The Fall of Communism

Mikhail Gorbachev's reforms of glasnost and perestroika, designed to make the Soviet system more flexible, produced the unintended consequence of accelerating the dissolution of Soviet hegemony rather than reforming the bloc. The 1989 cascade of revolutions across Eastern Europe — from the Polish Round Table elections of June 1989 through the fall of the Berlin Wall on 9 November 1989 to the violent overthrow of Nicolae Ceausescu in Romania in December 1989 — ended Communist Party rule across the bloc. The August 1991 Moscow coup attempt, the Belavezha Accords of December 1991, and Gorbachev's resignation on 25 December 1991 produced the formal dissolution of the Soviet Union and the end of the Cold War.

Learning Objectives

By the end of this lesson, students will be able to:

  • Account for the causes and effects of the end of the Cold War (Skill 3.D; LO G).
  • Account for KC-4.2.V.C: how Mikhail Gorbachev's reforms of perestroika and glasnost, designed to make the Soviet system more flexible, failed to prevent the collapse of the Soviet Union and the end of its hegemonic control over Eastern and Central European satellites.
  • Account for KC-4.1.IV.E: how the collapse of the Soviet Union in 1991 ended the Cold War and produced the establishment of capitalist economies throughout Eastern Europe, the reunification of Germany, the Czech-Slovak partition, the Yugoslav dissolution, and the eastern enlargement of the European Union.
  • Examine how reform-era Soviet documents (Gorbachev's UN speech of December 1988), Eastern European transition documents (Havel's 1990 New Year address), and dissolution documents (Belavezha Accords of December 1991) reinforce, adjust, or undermine each other as historical evidence (Skill 3.D in direct practice).
  • Account for the principal phases of the 1989 cascade of revolutions across Poland, Hungary, East Germany, Czechoslovakia, Bulgaria, and Romania.

Key Concepts

Topic 9.7 covers the end of the Cold War between approximately 1985 and 1991. KC-4.2.V.C captures the internal Soviet dimension: Gorbachev's reforms of perestroika and glasnost, designed to make the Soviet system more flexible, failed to prevent the collapse. KC-4.1.IV.E captures the broader European reorganization: the Soviet collapse ended the Cold War and produced the establishment of capitalist economies across Eastern Europe, German reunification, the Czech-Slovak partition, Yugoslav dissolution, and eastern EU enlargement. The lesson is structured in four parts: Gorbachev's reforms (1985-1988); the 1989 cascade of revolutions; the dissolution of the Soviet Union (1991); and the post-1989 reorganization of Europe.

Gorbachev's reforms (1985-1988). Mikhail Gorbachev's selection as General Secretary of the Communist Party of the Soviet Union on 11 March 1985 (succeeding Konstantin Chernenko, who had succeeded Yuri Andropov in February 1984; both Andropov and Chernenko had ruled briefly in declining health) introduced the principal late-Soviet reform leadership. Gorbachev was 54 at his selection, the youngest General Secretary since Stalin's elevation in 1922; his prior career had been in the Stavropol Krai Komsomol and Communist Party apparatus and as Secretary for Agriculture under Andropov. The Soviet economy at his accession faced substantial difficulties: declining oil prices (the principal Soviet hard-currency export source) had reduced foreign-exchange earnings; agricultural productivity remained well below Western European levels; consumer-goods shortages were chronic; the Soviet defense burden (approximately 15-25 percent of Soviet GDP at the early-1980s peak, compared to approximately 6 percent for the United States) was substantial; the Afghanistan war was producing rising Soviet casualties without strategic progress.

Gorbachev's reform program developed in three phases. The first phase (1985-1986) addressed visible administrative dysfunction: the May 1985 anti-alcohol campaign substantially reduced alcohol production and consumption at substantial cost to state revenue; the June 1985 selection of Eduard Shevardnadze (a Gorbachev ally) as Foreign Minister produced the substantial reorientation of Soviet foreign policy; the December 1986 release of physicist and human-rights advocate Andrei Sakharov from internal exile in Gorky (Sakharov had been confined since January 1980 over his opposition to the Afghan war) signaled the developing political opening. The April 1986 Chernobyl nuclear-power-plant disaster (the worst civil nuclear accident to that date; approximately 31 immediate deaths from the explosion and acute radiation; substantially higher long-term cancer attributions; substantial environmental contamination across Belarus, Ukraine, and parts of Russia) substantially shaped Gorbachev's subsequent commitment to glasnost: the initial Soviet attempt to suppress information about the disaster failed in the face of Western detection of the radiation plume and substantially eroded the regime's information-control capacity.

The second phase (1986-1988) introduced the principal reform programs. Glasnost ("openness") relaxed press censorship and political restrictions: previously banned books were published (Boris Pasternak's Doctor Zhivago in 1988; Anatoly Rybakov's Children of the Arbat in 1987; Vasily Grossman's Life and Fate in 1988); the Soviet press began critical reporting on previously-unmentionable topics (the Stalinist purges; the Afghan war; the Soviet economic difficulties; environmental catastrophes); independent civic and political organizations began to operate. Perestroika ("restructuring") attempted to introduce market mechanisms into the Soviet command economy: the 1987 Law on State Enterprise gave Soviet enterprises substantial autonomy from central planning; the 1988 Law on Cooperatives legalized small private businesses; the 1990 Law on Property and the 1991 reforms attempted but failed to produce a substantial private-property-based economy. Demokratizatsiya ("democratization") loosened the Communist Party monopoly on political life: the 19th Conference of the Communist Party of the Soviet Union in June-July 1988 authorized contested elections to a new Congress of People's Deputies; the March 1989 elections produced the principal partial-democratic Soviet election with substantial reform-Communist and non-Communist successes.

