld TADA while reading in safeguards.

Institutional response. The Group of Ministers report (2001, post-Kargil) and the Second Administrative Reforms Commission's fifth report restructured intelligence. Post-26/11 came the NIA (2008), NATGRID, and the National Security Guard's regional hubs.

Why this matters for the exam

For UPSC Mains GS-1, this theme straddles the syllabus item 'post-independence consolidation and reorganization' and bleeds into GS-3 ('linkages of development with extremism', 'role of external state and non-state actors', 'security challenges'). Examiners reward candidates who connect cause (development deficit, ethnic identity, cross-border sponsorship) to response (legal instrument, accord, institution) and who evaluate the federal tension between Union authority and State policing.

PYQ angle: GS-1 2017 asked about the Northeast's distinct identity issues; GS-3 has repeatedly probed LWE root causes and the AFSPA debate. High-yield retention list: AFSPA Section 3 and 4, Articles 355/356, the dated accords (Mizo 1986, Assam 1985, Shillong 1975, Punjab 1985), the NPMHR (1998) and EEVFAM (2016) cases, the UAPA 2019 amendment, and the NIA's creation in 2008. Always cite the accord-by-name, not 'a peace deal'.
