GS Paper 1 practice questions for UPSC Mains 2026.

Introduction: Akbar (r. 1556–1605) consolidated Mughal rule less through battlefield expansion after 1576 than through institutional and ideological innovation.

Body — three dimensions: (1) Mansabdari system: zat and sawar ranks introduced 1577, mansabdars as a numbered nobility from Iranis, Turanis, Rajputs and Indian Muslims — broke factional dominance. (2) Land revenue — Todar Mal’s Dahsala bandobast, 1580, ten-year average price-yield assessment. (3) Religious policy: abolition of jizya (1564), Rajput marriage alliances, Ibadat Khana debates (1575), Din-i-Ilahi (1582), sulh-i-kul as ruling principle.

Conclusion: Athar Ali’s thesis — mansabdari plus sulh-i-kul gave the Mughal state its 17th-century resilience; the unravelling under Aurangzeb shows what their dilution cost.

Introduction: The Quit India Movement, launched at Bombay on 8 August 1942 with Gandhi’s ‘Do or Die’ call, became a leaderless uprising after the wholesale arrest of Congress leadership the next morning.

Body — three dimensions: (1) Causes of leaderlessness: Operation Zero Hour arrests; failure of Cripps Mission in March 1942 had radicalised even the moderates. (2) Form of the uprising: parallel governments at Ballia (Chittu Pandey), Tamluk (Tamralipta Jatiya Sarkar) in Midnapore, Satara (Prati Sarkar under Y.B. Chavan); communications sabotage, attacks on police stations — over 250 stations destroyed. (3) Significance: showed the depth of nationalist consciousness even without central leadership; convinced the British that the Raj could not be policed; led to the post-war Cabinet Mission of 1946.

Conclusion: Quit India confirmed Bipan Chandra’s reading — Indian nationalism had become a mass force capable of acting without prompting from the top.

Introduction: The States Reorganisation Act 1956 redrew India’s internal map along linguistic lines, after a decade of contested commissions.

Body — weigh evidence: (1) Initial caution — Dar Commission, 1948, opposed linguistic states for fear of fragmentation; JVP Committee (Jawaharlal, Vallabhbhai, Pattabhi Sitaramayya), 1949, accepted same. (2) Trigger — Potti Sriramulu’s fast-unto-death and Andhra Pradesh, 1953, the first linguistic state. (3) Reorganisation — Fazl Ali Commission, 1953–55; States Reorganisation Act, 1 November 1956, reorganised into 14 states and 6 UTs along language. (4) Trade-off — democratic legitimacy and administrative convenience won against feared Balkanisation; later challenges (Punjabi Suba 1966, Telangana 2014) showed linguistic principle had limits.

Conclusion: Selig Harrison’s 1960 warning of ‘dangerous decades’ proved overstated; linguistic states became a tool of, not a threat to, Indian federalism.

Introduction: The southwest monsoon, June to September, delivers about 75% of India’s annual rainfall against a Long Period Average of 87 cm.

Body — three dimensions: (1) Atmosphere-ocean: ENSO — El Niño warm phase suppresses monsoon (2015, 2023 deficit years), La Niña typically enhances it (2020–22 triple-dip surplus). (2) IOD: discovered by N.H. Saji in 1999; positive IOD with warm western Indian Ocean offsets El Niño impact (1997, 2019). (3) Orography and circulation: Tibetan Plateau heating drives the Tibetan High and the easterly jet over peninsular India; the Mascarene High and Somali Jet supply moisture. The Western Disturbances govern winter precipitation.

Conclusion: Forecasting now treats the monsoon as a coupled system; IMD’s dynamical Monsoon Mission model uses these teleconnections to issue Long Range Forecasts.

Introduction: The Union Cabinet approved caste enumeration in Census 2027 on 12 December 2025, the first full caste count since 1931, at an outlay of ₹11,718.24 crore.

Body — weigh evidence: (1) Case for evidence: Mandal Commission (1980) recommended 27% OBC reservation based on a 1931 figure of 52%; no fresh data since. Indra Sawhney (1992) drew the 50% ceiling. (2) Recent demand: Maratha, Patidar, Jat agitations, Bihar caste survey 2023, sub-classification verdict in State of Punjab v. Davinder Singh (2024). (3) Risks: classification chaos in Mandal-listed castes; risk of cementing caste in administration; SECC 2011 caste data never released. M.N. Srinivas’ warning that counting hardens identity.

Conclusion: Andre Beteille’s caution — measurement is not neutral; whether caste data delivers justice depends on whether it is used for graded outcomes or political arithmetic.