The third phase (1988-1989) renounced the Brezhnev Doctrine. Gorbachev's address to the United Nations General Assembly on 7 December 1988 was the principal public renunciation: Gorbachev announced unilateral Soviet conventional-arms reductions (500,000 troops, 10,000 tanks, 8,500 artillery pieces, 800 combat aircraft over the next two years); committed the Soviet Union to "freedom of choice" in international affairs (the implicit renunciation of the right to intervene in Warsaw Pact states); and articulated the broader concept of "common European home" that anticipated the post-Cold-War European order. The substantively decisive Eastern European consequence was that the 1989 reform movements could proceed without facing the threat of Soviet military intervention that had structured Eastern bloc politics since the Brezhnev Doctrine of November 1968.

"Following a long period of economic stagnation, Mikhail Gorbachev's internal reforms of perestroika and glasnost, designed to make the Soviet system more flexible, failed to stave off the collapse of the Soviet Union and the end of its hegemonic control over Eastern and Central European satellites."AP Euro CED, KC-4.2.V.C (paraphrased)

The 1989 cascade of revolutions. The Eastern European 1989 revolutions proceeded through a roughly six-month cascade in which the success of the early transitions encouraged the subsequent ones. The Polish transition was the principal early case. The Polish Communist regime under Wojciech Jaruzelski had been substantially weakened by the 1980-1981 Solidarity crisis (Topic 9.4) and the cumulative economic difficulties of the 1980s; the Polish Round Table negotiations of February-April 1989 between the Communist regime and the legalized Solidarity movement produced the partially free elections of 4 June 1989 (Solidarity won 99 of 100 seats in the partially elected Senate and all 161 of the contested Sejm seats). The Tadeusz Mazowiecki government of 24 August 1989 became the first non-Communist-led government in the Eastern bloc since 1948. The Hungarian Communist regime under Karoly Grosz (succeeding Janos Kadar in May 1988) similarly negotiated a transition through the Hungarian Round Table of June-September 1989 that produced multiparty elections in March-April 1990 and the non-Communist Jozsef Antall government of May 1990.

The Hungarian decision to open the Hungarian-Austrian border on 2 May 1989 produced the principal early-summer crisis: substantial East German emigration through Hungary to Austria and West Germany. Approximately 13,000 East Germans had crossed the Hungarian-Austrian border by early September 1989; the Pan-European Picnic of 19 August 1989 (a brief opening of the border at Sopron, Hungary, organized by Hungarian opposition activists) produced the flight of approximately 600 East Germans to Austria; the Hungarian government's formal opening of the border to East German citizens on 11 September 1989 produced approximately 30,000 additional East German emigrations through October 1989. The East German regime under Erich Honecker faced compounding pressure: the Leipzig Monday demonstrations beginning 4 September 1989 (initially approximately 1,200 protesters; reached approximately 70,000 by 9 October 1989; reached approximately 320,000 by 23 October 1989); the dismissal of Honecker on 18 October 1989 in favor of Egon Krenz; and the Politburo's botched press-conference announcement of 9 November 1989 in which Politburo member Gunter Schabowski mistakenly announced that the new travel regulations took effect "immediately, without delay." East Berliners began crossing to West Berlin within hours; the Berlin Wall was opened across all checkpoints by midnight; the principal physical symbol of the Cold War division of Europe had ended. German reunification followed under Chancellor Helmut Kohl's Ten-Point Programme of 28 November 1989 and the Two-Plus-Four Agreement of 12 September 1990; formal reunification took effect on 3 October 1990.

The Czechoslovak Velvet Revolution of 17 November to 29 December 1989 was the most rapid of the 1989 transitions. Student demonstrations on the fiftieth anniversary of the Nazi closure of Czech universities in 1939, met by violent police suppression on Narodni Trida ("National Avenue") in Prague on 17 November 1989, produced the rapid mobilization of the Civic Forum (Obcanske Forum) under playwright Vaclav Havel and the Slovak counterpart Public Against Violence (Verejnost proti nasiliu). The Communist regime under Milos Jakes resigned on 24 November 1989; the resulting negotiations produced the resignation of Communist President Gustav Husak on 10 December 1989 and the parliamentary election of Vaclav Havel as President on 29 December 1989. The Bulgarian transition followed a Communist Party-led pattern (Todor Zhivkov was deposed by a Politburo putsch on 10 November 1989; the resulting reform-Communist government negotiated a transition with the developing opposition; multiparty elections in June 1990 produced a temporarily Communist-led coalition that was subsequently replaced).

