GS Paper 1 practice questions for UPSC Mains 2026.

Introduction: Place the Indus / Harappan civilisation in the Bronze Age (c. 2600–1900 BCE) and frame the dual claim — urban planning plus craft specialisation.

Body — three dimensions: (1) Hydraulic engineering: Great Bath at Mohenjodaro, Dholavira’s sixteen reservoirs, Lothal dockyard. (2) Town planning: grid streets, citadel–lower town division, covered drains, standardised baked bricks (1:2:4 ratio). (3) Craft and trade economy: shell from Nageshwar, carnelian beads from Chanhudaro, weights in 16-ratios, Meluhha seals at Mesopotamian sites.

Conclusion: The Harappan achievement was an integrated urban system; recent excavations at Rakhigarhi and Sinauli are extending, not overturning, this picture.

Introduction: Bhakti as a c. 7th-to-17th century devotional ferment, originating with the Alvars and Nayanars of Tamil country.

Body — three dimensions: (1) Nirguna stream: Kabir (Banaras weaver), Guru Nanak (Punjab), Dadu Dayal — rejection of idol worship, attack on caste, vernacular utterance. (2) Saguna stream: Tulsidas (Awadhi Ramcharitmanas), Surdas (Krishna bhakti, Braj), Mirabai (Rajasthan). (3) Regional and linguistic spread: Chaitanya in Bengal, Shankaradeva in Assam, the Varkari tradition of Maharashtra — Jnaneshwar, Namdev, Tukaram. Use of Awadhi, Braj, Marathi, Bengali, Punjabi against Sanskrit elitism.

Conclusion: Bhakti was India’s first mass vernacular cultural movement, simultaneously religious, social and linguistic.

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 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 Dandi March (12 March to 6 April 1930) launched the Civil Disobedience Movement by walking 240 miles from Sabarmati Ashram to the Dandi sea coast in Gujarat.

Body — three dimensions: (1) Symbolic: salt as universal commodity, breaking a tax monopoly that fell hardest on the poorest — inverting Lord Salisbury’s claim that salt was not a political issue. (2) Strategic: 78 chosen marchers, daily speaking halts, nation-wide replication on the West and East coasts — Sarojini Naidu at Dharasana, C. Rajagopalachari’s Vedaranyam march. (3) International: world press coverage by United Press’ Webb Miller, the Salt March as the moment Indian nationalism became a global news story; led to the Gandhi-Irwin Pact, 5 March 1931 and Gandhi’s Second Round Table Conference visit.

Conclusion: Dandi turned an obscure tax into the most legible image of colonial injustice and made the Congress a global political actor.

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 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: PLFS 2023-24 reports FLFPR at 41.7%, an 18-point rise in six years; the headline conceals a quality problem.

Body — weigh evidence: (1) Composition: most of the rise sits in unpaid family labour and self-employment in agriculture; salaried regular wage share for women fell to 15.9%. (2) Care burden: NSO Time Use Survey 2024 — women do 289 minutes a day of unpaid domestic work, men 88 minutes (3.3x gap). (3) Policy: Maternity Benefit Amendment 2017, Anganwadi crches under Mission Saksham Anganwadi, Code on Wages 2019, Lakhpati Didi scheme; missing pieces — universal childcare, paid eldercare, social security for gig and self-employed women.

Conclusion: Diane Elson’s ‘recognise, reduce, redistribute’ frame for care work is the missing third pillar; without it, FLFPR rises will keep being counted, not paid.

Introduction: India’s urban share, last measured at 31.16% in Census 2011, is projected by the World Bank’s 2025 report to reach about 951 million urban Indians by 2050.

Body — three dimensions: (1) Migration: 45.36 crore migrants in Census 2011, with rural-to-urban moves driving city growth. PRS data shows over 80% of urban informal workers are migrants. (2) Housing: National Buildings Organisation puts the urban housing shortage at 1.88 crore in 2012 with 95% in EWS and LIG; PMAY-Urban 2.0 (September 2024) sanctioned around 3.53 lakh houses by mid-2025. (3) Governance: 74th Constitutional Amendment 1992 devolved 18 functions to ULBs but state finance commissions remain weak; municipal own revenue is 1% of GDP against the global 7%.

Conclusion: The Isher Judge Ahluwalia HPEC 2011 report’s estimate of ₹39 lakh crore in urban investment over 20 years is still the benchmark; without fiscal devolution to ULBs the dual city will harden.

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: Place the Rigvedic period c. 1500–1000 BCE in the Sapta Sindhu region. Pastoralism dominates the literary surface (gau-dhana, cattle-raid hymns) but archaeology and stray hymns reveal a working agrarian base.

Body — three dimensions: (1) Irrigation and field practice: avata (well), kulya (canal), khanitra (digging tool) in the Rigveda; ploughing references in book IV; barley (yava) as principal crop. (2) Kshetra and ritual: the kshetra-pati hymn (RV IV.57) personifies the field; Atharvaveda's kshetra-patni elevates the 'mistress of the field' as ritual presence; agricultural rites bind the household economy. (3) Continuity into Later Vedic: shift to Doab, iron axes (krishna ayas), expansion into Painted Grey Ware villages — agriculture moves from supplementary to principal. R.S. Sharma's 'Material Culture and Social Formations' anchors this transition.

Conclusion: The pastoral idiom of the Rigveda masks an emerging agrarian order whose deepening through the Later Vedic period laid the base for the second urbanisation.

Introduction: The Gupta age (c. 319–550 CE) under Chandragupta I, Samudragupta, Chandragupta II and Skandagupta is conventionally framed as a classical golden age, a label that deserves disaggregation.

