Fall of the USSR & end of the Cold War

From Reform to Disintegration

The collapse of the Union of Soviet Socialist Republics (USSR) between 1985 and 1991 was driven less by a single shock than by the convergence of structural decay and a reform programme that loosened the controls holding the system together. When Mikhail Gorbachev became General Secretary of the Communist Party of the Soviet Union (CPSU) in March 1985, he inherited stagnant growth (the 'era of stagnation' under Leonid Brezhnev, 1964–1982), a defence burden estimated at 15–20% of GDP, and the costly war in Afghanistan launched in December 1979.

Gorbachev advanced two interlocking policies. Perestroika ('restructuring') sought to decentralise economic management; the Law on State Enterprise (1987) and the Law on Cooperatives (1988) introduced limited market mechanisms. Glasnost ('openness') relaxed censorship and permitted criticism of the Party. The Chernobyl disaster of 26 April 1986 became a turning point, exposing the cost of official secrecy and accelerating glasnost. Political liberalisation followed: the Congress of People's Deputies, elected in March 1989 with contested seats, gave dissent a national platform, and Article 6 of the 1977 Soviet Constitution — guaranteeing the CPSU's monopoly on power — was repealed in March 1990.

The Outer Empire Falls First

Gorbachev's repudiation of the Brezhnev Doctrine — replaced by what spokesman Gennady Gerasimov dubbed the 'Sinatra Doctrine' (letting allies go 'their way') — removed the threat of Soviet intervention that had crushed Hungary (1956) and Czechoslovakia (1968). The result was the revolutions of 1989. Poland's Solidarity, legalised after Round Table talks, won the partially free elections of June 1989. Hungary opened its Austrian border in May 1989. The Berlin Wall fell on 9 November 1989; Czechoslovakia's Velvet Revolution unfolded in November–December 1989; Romania's Nicolae Ceaușescu was executed on 25 December 1989. German reunification followed under the Two Plus Four Treaty of 12 September 1990, and the Warsaw Pact dissolved on 1 July 1991.

The Inner Collapse

Glasnost emboldened nationalism within the USSR itself. The Baltic states led: Lithuania declared independence on 11 March 1990, and Soviet crackdowns in Vilnius (January 1991) discredited the centre. Boris Yeltsin, elected President of the Russian Soviet Federative Socialist Republic in June 1991, became a rival power base. The decisive blow was the failed coup of 19–21 August 1991, when hardline Communists detained Gorbachev at Foros; Yeltsin's defiance atop a tank outside the Russian parliament broke the coup and shattered the CPSU's authority. The Belovezha Accords of 8 December 1991, signed by Russia, Ukraine and Belarus, declared the USSR dissolved and created the Commonwealth of Independent States. Gorbachev resigned on 25 December 1991, and the Soviet flag was lowered over the Kremlin for the last time on 26 December 1991.

Ending the Cold War: Summitry and Arms Control

The Cold War's diplomatic terminus ran parallel to the Soviet collapse. The Reagan–Gorbachev summits — Geneva (1985), Reykjavík (1986), Washington (1987) and Moscow (1988) — produced the Intermediate-Range Nuclear Forces (INF) Treaty signed on 8 December 1987, the first accord to eliminate an entire class of nuclear weapons. The Malta Summit of 2–3 December 1989 between George H. W. Bush and Gorbachev is conventionally cited as the declaration that the Cold War was over. The Strategic Arms Reduction Treaty (START I) followed on 31 July 1991, and the Treaty on Conventional Armed Forces in Europe (CFE) was signed in November 1990.

Why This Matters for the Exam

This topic is high-yield across the shared world-history layer. For UPSC GS-1, the syllabus explicitly lists 'the redrawal of national boundaries' and post-WWII developments; the end of the Cold War and its consequences for the unipolar moment recur in Mains. For FSOT, the Cold War's conclusion underpins US foreign-policy questions and the post-1991 international order. For CSS (Pakistan) and BCS (Bangladesh), international relations and general-knowledge papers test the chronology and the causes debate.

Examiners reward a causation framework, not narrative. Organise causes into: (1) economic — central-planning inefficiency, the oil-price collapse of 1986 that gutted hard-currency revenue, and the arms-race burden; (2) political-ideological — glasnost delegitimising the Party, the repeal of Article 6, rising nationalism; (3) external — Reagan's pressure (the 1983 Strategic Defense Initiative), the Afghan quagmire (Soviet withdrawal completed February 1989), and Pope John Paul II's role in Poland; (4) leadership/contingency — Gorbachev's choices and the August 1991 coup's failure.

High-Yield Facts and the PYQ Angle

Memorise the spine: 1985 (Gorbachev), 1986 (Chernobyl, Reykjavík), 1987 (INF), 1989 (revolutions, Malta, Afghan withdrawal), 1990 (German reunification, Article 6 repealed), 1991 (coup, Belovezha, dissolution). Distinguish end of the Cold War (a geopolitical process, roughly 1989–1991) from collapse of the USSR (a constitutional event, December 1991) — conflating them is a common error penalised in evaluation.

PYQs cluster on two analytical prompts: 'Did the USSR collapse from internal contradictions or external pressure?' and 'Assess the consequences of the Cold War's end for the developing world / for India's non-aligned foreign policy.' The 1991 Indian balance-of-payments crisis and the LPG reforms of July 1991 are frequently linked to the loss of the Soviet trading partner — a connection examiners reward when candidates bridge world and national history. Francis Fukuyama's 'The End of History?' (1989) and Samuel Huntington's 'Clash of Civilizations' (1993) are the canonical interpretive references.