The Romanian transition was the violent exception. Nicolae Ceausescu's Communist regime had pursued an increasingly autocratic and personalistic course through the 1980s (the systematic destruction of historic Bucharest neighborhoods to build the gigantic Casa Poporului; the harsh anti-natalist-policy reversal that produced the orphan-institution catastrophe; the systematic Securitate surveillance). Demonstrations in Timisoara from 16 December 1989 (originally protesting the planned forced relocation of Hungarian-Reformed pastor Laszlo Tokes) escalated into a national uprising; Ceausescu's botched 21 December 1989 Bucharest balcony speech (in which he was visibly disconcerted by the crowd's hostile response) demonstrated the regime's collapsing authority; Ceausescu and his wife Elena fled by helicopter on 22 December 1989, were captured the same day, and were tried and executed on 25 December 1989 after a brief military tribunal. The post-Ceausescu National Salvation Front under Ion Iliescu took power; the December 1989 violence killed approximately 1,100 people, the only substantial death toll of the Eastern European 1989 revolutions.

The dissolution of the Soviet Union (1991). The 1989 Eastern European revolutions and the collapse of Soviet hegemonic authority over the Warsaw Pact substantially weakened Gorbachev's domestic political position. The principal late-Soviet political development was the rise of Boris Yeltsin, the former Moscow Communist Party chief whom Gorbachev had dismissed in November 1987 and who subsequently rebuilt his political position through the late 1980s. Yeltsin was elected to the Soviet Congress of People's Deputies in March 1989; resigned from the Communist Party at the 28th Congress in July 1990; was elected Chairman of the Russian Soviet Federative Socialist Republic (RSFSR) Supreme Soviet on 29 May 1990; and was directly elected President of the RSFSR on 12 June 1991 in the first popular Russian presidential election. Yeltsin's parallel democratic-Russian-nationalist political position substantially competed with Gorbachev's reform-Communist Soviet position.

The August 1991 Moscow coup attempt was the decisive crisis. A group of Communist hard-liners (the State Committee on the State of Emergency, including Vice President Gennady Yanayev, Defense Minister Dmitri Yazov, KGB Chairman Vladimir Kryuchkov, Interior Minister Boris Pugo, and Prime Minister Valentin Pavlov) detained Gorbachev at his Crimean dacha at Foros on 18 August 1991 and announced the assumption of authority on 19 August 1991. The coup attempt collapsed within three days: Yeltsin's resistance from the Russian Federation parliament building (the "White House") in Moscow, his iconic appearance atop a tank to read the resistance proclamation, and the principal Soviet military units' refusal to execute the coup orders produced the coup's collapse on 21 August 1991. Gorbachev returned to Moscow but with substantially reduced authority; the Communist Party of the Soviet Union was suspended on 24 August 1991 and formally dissolved on 6 November 1991; the Baltic states (Estonia, Latvia, Lithuania) declared independence (or in the Lithuanian case, completed the process begun in March 1990) and were internationally recognized in early September 1991.

The Belavezha Accords of 8 December 1991 produced the formal Soviet dissolution. Yeltsin (Russia), Leonid Kravchuk (Ukraine), and Stanislaus Shushkevich (Belarus) met at the Belovezhskaya Pushcha forest in Belarus and signed the agreement declaring that the Soviet Union "as a subject of international law and a geopolitical reality, ceases its existence" and establishing the Commonwealth of Independent States as the loose-association successor framework. The Alma-Ata Protocol of 21 December 1991 extended the Commonwealth of Independent States to most former Soviet republics (with the exceptions of Georgia, which acceded in 1993, and the three Baltic states, which declined to participate). Gorbachev resigned as President of the Soviet Union on 25 December 1991 (the Soviet flag was lowered from the Kremlin at 7:32 p.m. Moscow time and the Russian tricolor raised); the Soviet Union formally ceased to exist on 26 December 1991 with the Soviet of Republics' acknowledgment of the dissolution. The Cold War had ended.

The post-1989 reorganization of Europe (KC-4.1.IV.E). The collapse of the Soviet Union ended the Cold War and produced substantial reorganization of European political and economic life. The transition to capitalist economies across Eastern Europe followed varying patterns: Polish "shock therapy" under Finance Minister Leszek Balcerowicz from January 1990 (rapid price liberalization, currency stabilization, and privatization) produced an immediate sharp economic contraction followed by sustained growth; Hungarian and Czech transitions under more gradualist programs produced comparable longer-term outcomes; the Russian transition under Yegor Gaidar (1991-1992) and Anatoly Chubais (the principal architect of the 1992-1996 voucher privatization) produced substantial economic disruption, the collapse of GDP by approximately 40 percent through 1996, and the rise of the Russian "oligarch" class.

