Mikhail Gorbachev became General Secretary of the Soviet Communist Party in 1985, inheriting an economy that had been stagnating for years under the weight of military spending, inefficient central planning, and a costly, unwinnable war in Afghanistan begun in 1979.
His stated goal, from the beginning, was reform intended to save Soviet communism, not to end it. He introduced glasnost, a policy of increased openness that permitted public criticism previously unthinkable under Soviet censorship. And he introduced perestroika, a set of economic restructuring reforms intended to introduce limited market mechanisms into the planned economy, without abandoning socialism itself.
Neither policy achieved its intended economic result. Perestroika's reforms proved too limited to genuinely revive Soviet economic performance while simultaneously disrupting the old command structures enough to worsen shortages in the near term. But glasnost's effect on public discourse and expectation proved far more consequential than its author appears to have anticipated, opening space for criticism that, once permitted, proved difficult to contain within the limits Gorbachev himself had intended.
The single most consequential of Gorbachev's changes, for the states of Eastern Europe specifically, was less a policy announcement than a change in what he was no longer willing to do: unlike his predecessors in 1956 and 1968, examined in chapter forty eight, he made clear, through both private diplomatic signals and eventually public statements, that the Soviet Union would not use military force to prop up unpopular communist governments in the satellite states.
This effective abandonment of the Brezhnev Doctrine removed the single factor that had made every previous Eastern European uprising ultimately unsustainable: the certainty of Soviet tanks. Once Eastern European communist leaders and their own populations both understood, gradually and with initial disbelief, that Moscow would not intervene to save them, the entire calculation underlying four decades of enforced stability changed.
Poland moved first, where the independent trade union Solidarity, founded in 1980 around striking shipyard workers in Gdansk and led by an electrician named Lech Walesa, had survived a period of martial law and suppression in the early 1980s to remain the most organised opposition movement anywhere in the Soviet bloc. Semi-free elections in June 1989, permitted by a nervous Polish communist government hoping to retain a share of power through a negotiated transition, produced a landslide victory for Solidarity candidates in every seat they were permitted to contest, and by September Poland had a non-communist prime minister, the first in the Soviet bloc since the 1940s.
Hungary's own reform communist government moved further and faster than Poland's. It began dismantling its physical border fortifications with Austria in May 1989. This was an act of genuine practical, not merely symbolic, significance, since it opened the first gap in the Iron Curtain's physical infrastructure in decades.
The consequence arrived within months. East German citizens, technically forbidden from travelling to the West but permitted to travel to fellow Warsaw Pact member Hungary, began arriving in Hungary in growing numbers through the summer of 1989, and in September Hungary formally opened its border with Austria, allowing tens of thousands of East Germans to cross into the West within days, an exodus East Germany's own government proved unable to stop without either sealing its border with Hungary, which would have been a humiliating admission of crisis, or reversing Hungary's own decision, which was no longer within East Germany's power to demand.
This hole in the Iron Curtain, opened by Hungary rather than by any action within East Germany itself, did more than any single event to convince East Germans that the system genuinely could be escaped, feeding a growing wave of internal protest, mass demonstrations in Leipzig and other East German cities through the autumn, that the East German government, watching what had happened in Poland and lacking any assurance of Soviet backing for a crackdown, proved unwilling to suppress by force.
The Berlin Wall's actual fall, when it came on the night of the ninth of November 1989, happened through a specific and almost farcical bureaucratic accident rather than through any planned decision to open the border.
East German officials had drafted new, slightly relaxed travel regulations intended to ease, but not eliminate, restrictions on citizens' ability to travel west, planning to announce and implement them gradually over the following days. At a press conference announcing the new rules, a journalist asked spokesman Günter Schabowski when the new regulations would take effect. Schabowski had not been fully briefed on the details or the intended timeline. Checking his notes and finding no specified date, he answered, apparently improvising, that as far as he knew, it was immediate, effective right away.
Within hours, East Berliners, having heard the announcement on television, gathered by the thousands at the wall's checkpoints, demanding entry based on what they had just heard announced. Border guards were confused and increasingly overwhelmed. They received no clear contrary orders from their own superiors. The crowds facing them were too large to control by force, and nobody had given an order to use lethal force. So they simply opened the gates.