Introduction: Sufism reached India in the late 12th century with Muinuddin Chishti's settlement at Ajmer (c. 1192). Four major silsilas — Chishti, Suhrawardi, Naqshbandi, Qadiri — translated Islamic mysticism into Indian idiom.

Body — three dimensions: (1) Chishti pattern: poverty, distance from state, music (sama), open kitchen (langar). Khwaja Muinuddin (Ajmer), Bakhtiyar Kaki (Delhi), Baba Farid (Pakpattan), Nizamuddin Auliya (Delhi), Nasiruddin Chiragh-i-Dilli, Bandanawaz Gesudaraz (Gulbarga). (2) Suhrawardi pattern: closeness to political power, accumulation of wealth, urban orientation — Bahauddin Zakariya at Multan accepted iqta from Iltutmish. (3) Sociological consequence: khanqahs as inter-religious meeting grounds, Hindavi vocabulary (Amir Khusrau as Nizamuddin's disciple), composite shrines drawing Hindu pilgrims at Ajmer and Pakpattan; Sufi malfuzat as social record. K.A. Nizami's 'Some Aspects of Religion and Politics in India during the Thirteenth Century' anchors the analysis.

Conclusion: The Sufi silsilas built a parallel civic infrastructure that supplemented the Sultanate state and shaped Indo-Islamic culture.

Introduction: The Cabinet Mission, comprising Pethick-Lawrence, Stafford Cripps and A.V. Alexander, arrived in March 1946 to negotiate the transfer of power. Its plan of 16 May 1946 was the last constitutional design that preserved a single Indian Union.

Body — three dimensions: (1) Provisions: rejection of Pakistan; three-tier federation — Union centre with defence, foreign affairs, communications; Groups A (Hindu majority), B (Punjab, NWFP, Sind, Baluchistan), C (Bengal, Assam) deciding their subjects; Constituent Assembly elected by Provincial Assemblies; interim government on representative basis. (2) Acceptance and breakdown: Congress accepted Constituent Assembly clauses but rejected mandatory grouping; Muslim League accepted full plan then withdrew on 29 July 1946 after Nehru's Bombay press conference on 10 July suggesting grouping was not binding; League called Direct Action Day 16 August 1946 — Great Calcutta Killings followed. (3) Path to partition: Wavell's interim government September 1946; Mountbatten Plan 3 June 1947; Indian Independence Act 18 July 1947; Radcliffe Boundary Award.

Conclusion: Sumit Sarkar's reading is that the Cabinet Mission's grouping clause was conceptually unworkable; whether handled differently it could have produced a loose Indian federation is one of the most discussed counterfactuals in modern Indian history.

Introduction: The four Hindu Code Acts of 1955–56 — Hindu Marriage Act 1955, Hindu Succession Act 1956, Hindu Minority and Guardianship Act 1956, Hindu Adoption and Maintenance Act 1956 — were enacted by the first Lok Sabha after Ambedkar resigned in 1951 over their stalling.

Body — three dimensions: (1) Origins: Rau Committee (B.N. Rau, 1941) and Hindu Code Bill drafted by Ambedkar as Law Minister 1947–51; Constituent Assembly resistance from conservative members; President Rajendra Prasad's reservation; Ambedkar's resignation 27 September 1951. (2) Content: Hindu Marriage Act codified monogamy, allowed divorce; Hindu Succession Act gave daughters limited rights in coparcenary property (full coparcenary rights only after 2005 amendment); Adoption Act allowed adoption of a daughter; Guardianship Act made father natural guardian, mother only after him. (3) Limitations: applied only to Hindus, Sikhs, Jains, Buddhists, not to Muslims, Christians, Parsis — Uniform Civil Code under Article 44 still pending; many gender inequalities (Hindu Undivided Family taxation, Mitakshara coparcenary) corrected only by Hindu Succession (Amendment) Act 2005.

Conclusion: The Hindu Code laws were the largest single legislative intervention in personal law since 1947; their incomplete reach and gendered residues remain a constitutional unfinished agenda.

Introduction: The National Emergency of 25 June 1975 to 21 March 1977 — proclaimed by President Fakhruddin Ali Ahmed on Prime Minister Indira Gandhi's advice — followed the Allahabad High Court judgment of 12 June 1975 setting aside her election. The 44th Amendment of 1978 by the Janata government rolled back its excesses.

Body — three dimensions: (1) Emergency abuses: detentions under MISA, suspension of fundamental rights (ADM Jabalpur 1976 held Article 21 could be suspended); censorship of press; 42nd Amendment (November 1976) called the 'mini-Constitution' added 'socialist, secular' to the Preamble, curtailed judicial review, lengthened Lok Sabha term. (2) Janata response: 44th Amendment, June 1978 — Article 352 amended so emergency can be declared only for 'armed rebellion' not 'internal disturbance'; written cabinet recommendation required; Article 359 amended so Article 20 and Article 21 cannot be suspended; Right to Property removed from Part III (Article 31 to Article 300A). (3) Constitutional legacy: Minerva Mills (1980) reinforced basic structure; ADM Jabalpur expressly overruled in Puttaswamy 2017; demonstrated that constitutional norms can be restored after rupture.