German reunification took effect on 3 October 1990 (the day commemorated as German Unity Day) following the Two-Plus-Four Agreement of 12 September 1990 (East Germany, West Germany, the United States, the Soviet Union, the United Kingdom, and France) that ended the formal four-power occupation rights and recognized the unified Germany's full sovereignty. The Czech-Slovak Velvet Divorce of 1 January 1993 separated the Czech Republic and Slovakia by negotiated agreement following the June 1992 elections that produced incompatible Czech and Slovak governing coalitions. The Yugoslav dissolution after 1991 produced the principal violent transition (Topic 9.5 covered). The eastern enlargement of the European Union proceeded in waves: ten states acceded on 1 May 2004 (Poland, Hungary, Czech Republic, Slovakia, Slovenia, Estonia, Latvia, Lithuania, plus Cyprus and Malta); Bulgaria and Romania acceded on 1 January 2007; Croatia acceded on 1 July 2013. NATO parallel enlargement extended to most former Warsaw Pact territory by 2024 (Poland, Czech Republic, and Hungary acceded in March 1999; the Baltic states, Bulgaria, Romania, Slovakia, and Slovenia in March 2004; Albania and Croatia in April 2009; Montenegro in June 2017; North Macedonia in March 2020; Finland in April 2023; Sweden in March 2024). Topic 9.10 will examine the European Union dimension in detail.

The Skill 3.D argument. Topic 9.7's suggested skill is 3.D (Source Argument: account for the way claims or evidence reinforce, adjust, or undermine the argument of a source). The skill applies particularly to the multi-perspective documentary record of the fall of communism. Gorbachev's reformist documents (the December 1988 UN speech; Perestroika 1987) advanced the argument that the Soviet system could be reformed within Communist Party leadership; the Eastern European transition documents (Havel's 1990 New Year address; the Solidarity 1989 election manifesto) advanced the argument that the Communist Party-led model was beyond reform and required wholesale replacement; the dissolution documents (Belavezha Accords; Gorbachev's resignation address of 25 December 1991) document the failure of the reform program and the resulting transition. Each set of documents advanced a substantive interpretation of the developing situation; the eventual outcome (system collapse rather than system reform) substantially undermined Gorbachev's reform claims and substantially confirmed the Eastern European transition documents.

Primary Source Excerpts

Three sources framing the fall of communism: the late-Soviet reform articulation, the Eastern European transition voice, and the dissolution agreement.

UN Address Wilson Center Cold War International History Project 1988

Mikhail Gorbachev, Address to the United Nations General Assembly, 7 December 1988

"World development is impossible without efforts toward a new world order... Today the further world progress is only possible through a search for universal human consensus as we move forward to a new world order... Freedom of choice is a universal principle. There should be no exceptions... It is now quite clear that the building up of military power makes no country omnipotent... It is obvious, for instance, that force and the threat of force can no longer be, and should not be, instruments of foreign policy... I should like to inform you that today the Soviet Union has made a decision on reducing its armed forces. In the next two years, their numerical strength will be reduced by 500,000 men, and the volume of conventional arms will also be cut considerably."

Mikhail Gorbachev (1931-2022), General Secretary of the Communist Party of the Soviet Union from 11 March 1985 and President of the Soviet Union from 15 March 1990 to 25 December 1991. Gorbachev's address to the 43rd Session of the United Nations General Assembly on 7 December 1988 was substantively the principal late-Cold-War Soviet renunciation of the Brezhnev Doctrine: the "freedom of choice" formulation explicitly committed the Soviet Union to non-intervention in the political-system choices of other states (including Warsaw Pact members); the unilateral conventional-arms reductions provided substantive evidence of the changed Soviet strategic posture; the broader concept of "common European home" anticipated the post-Cold-War European order. The speech was substantially welcomed in Western capitals (the New York Times described it as "an extraordinary speech that may well prove a watershed in twentieth-century history"); subsequent Eastern European reform leaders interpreted the speech as authorizing the 1989 transitions without fear of Soviet military intervention. Gorbachev was awarded the Nobel Peace Prize in 1990 for the broader reform program. For Topic 9.7 the source documents the principal Soviet reformist articulation that KC-4.2.V.C identifies as the proximate cause of the subsequent dissolution. Skill 3.D applies directly: the speech's claim that the Soviet system could be reformed within Communist Party leadership was substantially undermined by the subsequent 1989-1991 outcomes.

Presidential Address Vaclav Havel Library Foundation 1990

Vaclav Havel, New Year's Address to the Nation, Prague, 1 January 1990

"My dear fellow citizens, for forty years you heard from my predecessors on this day different variations on the same theme: how our country was flourishing, how many million tons of steel we produced, how happy we all were, how we trusted our government, and what bright perspectives were unfolding in front of us. I assume you did not propose me for this office so that I, too, would lie to you. Our country is not flourishing. The enormous creative and spiritual potential of our nations is not being used sensibly. Entire branches of industry are producing goods that are of no interest to anyone, while we are lacking the things we need... The worst thing is that we live in a contaminated moral environment. We fell morally ill because we became used to saying something different from what we thought. We learned not to believe in anything, to ignore one another, to care only about ourselves."

