Post-Independence

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Post-Independence India spans 15 August 1947 (Independence under the Indian Independence Act 1947) through the present, anchored by the Constitution adopted 26 November 1949 and enforced 26 January 1950. UPSC Prelims repeatedly tests these two distinct dates and the framing bodies behind them — the Constituent Assembly (President Rajendra Prasad; Drafting Committee Chair B.R. Ambedkar) drafted the text, while the British Parliament enacted the Independence Act.

The 1991 LPG reforms under PM P.V. Narasimha Rao and Finance Minister Manmohan Singh dismantled the Licence Raj, cut tariffs from ~350% to ~30%, and opened the mixed economy to foreign investment. Earlier, the Nehruvian model (Planning Commission 1950, Five Year Plans, Panchsheel 1954, NAM 1961) shaped non-alignment and state-led industrialisation until the 1967 and 1971 political-economic turning points.

Three high-yield Prelims traps: adoption vs commencement date of the Constitution; Pokhran-I (1974) vs Pokhran-II (1998); Operation Flood’s three phases (1970–80, 1981–85, 1985–96).
Article 370 abrogated 5 August 2019; Article 352 declared during the 1975–77 Emergency.
Planning Commission replaced by NITI Aayog on 1 January 2015.

Constitutional foundation and integration

The Constituent Assembly held 166 sittings over roughly three years, producing a text adopted 26 November 1949 and enforced 26 January 1950 — the latter chosen to commemorate the 1930 Purna Swaraj declaration. Simultaneously, Sardar Patel and V.P. Menon integrated 562+ princely states via Instruments of Accession; Hyderabad (police action 1948), Junagadh, and Kashmir (accession October 1947, leading to Article 370) were the most contested.

Nehruvian nation-building (1947–64)

Nehru set up the Planning Commission (1950), Atomic Energy Commission (1948), IITs, and ISRO’s predecessor. The First Plan (1951–56) used the Harrod–Domar growth model; the Second Plan (1956–61) adopted the Mahalanobis model prioritising heavy industry. Foreign policy rested on Panchsheel (1954) and the Non-Aligned Movement (Bandung 1955, Belgrade 1961). Linguistic states were reorganised under the States Reorganisation Act 1956, beginning with Andhra (1953).

Crises and turning points (1962–1989)

The 1962 Sino-Indian War ended Nehru’s non-alignment optimism. Indo-Pak wars of 1965 and 1971 culminated in Bangladesh’s liberation and the Shimla Agreement (1972). The 1975–77 Emergency suspended Fundamental Rights under Article 352; the 42nd Amendment (1976) later entrenched Parliament’s supremacy. Pokhran-I (1974) was India’s first peaceful nuclear test. The 1989 Mandal–Mandir phase reshaped coalition politics.

Era	Anchor policy	Outcome
1950–69	Mixed economy, Five Year Plans	State-led industrialisation
1975–77	Emergency (Art. 352)	Suspended Fundamental Rights
1991–99	LPG reforms	Tariffs cut, FDI ceilings raised
2014–19	NITI Aayog (2015), GST (2017)	Cooperative federalism

The 1991 LPG reforms

Triggered by a balance-of-payments crisis, the reforms abolished industrial licensing except in 18 sectors, dismantled public-sector monopoly in many areas, established SEBI (1992), and introduced rupee convertibility on the trade account.

Edge cases and adjacent links

The Green Revolution (HYV seeds, M.S. Swaminathan, 1960s–70s) solved Punjab/Haryana’s food deficit but widened regional inequality — a recurring GS1 Mains theme on continuity vs change from colonial agrarian structures. Operation Flood (White Revolution, Verghese Kurien) ran in three distinct phases: Phase I (1970–80) linked 18 milk sheds with Delhi; Phase II (1981–85) expanded to 136 milk sheds; Phase III (1985–96) consolidated India’s status as the world’s largest milk producer. Mains often expects you to contrast these phases.

Constitutional continuity is tested through amendments: 1st (1951) added the Ninth Schedule; 42nd (1976) is the “mini-Constitution” (added words Socialist, Secular, Integrity to the Preamble); 44th (1978) reversed much of 42nd; 73rd and 74th (1992) devolved power to Panchayats and Municipalities. Article 370’s abrogation (5 Aug 2019) reorganised Jammu & Kashmir into two Union Territories.

Common mistakes to avoid

Conflating adoption and commencement dates (26 Nov 1949 vs 26 Jan 1950).
Attributing the Independence Act to the Constituent Assembly — it was a British Parliamentary statute.
Citing the Planning Commission as the current apex policy body — NITI Aayog replaced it on 1 January 2015.
Calling 1991 reforms “privatisation only” — LPG stands for Liberalisation, Privatisation, and Globalisation.
Mislocating Pokhran tests: Pokhran-I (1974, Indira Gandhi, “Smiling Buddha”) vs Pokhran-II (1998, Vajpayee).

Worked Mains prompt

“Examine how the integration of princely states shaped India’s federal character.” (Hint: Instruments of Accession, States Reorganisation Act 1956, Article 370 as a unique autonomy arrangement later abrogated.)

Practice prompts

Assess the social costs of Partition and the institutional response to refugee rehabilitation (1947–51).
Critically evaluate whether the 1991 LPG reforms represented a rupture or an evolution of the Nehruvian economic model.