Body — three dimensions: (1) Cultural synthesis: Sanskrit literature peaks with Kalidasa's Abhijnanashakuntalam and Meghaduta, Vishakhadatta's Mudrarakshasa; Aryabhatiya (499 CE) defines astronomy and mathematics; Nalanda emerges as a mahavihara; classical sculpture at Sarnath, Deogarh, Udayagiri caves; decimal system formalised. (2) Political reach: Samudragupta's Allahabad pillar lists conquests but most southern kings remain tributary, not annexed; Hun invasions weaken Skandagupta; empire collapses by mid-6th century. (3) Limits and critique: D.N. Jha and R.S. Sharma point to early feudalism — land grants to Brahmanas and temples, decline of urban-monetary economy, hardening of varna and patriarchy as recorded in Smritis.

Conclusion: The Gupta age is golden in art, science and Sanskritic culture; politically it is a north-Indian classical revival whose social undercurrents preview medieval Indian feudalism.

Introduction: The Sangam age, c. 300 BCE to 300 CE, in the Tamil country south of Tirupati is documented in 2,300 odd poems compiled in the Ettutogai and Pattupattu.

Body — three dimensions: (1) Three crowned dynasties (Muvendar): Chera with capital Vanji and emblem palmyra, controlling Malabar pepper trade; Chola with Uraiyur and tiger emblem on Kaveri delta; Pandya with Madurai and fish emblem on the Vaigai. (2) Society and patronage: tinai ecological zones (kurinji, mullai, marudam, neithal, palai); bards (pulavar) sustained by puram poetry praising the king's munificence (kodai). (3) Trade: Muziris and Arikamedu connect with Roman empire — finds of Roman amphorae, Pliny on the pepper trade, Periplus of the Erythraean Sea.

Conclusion: The Sangam polity is a Tamil classical synthesis of clan kingship, ecological economy and Indian Ocean trade.

Introduction: Lord Curzon's partition of Bengal on 16 October 1905 carved a Muslim-majority eastern province; the Congress response, the Swadeshi movement, was the first mass nationalist mobilisation.

Body — three dimensions: (1) Four-fold method: boycott of British goods; swadeshi production (Bengal Chemicals founded by P.C. Ray, 1901; Bengal National College 1906); national education through National Council of Education; passive resistance and atmasakti. (2) Leadership and spread: Surendranath Banerjee, Aurobindo Ghose, B.G. Tilak, Bipin Chandra Pal, Lala Lajpat Rai — the Lal-Bal-Pal extremist axis. Reached Maharashtra, Punjab, Madras. (3) Limits and legacies: Surat split of 1907; alienation of Muslim elite that fed the All-India Muslim League's formation at Dhaka, 30 December 1906; revolutionary terrorism stream — Anushilan Samiti, Jugantar; partition annulled 12 December 1911 with capital shift to Delhi. Sumit Sarkar's 'The Swadeshi Movement in Bengal 1903–1908' is the definitive treatment.

Conclusion: Swadeshi shifted Indian nationalism from petitions to participation and inaugurated boycott, vernacular politics, women's mobilisation and constructive work — every later mass movement borrowed from this template.

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: Between 1793 and 1833 the East India Company experimented with three revenue regimes that together covered most of British India and shaped agrarian society into the 20th century.

Body — three dimensions: (1) Permanent Settlement (1793, Bengal, Bihar, Orissa, parts of Madras): Cornwallis fixed land revenue forever with zamindars as proprietors; created absentee landlordism, sub-infeudation, indebtedness; the Sunset Law dispossessed older zamindars. (2) Ryotwari (1820, Madras and Bombay): Thomas Munro and Captain Read settled directly with the cultivating ryot, revenue revised every 30 years, no intermediary — but revenue often set at 45–55% of gross produce, leading to chronic indebtedness and the Deccan Riots of 1875. (3) Mahalwari (1822, North-Western Provinces and Punjab): Holt Mackenzie and R.M. Bird settled with the village (mahal) treated as a corporate body, revenue collected through lambardars; revision every 20–30 years. (4) Common effect: cash revenue regardless of harvest, commercialisation of agriculture (cotton, indigo, opium), rise of moneylender, decline of village artisans — the Bengal famine of 1770 and Madras famine of 1876–78 expose the system's brittleness.

Conclusion: Bipan Chandra reads the three settlements as a single colonial project of revenue maximisation with regional variations; their structures echo into post-1947 land reform debates.

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: Between 1965 and 1990 the Indian state turned a food-deficit, milk-importing economy into a wheat-rice surplus producer and the world's largest milk producer through two state-led technological revolutions.

Body — three dimensions: (1) Green Revolution: launched after the 1965–66 drought and PL-480 dependence; Norman Borlaug's Mexican wheat varieties (Lerma Rojo, Sonora 64) and IRRI's IR-8 rice introduced by M.S. Swaminathan; package programme of HYV seeds, chemical fertilisers, assured irrigation, MSP and FCI procurement after 1965; output of foodgrains rose from 74 million tonnes in 1966-67 to 211 million tonnes by 2001-02. (2) White Revolution: Operation Flood launched 13 January 1970 under Verghese Kurien; Anand pattern co-operative federated as Gujarat Co-operative Milk Marketing Federation (Amul); India became the world's largest milk producer in 1998. (3) Continuity and consequences: both used cooperative-state hybrid institutions and price support; Green Revolution concentrated in Punjab, Haryana, western UP — by-passed eastern India, dryland regions; led to groundwater depletion (CGWB data — 78% blocks in Punjab over-exploited), soil salinity, agrarian distress; White Revolution diffused widely but caused buffalo monoculture and bovine population pressure.

Conclusion: Both revolutions show that scale was achieved by state-cooperative scaffolding; sustaining them now requires correcting regional and ecological imbalances.

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.