Vaclav Havel (1936-2011), Czech playwright, dissident, and politician. Havel had been a principal figure of Czechoslovak dissidence since the 1968 Soviet invasion: signatory of Charter 77 in January 1977; repeatedly imprisoned across the 1970s and 1980s (the longest term was 1979-1983 over the Committee for the Defense of the Unjustly Persecuted); author of The Power of the Powerless (1978) and the principal essayist of late-Communist Czechoslovak dissidence. The principal leader of the Civic Forum during the November-December 1989 Velvet Revolution; elected President of Czechoslovakia by the Federal Assembly on 29 December 1989. Havel delivered the New Year's Address on 1 January 1990 from Prague Castle, two weeks after his election, in deliberate counterpoint to the official New Year addresses of the Communist period. The address was broadcast live on Czechoslovak television and radio and substantially shaped the subsequent democratic-political reorientation of Czechoslovakia. Havel served as President of Czechoslovakia (1989-1992) and subsequently as President of the Czech Republic (1993-2003) after the Velvet Divorce. For Topic 9.7 the source documents the Eastern European transition voice that the 1989 revolutions produced. Skill 3.D applies directly: Havel's claim that the Communist system was morally corrupt and beyond reform substantially adjusts the parallel Gorbachev claim that the system could be reformed within Communist Party leadership.

Vaclav Havel, "New Year's Address to the Nation, Prague, 1 January 1990," in Vaclav Havel: The Art of the Impossible: Politics as Morality in Practice, translated by Paul Wilson (New York: Knopf, 1997), pp. 1-9. View at the Vaclav Havel Library Foundation →
International Agreement United Nations Treaty Series 1991

The Belavezha Accords (Agreement Establishing the Commonwealth of Independent States), Belovezhskaya Pushcha, 8 December 1991

"We, the Republic of Belarus, the Russian Federation (RSFSR), and Ukraine, as the founding states of the USSR which signed the Union Treaty of 1922, hereinafter referred to as the High Contracting Parties, do hereby establish that the USSR, as a subject of international law and a geopolitical reality, ceases its existence... The High Contracting Parties guarantee that all the rights and freedoms granted by Article 12 of the Treaty on the Establishment of the USSR shall be observed... The High Contracting Parties hereby form a Commonwealth of Independent States."

The Belavezha Accords were signed on 8 December 1991 at the Viskuli government dacha in the Belovezhskaya Pushcha forest in Belarus by Boris Yeltsin (President of the Russian Soviet Federative Socialist Republic), Leonid Kravchuk (President of the Ukrainian SSR), and Stanislaus Shushkevich (Chairman of the Supreme Soviet of the Belarusian SSR). The principal historical-legal claim of the agreement was that the three founding republics of the 1922 Treaty Establishing the Soviet Union (Russia, Ukraine, and Belarus, plus the Transcaucasian SFSR which had subsequently dissolved) had the legal authority to dissolve the Union; the Soviet Union itself, including its central institutions and Gorbachev's presidency, was not consulted in the negotiation. The Alma-Ata Protocol of 21 December 1991 extended the Commonwealth of Independent States to most former Soviet republics; Gorbachev's resignation on 25 December 1991 and the Soviet of Republics' acknowledgment on 26 December 1991 produced the formal dissolution. The Belavezha Accords have been substantially contested in subsequent Russian political discourse: Vladimir Putin in his April 2005 address to the Federal Assembly described the dissolution of the Soviet Union as "the greatest geopolitical catastrophe of the twentieth century"; Yeltsin himself subsequently expressed mixed assessments of the agreement. For Topic 9.7 the source documents the formal dissolution that KC-4.1.IV.E identifies. Skill 3.D applies directly: the agreement's claim that the dissolution of the Soviet Union followed legitimately from the 1922 founding treaty was contested by Gorbachev (who had no opportunity to participate in the negotiation) and by subsequent Russian political voices.

Discussion Questions

  1. (Causation, Skill 3.D) Examine how Gorbachev's December 1988 UN address and Havel's January 1990 New Year address advance substantially different arguments about the Communist system. How does each source's specific claims reinforce, adjust, or undermine the other's?
  2. (Causation) Account for KC-4.2.V.C: how did Gorbachev's reforms of perestroika and glasnost fail to prevent the collapse of the Soviet Union and the end of its hegemonic control over Eastern and Central European satellites? Cite specific reform programs and the unintended consequences they produced.
  3. (Causation) Account for the cascade of 1989 Eastern European revolutions. Why did the reform pattern proceed substantially peacefully across Poland, Hungary, East Germany, Czechoslovakia, and Bulgaria, and why was the Romanian transition the violent exception?
  4. (Causation, Skill 3.D) Examine the Belavezha Accords of December 1991 as a historical document. What does the agreement's claim about the legitimate authority of the three founding republics presuppose? How was the claim contested by Gorbachev and by subsequent Russian political voices?
  5. (Causation) Account for KC-4.1.IV.E: how did the collapse of the Soviet Union end the Cold War and produce the establishment of capitalist economies across Eastern Europe, German reunification, the Czech-Slovak partition, and the eastern enlargement of the European Union?

Classroom Activities

25 min

1989 Cascade Workshop

On the board, draw a horizontal timeline from January 1989 to December 1989. In small groups, students place the principal events: Polish Round Table February-April; Hungarian-Austrian border opening 2 May; Polish elections 4 June; Pan-European Picnic 19 August; East German exodus through Hungary September-October; Leipzig Monday demonstrations 4 September onward; opening of Berlin Wall 9 November; Velvet Revolution 17 November to 29 December; Bulgarian transition 10 November; Romanian Revolution 16-25 December. Identify the principal trigger that produced each next event. Skill 3.D in direct practice on the cumulative documentary record.