Conclusion: The Emergency–44th Amendment sequence remains the clearest empirical case in Indian constitutional history of democratic self-correction.

Introduction: The Indian Ocean Dipole (IOD) was identified by N.H. Saji and colleagues in 1999 as a coupled ocean-atmosphere mode in the tropical Indian Ocean independent of ENSO.

Body — three dimensions: (1) Mechanism: defined by the Dipole Mode Index (DMI) — anomalous SST difference between the western (50°E–70°E, 10°S–10°N) and south-eastern (90°E–110°E, 10°S–0°N) tropical Indian Ocean. Positive IOD: warmer west, cooler east — enhances south-west monsoon rainfall in India. Negative IOD: reverse — suppresses monsoon. (2) Phases and case studies: 1997 positive IOD coincided with El Niño but still gave India near-normal rainfall; 2019 strong positive IOD compensated for weak El Niño, India had 110% of LPA; 2020 negative IOD pattern muted monsoon. (3) Forecasting: IMD's dynamic Monsoon Mission Coupled Forecasting System (MMCFS); NOAA Pacific buoy network; APEC Climate Center; needs better Indian Ocean RAMA buoy density; ENSO and IOD interaction in 'modoki' configurations remains under-modelled.

Conclusion: The IOD reduces the deterministic role of ENSO but increases the complexity of monsoon forecasting; better Indian Ocean observation infrastructure is the prerequisite for sub-seasonal predictions India's agriculture needs.

Introduction: The Ministry of Mines released the list of 30 Critical Minerals for India on 28 June 2023 — including lithium, cobalt, nickel, graphite, rare earths, titanium, zirconium and tin — based on the Veena Kumari Dermal Committee report.

Body — three dimensions: (1) Endowment and gaps: lithium reserves found at Salal-Haimana, Reasi (J&K) — 5.9 million tonnes inferred (GSI, February 2023); titanium-bearing beach sands of Kerala, Tamil Nadu, Odisha; graphite in Arunachal, Tamil Nadu, Odisha; rare earth in Indian monazite (KMML, IREL); cobalt and nickel essentially absent. (2) Import dependence: India imports 100% of lithium, cobalt, nickel for battery applications; 70%+ rare earth magnets from China; vulnerability for EV ecosystem, solar manufacturing, defence. (3) Policy framework: Mines and Minerals (Development and Regulation) Amendment Act 2023 — 24 critical minerals reserved for central government auction; KABIL (Khanij Bidesh India Ltd) for overseas acquisition; agreements with Argentina, Australia, Africa Mining Investment Vision; National Critical Mineral Mission 2024–25.

Conclusion: India's critical mineral strategy is now a four-track effort — domestic exploration, recycling, overseas acquisition and processing capacity; success in lithium-cobalt processing will determine whether India captures or just consumes the energy transition.

Introduction: About 90% of India's workforce is informal, generating roughly 50% of GDP. The Code on Social Security, 2020 was notified into force on 21 November 2025, defining gig and platform workers for the first time.

Body — three dimensions: (1) Scale — ILO India Employment Report 2024 puts informal employment at nearly 90%; e-Shram crossed 31.38 crore registrations as of November 2025; women 53.68% of registrants. (2) Gig growth — NITI Aayog (2022) projects gig workforce 77 lakh (2020-21) to 2.35 crore by 2029-30, 4.1% of total livelihood; women 28% share. (3) The gap — recognition without aggregator contributions actually flowing into the Social Security Fund; portability missing; PM-SYM and Atal Pension Yojana coverage thin.

Conclusion: Build a portable, contribution-based floor on the e-Shram rails — accident cover, maternity, pension — funded by a 1–2% aggregator levy as proposed by NITI Aayog.

Introduction: The 1993 Act and the PEMSR Act, 2013 ban manual scavenging and hazardous cleaning. Yet 294 sanitation workers died in 2020-24 (Rajya Sabha reply, February 2025).

Body — three dimensions: (1) Definitional gap — government claims ‘no manual scavenging’ while logging deaths as ‘hazardous cleaning’; NHRC has recommended widening the definition. (2) Caste pattern — of 58,098 manual scavengers identified, 97.25% with known caste are Scheduled Caste; about 92% of NAMASTE-profiled workers SC/ST/OBC; 77% Dalit (2025 study). (3) NAMASTE shift — National Action for Mechanised Sanitation Ecosystem launched July 2023, ₹349.73 crore for FY24-FY26; PPE kits, Ayushman cover, capital subsidy for vehicles; 90,942 workers profiled as of April 2026.

