What this dot point is asking
NESA expects you to explain how the Soviet Union, having permitted the collapse of its outer empire in 1989, dissolved in 1991 through a combination of nationalist mobilisation, economic crisis, the failure of perestroika, the rise of Yeltsin, the failed August coup, and the Belavezha Accords.
The answer
The economic collapse
By 1990 the Soviet economy was contracting. Official GDP fell 2.4 per cent in 1990 and 17 per cent in 1991. The state budget deficit reached 11 per cent of GDP. The Soviet government had effectively lost monetary control: republics issued their own coupons, hoarded goods, and refused to deliver tax to Moscow. Inflation by 1991 was running at over 100 per cent annually; basic goods (sugar, soap, bread) were rationed. Hard currency reserves fell to about $100 million by November 1991, insufficient for any imports.
The 500-Day Plan (Stanislav Shatalin, Grigory Yavlinsky, August 1990) proposed rapid marketisation. Gorbachev hesitated and combined the plan with conservative Premier Ryzhkov's alternative, producing an incoherent package. Yeltsin endorsed the Shatalin plan; the rivalry was set.
The nationalist mobilisation
The Baltic states had never accepted Soviet annexation as legitimate. The Molotov-Ribbentrop Pact's secret protocols (acknowledged by the Soviet Congress in December 1989) underpinned the moral case. Popular fronts emerged: Sajudis in Lithuania (June 1988), Rahvarinne in Estonia (October 1988), Tautas Fronte in Latvia (October 1988). The Baltic Way on 23 August 1989 was a 600-kilometre human chain from Tallinn through Riga to Vilnius commemorating the Pact.
Declarations of independence: Lithuania (11 March 1990), Estonia (20 August 1991), Latvia (21 August 1991). The Soviet attempt to suppress the Lithuanian independence movement (Vilnius television tower, 13 January 1991, 14 killed) and the Latvian movement (Riga, January 1991) failed. The Bush administration recognised Baltic independence on 2 September 1991.
Caucasus: Nagorno-Karabakh conflict between Armenia and Azerbaijan from 1988 (the first armed inter-republican conflict). The Tbilisi massacre (9 April 1989) killed 21 Georgian demonstrators and broke Georgian loyalty. Black January (20 to 21 January 1990) saw Soviet troops kill at least 137 in Baku.
Ukraine: Rukh (the People's Movement) founded September 1989. Sovereignty declaration 16 July 1990. The 1 December 1991 independence referendum produced a 90.3 per cent yes (with 84 per cent turnout), including majorities in the Russian-speaking east. The result killed the Union.
Russian sovereignty and Yeltsin
Boris Yeltsin had been ousted from the Politburo by Gorbachev in 1987 after publicly criticising the pace of reform. He returned through the Russian Congress of People's Deputies elections (March 1990). On 29 May 1990 he was elected Chairman of the Russian Supreme Soviet by 535 votes to 467. On 12 June 1990 the Russian Federation declared the supremacy of its laws over Soviet laws (the sovereignty declaration). Most other republics followed (the "parade of sovereignties").
The Russian presidency was created in 1991. Yeltsin won the first direct election on 12 June 1991 with 57 per cent of the vote against Ryzhkov and four others. Russia now had a directly elected president and the largest economy and military; the Soviet centre had only Gorbachev, who had been chosen by the Soviet Congress in 1990.
The Novo-Ogaryovo process
Gorbachev tried to save the Union through a new treaty negotiated at the Novo-Ogaryovo presidential dacha from April 1991. The proposed Union of Sovereign States would have replaced the centralised USSR with a confederal entity, retaining nine of the fifteen republics (the three Baltics, Georgia, Armenia, and Moldova were out).
The All-Union referendum (17 March 1991) on preserving the Union as a "renewed federation of equal sovereign republics" returned 76 per cent yes on a 80 per cent turnout, but only in the nine participating republics. The Baltics, Armenia, Georgia, and Moldova boycotted; Ukraine added a second question on its own sovereignty, which also passed.
The treaty was scheduled for signing on 20 August 1991. The conservatives moved first.
The August Coup, 19 to 21 August 1991
The State Committee on the State of Emergency (GKChP) declared on the morning of 19 August 1991 that Gorbachev was incapacitated and that Vice President Gennady Yanayev was assuming the presidency. The committee included KGB Chairman Vladimir Kryuchkov, Defence Minister Dmitry Yazov, Interior Minister Boris Pugo, Prime Minister Valentin Pavlov, and others. Gorbachev was held under house arrest at his Foros dacha in Crimea.