20 min

Three Voices Source Reading

Distribute the Gorbachev UN speech (December 1988), Havel New Year address (January 1990), and Belavezha Accords (December 1991) excerpts as a chronological sequence. In pairs, students complete a four-row matrix for each source: principal claim; intended audience; historical situation; how the source reinforces, adjusts, or undermines the others. Skill 3.D in direct practice.

15 min

Reform-and-Outcome Comparison

In pairs, students compare Gorbachev's reform program (glasnost, perestroika, demokratizatsiya, renunciation of the Brezhnev Doctrine) with the actual outcome (cascade of revolutions; Soviet dissolution; capitalist transition). What did Gorbachev intend, and what did the reforms actually produce? The activity makes the unintended-consequences pattern that KC-4.2.V.C identifies concrete.

20 min

Map of Post-1989 Europe

Distribute two maps of Europe: 1989 frontiers (immediately before the cascade of revolutions) and 2010 frontiers (after the principal post-1989 reorganizations). In small groups, students identify the principal territorial changes: German reunification (October 1990); Soviet dissolution (December 1991); Czech-Slovak partition (January 1993); Yugoslav dissolution (1991-2008); Baltic state independence (August 1991); eastern EU enlargement (2004, 2007, 2013). The activity makes the post-1989 European reorganization that KC-4.1.IV.E identifies visible at a glance.