Conclusion: Mechanisation cannot end a caste-rooted practice alone — close the definitional loophole, enforce the PEMSR Act and end the Swachh Bharat single-pit irony (only ~13% twin-pit toilets).

Introduction: Scheduled Tribes are 8.6% of population (10.43 crore, Census 2011). 75 PVTGs identified across 18 states/UTs (originally Dhebar Commission 1960; renamed PVTG in 2006).

Body — three dimensions: (1) Constitutional architecture — Articles 342, 244; Fifth Schedule (10 states) and Sixth Schedule (4 NE states); PESA Act, 1996 extending Panchayati Raj to scheduled areas; FRA, 2006 recognising individual and community forest rights. (2) PVTG situation — Jarawas, Onges, Great Andamanese, Birhor, Bonda, Sahariya, Saharia, Cholanaikkans — pre-agricultural, low literacy, stagnant population. (3) Implementation gap — FRA recognises only ~50% of community forest rights claims; PM JANMAN ₹24,104 crore mission for PVTGs (November 2023) covers housing, road, water, mobile connectivity.

Conclusion: Replace welfare-as-substitution with rights-as-recognition under the FRA and PESA, and let Gram Sabhas drive PM JANMAN delivery for PVTGs.

Introduction: Define ‘treatment gap’. National Mental Health Survey (NMHS) 2015-16 — current adult prevalence 10.56%, lifetime 13.67%, treatment gap 70–86%, highest for common mental disorders.

Body — three dimensions: (1) Workforce — about 0.75 psychiatrists per lakh (WHO Atlas 2020) vs WHO benchmark of 3+; only ~9,000 psychiatrists for 1.4 billion. (2) Legal architecture — Mental Healthcare Act, 2017 — right to mental healthcare, decriminalised suicide attempt under Section 115, advance directive, Mental Health Review Boards; Section 309 IPC abolished. (3) Delivery — National Mental Health Programme since 1982, District Mental Health Programme in 767 districts; Tele MANAS (October 2022) — 24×7 helpline, 18.4 lakh calls handled by 2025.

Conclusion: Task-share with ASHAs, ANMs and lay counsellors under specialist supervision, fund the DMHP at scale and integrate with Ayushman Bharat Health and Wellness Centres.

Introduction: Global motor-vehicle production 93.5 million units in 2023 (OICA). Top three — China (30.16 m), USA (10.6 m), Japan (8.99 m). India ranked 3rd in passenger cars (5.5 m units, 2023).

Body — three dimensions: (1) Market access — Detroit (Michigan) historic capital served Midwest demand; Tokyo-Yokohama-Toyota City cluster serves Asia-Pacific. (2) Component ecosystem — Stuttgart-Munich-Wolfsburg (Daimler, BMW, VW) on Mittelstand supplier base; Shenzhen-Shanghai EV cluster (BYD, Tesla GigaShanghai). (3) Labour and policy — Chennai-Sriperumbudur-Hosur (Hyundai, Ford, Renault-Nissan, Royal Enfield) — ‘Detroit of India’; Manesar-Gurugram (Maruti); Sanand-Pune western corridor (Tata, Mahindra, Mercedes).

Conclusion: Automobile geography is now reshaped by EV battery sourcing — China's CATL, Korea's LG, India's PLI for ACC — pulling new plants toward lithium-mineral access and clean grid.

Introduction: The energy transition needs lithium (batteries), cobalt and nickel (cathodes), rare earths (magnets). Reserve concentration is extreme — Chile and Australia hold over half of lithium reserves; DRC produces 70% of world cobalt; China refines about 80% of rare earths.

Body — three dimensions: (1) Geography — Lithium Triangle (Chile-Argentina-Bolivia), Australia's Greenbushes (spodumene), DRC's Katanga copperbelt for cobalt, Indonesia's Sulawesi for nickel laterite, China's Bayan Obo for rare earths. (2) India's discoveries — 5.9 million tonnes lithium inferred resource in Reasi, J&K (GSI February 2023), KABIL JV in Argentina; Karnataka's Mandya lithium prospect. (3) Policy — Critical Minerals List 30 minerals (June 2023); MMDR Amendment 2023 allowing private auctions; National Critical Minerals Mission ₹16,300 crore (January 2025).

Conclusion: Diversify supply via Mineral Security Partnership (US-led, India joined June 2023), build refining capacity, recycle e-waste — concentrate of resource = concentration of power.