Yeltsin reached the Russian White House at the Krasnopresnenskaya embankment and at 12.40 pm climbed on to a T-72 tank from the Taman Division to issue Decree No. 59 declaring the coup illegal. About 60,000 people gathered to defend the White House. The Alpha and Vympel special forces refused orders to storm the building during the night of 20 to 21 August. Three protesters died in incidents on Sadovoye Koltso. The coup collapsed on 21 August. Pugo killed himself; Yazov, Kryuchkov, and others were arrested.
Gorbachev returned to Moscow on 22 August but had been politically discredited. Yeltsin signed Decree No. 79 suspending the CPSU in Russia on 23 August; Gorbachev resigned as General Secretary on 24 August.
The dissolution
The Ukrainian independence referendum on 1 December 1991 (90 per cent yes) ended the Union politically. Without Ukraine, no Union was viable.
The Belavezha Accords were signed on 8 December 1991 at the Belovezhskaya Pushcha nature reserve in Belarus by Yeltsin (Russia), Stanislau Shushkevich (Belarus), and Leonid Kravchuk (Ukraine). The accord declared the USSR dissolved and replaced it with the Commonwealth of Independent States (CIS).
The Alma-Ata Declaration (21 December 1991) added Kazakhstan and the other Central Asian and Caucasian republics to the CIS, except Georgia and the Baltics.
Gorbachev resigned as Soviet President in a televised speech on 25 December 1991. The Soviet flag was lowered from the Kremlin Senate at 7.32 pm and the Russian tricolour raised. President Bush's televised speech recognising the new states and declaring "the Cold War is over" followed at 9 pm Washington time.
The Supreme Soviet voted itself out of existence on 26 December 1991.

Historiography
Stephen Kotkin's Armageddon Averted (2001) argues the collapse was an uncoerced internal Soviet event. Serhii Plokhy's The Last Empire (2014) emphasises Ukraine's role. Vladislav Zubok's Collapse (2021) is the major recent treatment using Russian archives. Mark Galeotti's We Need to Talk About Putin (2019) follows the legacies. Mary Sarotte's Not One Inch (2021) covers the Western non-expansion assurances.
Common exam traps
Treating the August coup as the cause. The coup catalysed the dissolution but the dissolution was driven by Ukrainian independence and Yeltsin's Russian state.
Conflating Gorbachev's strategic intent. He wanted reform within the Soviet system. The 1991 outcome was unintended.
Misdating the formal end. 25 December 1991 (Gorbachev's resignation) is conventional; the USSR formally ceased to exist on 26 December 1991 when the Supreme Soviet voted itself out.
In one sentence
The Soviet Union collapsed in 1991 through the conjunction of economic crisis, Baltic and Caucasian nationalism, Ukrainian independence (referendum 1 December 1991), Yeltsin's Russian state under direct election (June 1991), the failed August coup (19 to 21 August 1991) that discredited the Soviet centre, and the Belavezha Accords (8 December 1991), ending with Gorbachev's resignation and the lowering of the Soviet flag on 25 December 1991.

Practice (NESA)15 marksWhy did the Soviet Union collapse in 1991?Show worked answer →
A 15-mark "why" needs causal hierarchy.
Structural causes. Economic stagnation; the failure of half-marketised perestroika; commodity-price dependence and the collapse of oil prices; the cost of empire (Afghanistan, Eastern Europe, Cuba); the chronic underperformance of the planned economy.
Glasnost's consequences. Cultural opening delegitimised the regime. Memorial documented Stalinist crimes; nationalist movements mobilised in the Baltics (Singing Revolution 1988 to 1991), Ukraine (Rukh, September 1989), Armenia and Azerbaijan (Nagorno-Karabakh from 1988), and Georgia (Tbilisi massacre, 9 April 1989).
The Russian opposition. Boris Yeltsin's election as Chairman of the Russian Supreme Soviet (29 May 1990), Russian sovereignty declaration (12 June 1990), and presidential election (12 June 1991, 57 per cent of the vote) created a Russian state inside the USSR with a directly elected leader, which Gorbachev was not.
The coup. Conservatives in the KGB, Defence, and Interior Ministries launched a coup on 19 August 1991 to prevent the New Union Treaty signing scheduled for 20 August. Gorbachev was detained at Foros. Yeltsin's defiance on a tank at the Russian White House and three days of crowd resistance broke the coup by 21 August. The CPSU was banned.
The dissolution. Ukrainian referendum on independence (1 December 1991, 90 per cent yes). Belavezha Accords (8 December 1991) dissolved the USSR. Gorbachev resigned on 25 December 1991. The Soviet flag was lowered from the Kremlin at 7.32 pm.
Judgement. Gorbachev's reforms unintentionally destroyed the system they were meant to save; nationalism and Yeltsin's Russian opposition pulled the union apart; the coup catalysed the dissolution by discrediting the centre.