Vocabulary

Soviet politician; General Secretary of the Communist Party of the Soviet Union from 11 March 1985 and President of the Soviet Union from 15 March 1990 to 25 December 1991. Principal architect of glasnost, perestroika, and demokratizatsiya. Awarded the Nobel Peace Prize in 1990. Resigned on 25 December 1991, ending the Soviet Union. Subsequent post-Soviet political career was substantially marginal (his 1996 presidential candidacy received approximately 0.5 percent of the vote).
"Openness" — Gorbachev's reform program of relaxed press censorship and political restrictions, beginning in 1986 and substantially expanded after the April 1986 Chernobyl disaster. Principal manifestations: publication of previously banned books (Pasternak's Doctor Zhivago 1988; Rybakov's Children of the Arbat 1987; Grossman's Life and Fate 1988); critical Soviet press reporting on previously-unmentionable topics; legalization of independent civic organizations; the December 1986 release of Andrei Sakharov from internal exile.
"Restructuring" — Gorbachev's economic-reform program attempting to introduce market mechanisms into the Soviet command economy. Principal measures: the 1987 Law on State Enterprise (substantial enterprise autonomy from central planning); the 1988 Law on Cooperatives (legalization of small private businesses); the 1990 Law on Property; subsequent attempts at substantial economic reform that the August 1991 coup attempt and the Soviet dissolution interrupted. Substantively failed to produce the intended reformed Soviet economic system.
"Democratization" — Gorbachev's political-reform program loosening the Communist Party monopoly on political life. Principal measures: the 19th Party Conference of June-July 1988 authorizing contested elections; the March 1989 elections to the new Congress of People's Deputies; the February 1990 Central Committee plenum that ended Article 6 of the Soviet Constitution (the constitutional Communist Party monopoly); the March 1990 establishment of the Presidency of the Soviet Union.
Catastrophic accident at the Chernobyl Nuclear Power Plant in northern Ukrainian SSR on 26 April 1986. Reactor 4 explosion during a safety test produced the principal civil nuclear accident to that date; approximately 31 immediate deaths from the explosion and acute radiation; substantially higher long-term cancer attributions; substantial environmental contamination across Belarus, Ukraine, and parts of Russia. The Soviet government's initial attempt to suppress information about the disaster failed and substantially eroded the regime's information-control capacity, contributing to Gorbachev's subsequent commitment to glasnost.
Soviet physicist and human-rights advocate; principal designer of the Soviet thermonuclear weapons program in the 1950s; subsequent dissident from the late 1960s onward. Awarded the 1975 Nobel Peace Prize. Confined to internal exile in Gorky from January 1980 over his opposition to the Afghan war; released in December 1986 by Gorbachev personally telephoning him to communicate the release. Elected to the Soviet Congress of People's Deputies in March 1989; principal advocate of the abolition of Article 6 of the Soviet Constitution (the Communist Party monopoly). Died of a heart attack on 14 December 1989.
Gorbachev's address to the United Nations General Assembly on 7 December 1988 was the principal public renunciation of the 1968 Brezhnev Doctrine. Gorbachev announced unilateral Soviet conventional-arms reductions (500,000 troops over two years); committed the Soviet Union to "freedom of choice" in international affairs; and articulated the broader concept of "common European home." The renunciation substantively authorized the 1989 Eastern European reform movements to proceed without facing the threat of Soviet military intervention.
Negotiations from 6 February to 5 April 1989 between the Polish Communist regime under Wojciech Jaruzelski and the legalized Solidarity movement under Lech Walesa. Produced the agreement on partially free elections (35 percent of Sejm seats and all 100 Senate seats opened to free competition; the remaining 65 percent of Sejm seats reserved for Communist and allied candidates) on 4 June 1989. Solidarity won 99 of 100 Senate seats and all 161 of the contested Sejm seats. The Tadeusz Mazowiecki government of 24 August 1989 became the first non-Communist-led government in the Eastern bloc since 1948.
Opening of the Berlin Wall on the night of 9-10 November 1989 after Politburo member Gunter Schabowski's 9 November 1989 press-conference announcement that the new East German travel regulations took effect "immediately, without delay." East Berliners began crossing to West Berlin within hours; the Wall was opened across all checkpoints by midnight; physical demolition followed through 1990. The principal symbolic event of the 1989 cascade. German reunification followed under Chancellor Helmut Kohl's Ten-Point Programme of 28 November 1989 and took effect on 3 October 1990.
Czechoslovak transition from 17 November to 29 December 1989. Began with student demonstrations on Narodni Trida in Prague on 17 November 1989 (the fiftieth anniversary of the Nazi closure of Czech universities); produced the rapid mobilization of the Civic Forum under Vaclav Havel and the Slovak Public Against Violence; the Communist regime under Milos Jakes resigned on 24 November 1989; Communist President Gustav Husak resigned on 10 December 1989; Vaclav Havel was elected President by the Federal Assembly on 29 December 1989. Named "velvet" for the substantially nonviolent character of the transition.
Czech playwright and politician; principal Czechoslovak dissident of the 1970s and 1980s. Signatory of Charter 77 (January 1977); repeatedly imprisoned across the 1970s and 1980s; author of The Power of the Powerless (1978). Principal leader of the Civic Forum during the November-December 1989 Velvet Revolution; elected President of Czechoslovakia by the Federal Assembly on 29 December 1989. Served as President of Czechoslovakia (1989-1992) and President of the Czech Republic (1993-2003) after the Velvet Divorce.
Romanian Communist politician; General Secretary of the Romanian Communist Party from 1965 and President of Romania from 1974 to his overthrow on 22 December 1989. Pursued an increasingly autocratic and personalistic course through the 1980s. Captured with his wife Elena on 22 December 1989; tried and executed by firing squad after a brief military tribunal on 25 December 1989. The principal violent transition of the 1989 Eastern European revolutions; approximately 1,100 people died in the December 1989 Romanian violence.
Russian politician; first President of the Russian Federation (10 July 1991 to 31 December 1999). Former Moscow Communist Party chief; dismissed by Gorbachev in November 1987; rebuilt his political position through the late 1980s; resigned from the Communist Party at the 28th Congress in July 1990; directly elected President of the RSFSR on 12 June 1991. Principal opponent of the August 1991 Moscow coup; signed the Belavezha Accords of December 1991. Resigned the presidency on 31 December 1999 and was succeeded by Vladimir Putin.
Coup attempt by Communist hard-liners (the State Committee on the State of Emergency: Vice President Yanayev, Defense Minister Yazov, KGB Chairman Kryuchkov, Interior Minister Pugo, Prime Minister Pavlov) from 19 to 21 August 1991. Detained Gorbachev at his Crimean dacha at Foros and announced the assumption of authority. Collapsed within three days through Yeltsin's resistance from the Russian parliament building (the "White House") and the principal Soviet military units' refusal to execute coup orders. Substantially accelerated the Soviet dissolution.
Agreement signed on 8 December 1991 at the Viskuli government dacha in the Belovezhskaya Pushcha forest in Belarus by Yeltsin (Russia), Kravchuk (Ukraine), and Shushkevich (Belarus). Declared that the Soviet Union "as a subject of international law and a geopolitical reality, ceases its existence" and established the Commonwealth of Independent States. The Alma-Ata Protocol of 21 December 1991 extended the CIS to most former Soviet republics. Gorbachev's resignation on 25 December 1991 and the Soviet of Republics' acknowledgment on 26 December 1991 produced the formal dissolution.
Reunification of East Germany (the German Democratic Republic) and West Germany (the Federal Republic of Germany) on 3 October 1990 (the day commemorated as German Unity Day). Followed Chancellor Helmut Kohl's Ten-Point Programme of 28 November 1989; the East German March 1990 elections that produced an Alliance for Germany government supporting reunification; the July 1990 monetary union; and the Two-Plus-Four Agreement of 12 September 1990 (East Germany, West Germany, the United States, the Soviet Union, the United Kingdom, and France) that ended the formal four-power occupation rights and recognized the unified Germany's full sovereignty.

AP Practice Questions

Multiple Choice Sample ~ 2 min
1Question: Which of the following best accounts for the relationship between Gorbachev's reforms and the dissolution of the Soviet Union?
  • (A) Gorbachev's reforms were entirely successful in producing the reformed Soviet system that he intended.
  • (B) Gorbachev's reforms of perestroika and glasnost, designed to make the Soviet system more flexible, failed to prevent the collapse of the Soviet Union and the end of its hegemonic control over Eastern and Central European satellites (KC-4.2.V.C); the renunciation of the Brezhnev Doctrine in December 1988 substantively authorized the 1989 Eastern European revolutions, and the cumulative pattern produced the dissolution rather than the reform that Gorbachev intended.
  • (C) Gorbachev's reforms had no significant connection to the eventual dissolution of the Soviet Union.
  • (D) The 1989 Eastern European revolutions were entirely independent of Soviet political developments.
  • (E) The Soviet Union dissolved exclusively through external Western pressure rather than through internal reform dynamics.

