What this dot point is asking
VCAA wants you to analyse the collapse of the Soviet Union and the end of the Cold War between 1985 and 1991, identifying Gorbachev's reforms, the cascade of Eastern European revolutions, and the dissolution of the USSR.
Structural causes
Economic stagnation. Soviet GDP growth fell from % (1960s) to under % (1980s). Centrally planned economy could not match market economies in innovation or consumer goods.
Defence burden. Up to % of GDP. Reagan's military buildup (from 1981) and Strategic Defense Initiative (March 1983) added pressure.
Afghanistan war (1979-1989). Soviet "Vietnam". Soviet dead, deep public unpopularity.
Political legitimacy. Brezhnev era stagnation; gerontocracy (Andropov 1982-1984, Chernenko 1984-1985 all died in office).
Gorbachev's reforms (1985-1991)
Mikhail Gorbachev became General Secretary (March 1985).
Glasnost (openness). Released political prisoners (Sakharov in 1986). Press freedom expanded. Chernobyl disaster (April 1986) tested and accelerated openness.
Perestroika (restructuring). Limited market reforms. Failed to deliver economic recovery; disrupted supply chains.
Foreign policy. INF Treaty (December 1987) eliminated intermediate-range nuclear missiles. Soviet withdrawal from Afghanistan (1989). UN address (December 1988) announced Soviet troop reductions in Europe.
Sinatra Doctrine (1989). Eastern European states could go "their way". Renunciation of the Brezhnev Doctrine.
Eastern European revolutions of 1989
Poland. Solidarity legalised; semi-free elections (June 1989) gave Solidarity overwhelming victory. Tadeusz Mazowiecki became first non-communist Prime Minister in the Eastern bloc (August 1989).
Hungary. Reformist communist government opened the border with Austria (May 1989), creating a hole in the Iron Curtain.
East Germany. Mass exodus through Hungary and Czechoslovakia. Protests in Leipzig. Fall of the Berlin Wall (9 November 1989). Reunification (3 October 1990).
Czechoslovakia. Velvet Revolution (November-December 1989). Vaclav Havel became President.
Bulgaria, Romania. Bulgarian reformist communists; Romania's violent overthrow of Ceausescu (December 1989).
Dissolution of the USSR (1990-1991)
Baltic independence. Lithuania (March 1990), Latvia and Estonia followed.
1991 referendum. Soviet citizens voted to preserve the union, but six republics (Baltic states, Georgia, Moldova, Armenia) boycotted.
August 1991 coup attempt. Hardline communists held Gorbachev hostage in Crimea. Boris Yeltsin (President of the Russian SFSR) defied the coup from atop a tank in Moscow. Coup collapsed in three days.
Dissolution. Ukraine voted for independence (December 1991). On 8 December 1991, Russia, Ukraine and Belarus declared the USSR dissolved. Gorbachev resigned on 25 December 1991.
Aftermath
Fifteen successor states. Russia as the legal continuator. Yeltsin's market reforms ("shock therapy") brought hyperinflation and oligarchic capitalism. Putin came to power in 1999.
NATO expansion eastward (Czech Republic, Hungary, Poland 1999; Baltic states 2004). Russian resentment of NATO expansion would shape 21st-century politics.
Historiography
John Lewis Gaddis (The Cold War, 2005). Emphasised Reagan's pressure plus Gorbachev's reformism.
Stephen Kotkin (Armageddon Averted, 2001). Emphasised Soviet internal weaknesses.
Vladislav Zubok (Collapse: The Fall of the Soviet Union, 2021). Recent archival synthesis.
In one sentence
The Soviet Union collapsed between 1985 and 1991 because Gorbachev's glasnost and perestroika reforms failed to revitalise a structurally weak economy while opening space for nationalist movements and Eastern European revolutions (Poland, Hungary, the fall of the Berlin Wall 9 November 1989, Velvet Revolution, Romania); the August 1991 hardline coup attempt collapsed in three days and the USSR formally dissolved on 25 December 1991, ending the Cold War.

A Year 11 response.
Thesis. The collapse of the Soviet Union was not inevitable but became increasingly likely once Gorbachev's reforms (1985-1989) opened space for nationalist movements in the Soviet republics and reformist politics in Eastern Europe while failing to deliver economic recovery; the August 1991 coup attempt was the proximate trigger of dissolution rather than its underlying cause.
Body 1: Structural problems. The Soviet economy had stagnated through the 1970s and 1980s; GDP growth fell from % (1960s) to less than % (1980s). Defence spending consumed perhaps % of GDP. Afghanistan war (1979-1989) was costly and unsuccessful.
Body 2: Gorbachev's reforms. Glasnost (openness) allowed criticism. Perestroika (restructuring) was partial economic reform that disrupted the planned economy without producing a working market. Sinatra Doctrine (1989) renounced the Brezhnev Doctrine; Eastern European communist regimes lost Soviet military backing.
Body 3: Cascade collapse (1989-1991). Poland's Solidarity election (June 1989); Hungary opened its border with Austria (May 1989); fall of the Berlin Wall (9 November 1989); Velvet Revolution in Czechoslovakia; Romanian Revolution. German reunification (October 1990). Lithuania, Latvia and Estonia declared independence. The August 1991 coup attempt against Gorbachev failed; Yeltsin emerged as leader of Russia. USSR dissolved on 25 December 1991.
Conclusion. Gorbachev's reforms intended to save the system but accelerated its collapse. The Cold War ended without direct US-Soviet war.