Correct: (B). KC-4.2.V.C captures the central pattern: the reforms produced the unintended consequence of accelerating the dissolution rather than producing the reformed system. (A) misreads the historical outcome. (C) misreads the substantial causal connection. (D) misreads the connection between the renunciation of the Brezhnev Doctrine and the 1989 transitions. (E) misreads the principal internal-reform dynamics that the late-Cold-War Western pressure interacted with. (LO G; Skill 3.D; Reasoning Process: Causation).

Short Answer Question ~ 12 min · 1 page
2Question: Using your knowledge of the end of the Cold War between roughly 1985 and 1991, answer all three parts that follow.
  1. Identify ONE specific Gorbachev-era Soviet reform program and what it attempted to accomplish.
  2. Explain ONE specific 1989 Eastern European revolution and the principal mechanism by which Communist Party rule ended in that state.
  3. Explain ONE specific post-1989 European political-territorial reorganization that the collapse of the Soviet Union produced.

Scoring: 1 point for each part. Strong responses to part (a) might cite glasnost (the relaxation of press censorship from 1986 onward); perestroika (the 1987 Law on State Enterprise and the 1988 Law on Cooperatives attempting to introduce market mechanisms); demokratizatsiya (the 19th Party Conference of 1988 and the March 1989 Congress of People's Deputies elections); the renunciation of the Brezhnev Doctrine in Gorbachev's December 1988 UN address; or the May 1985 anti-alcohol campaign (KC-4.2.V.C). Part (b) responses might cite the Polish Round Table negotiations of February-April 1989 and the partially free elections of 4 June 1989; the Hungarian Round Table of June-September 1989; the East German exodus through Hungary and the opening of the Berlin Wall on 9 November 1989; the Czechoslovak Velvet Revolution of 17 November to 29 December 1989 and Vaclav Havel's election as President; the Bulgarian transition of 10 November 1989; or the violent Romanian overthrow of Nicolae Ceausescu on 22-25 December 1989. Part (c) responses might cite the reunification of Germany on 3 October 1990; the Czech-Slovak Velvet Divorce of 1 January 1993; the dissolution of Yugoslavia (Topic 9.5); the Baltic state independence of August 1991; the eastern enlargement of the European Union (10 states in May 2004; Bulgaria and Romania in January 2007; Croatia in July 2013); or the parallel NATO eastern enlargement (KC-4.1.IV.E).

Document-Based Question Stem ~ 60 min · 7 documents
3Prompt: Account for the causes and effects of the end of the Cold War between 1985 and 1991. In your response, draw evidence from the seven documents and from your own knowledge of the period.

The full seven-document set for this DBQ lives in the Unit 9 practice exam packet (Document A: Gorbachev Perestroika book excerpts, 1987; Document B: Gorbachev UN speech, December 1988; Document C: Polish Round Table accord excerpts, April 1989; Document D: Schabowski 9 November 1989 press-conference transcript; Document E: Havel New Year address, January 1990; Document F: August 1991 coup committee announcement; Document G: Belavezha Accords, December 1991).

Scoring framework: 1 point thesis, 1 point contextualization, up to 4 points evidence (at least 3 documents used to support the argument, plus an outside-evidence point), 1 point sourcing (point of view, purpose, situation, audience for at least three documents), 1 point complexity. Maximum 7 points. The default reasoning process is Causation; strong responses identify the cumulative causal chain from Gorbachev's reforms (KC-4.2.V.C) through the 1989 cascade to the eventual dissolution and the post-1989 reorganization (KC-4.1.IV.E). The complexity point is most often earned by examining the multi-perspective documentary record (Soviet reformist; Eastern European transitional; dissolution) and the interactions among the perspectives.

Long Essay Question Stem ~ 40 min
4Prompt: Account for the cascade of 1989 Eastern European revolutions. Why did the Communist Party-led governments collapse in rapid sequence across Poland, Hungary, East Germany, Czechoslovakia, Bulgaria, and Romania between June and December 1989? Defend a clear claim with specific historical evidence.

Scoring framework: 1 point thesis, 1 point contextualization, 2 points evidence (at least two pieces of specific historical evidence, one of which directly supports the argument), 1 point analysis using the Causation reasoning process, 1 point complexity. Maximum 6 points. The complexity point is most often earned by tracing the cascade as a single linked process rather than as six unrelated events. Strong responses identify specific links: Gorbachev's December 1988 UN speech renounced the Brezhnev Doctrine and substantively authorized the subsequent revolutions; the Polish Round Table and June 1989 elections produced the first non-Communist Eastern bloc government and demonstrated that Communist Party-led transitions were possible; the Hungarian-Austrian border opening produced the East German exodus; the East German collapse triggered the Czechoslovak and Bulgarian transitions; the Romanian transition followed last and was the only violent case. The cumulative pattern reflects both the late-Soviet renunciation of the right to intervene and the cumulative political-economic dysfunction of the Eastern bloc that the long pattern of revolt and reimposition (Topic 9.4) had produced. (LO G; Skill 3.D; Reasoning Process: Causation).