Crowds poured through checkpoints that night in scenes broadcast live around the world, and within days ordinary Berliners on both sides were physically dismantling sections of the wall itself with hammers and chisels, souvenir fragments of which are now held in museums and private collections across the globe. A barrier that had stood for twenty-eight years, and that had killed at least a hundred and forty people attempting to cross it, fell in a single night because one tired official misread his own briefing notes.
The Soviet Union's own final collapse in 1991 involved one further dramatic episode worth recounting on its own terms, since it directly shaped who would lead the successor state that mattered most.
In August 1991, a group of hardline Communist Party officials, alarmed at Gorbachev's reforms and at a new treaty he was about to sign granting greater autonomy to the Soviet republics, attempted a coup, placing Gorbachev under house arrest at his holiday residence in Crimea and deploying tanks into Moscow itself.
Boris Yeltsin, the recently elected president of the Russian republic within the Soviet Union and a longtime rival of Gorbachev's own more cautious reformism, defied the coup publicly, climbing onto one of the tanks positioned outside the Russian parliament building to denounce the plotters and rally crowds of ordinary Muscovites to resist, an image broadcast worldwide that became the defining photograph of the coup's collapse within three days.
The coup's failure accelerated rather than prevented the very outcome its plotters had hoped to stop. Gorbachev returned to Moscow to find his own authority fatally undermined, while Yeltsin, whose defiance had made him the coup's genuine hero, emerged as the dominant political figure, and it was Yeltsin, not Gorbachev, who negotiated the Soviet Union's final formal dissolution that December, becoming the first president of an independent Russian Federation.
What makes 1989 genuinely remarkable, set against nearly every previous revolutionary upheaval examined in this book, is how comparatively little violence accompanied the collapse of an entire political and military bloc across an entire continent.
Czechoslovakia's transition, achieved within weeks through a combination of mass demonstrations and negotiations between the communist government and an opposition coalition led by the playwright Vaclav Havel, became known as the Velvet Revolution specifically because of its almost entirely peaceful character, a name that has since been applied more broadly to describe the 1989 transitions generally.
Romania was the significant and bloody exception. Its long-ruling dictator, Nicolae Ceausescu, having built one of the most personalistic and repressive regimes in the Soviet bloc, attempted to suppress protests by force in December 1989, and the resulting violence, including his own hasty televised trial and execution by firing squad on Christmas Day, left over a thousand people dead, the only Eastern European transition of 1989 to involve significant bloodshed on that scale.
The comparative peacefulness elsewhere owed a great deal to the specific combination examined in this chapter: Gorbachev's abandonment of the Brezhnev Doctrine removing the ultimate guarantee of communist rule, ageing Eastern European leaderships who had themselves lost confidence in their own systems' legitimacy, and populations that had, through decades of underground resistance and samizdat networks examined in the previous chapter, organised opposition movements ready to act decisively once the opportunity finally arrived.
Germany itself reunified within less than a year of the wall's fall, formally in October 1990, an outcome that required delicate diplomacy to secure agreement from the Soviet Union, Britain and France, all of whom harboured genuine historical anxiety about a single unified Germany's future power, examined already in chapters forty three and forty five, before finally accepting reunification in exchange for guarantees about a unified Germany's continued NATO membership and permanent renunciation of any further territorial claims.
The Soviet Union itself, having lost its Eastern European buffer states and facing its own accelerating internal economic crisis and nationalist movements within its constituent republics, collapsed entirely by December 1991, dissolving into fifteen separate independent states, the largest and most consequential being the Russian Federation itself, ending, within a period of barely two years, the entire Cold War order examined across the previous two chapters.
Yugoslavia, the independent communist federation noted with its own distinctive path in the previous chapter, did not survive the same period peacefully. Its own internal ethnic and national tensions, held in check for decades by Tito's own authority and by the shared external pressure of the Cold War, erupted into a series of brutal wars through the 1990s as its constituent republics fought over independence and contested borders, producing atrocities, including a genocide at Srebrenica in 1995, that demonstrated the same continent capable of a largely peaceful transition in 1989 was not immune to the kind of mass violence examined throughout this book's earlier chapters.
Firm: the sequence of events across 1989, extensively documented in contemporaneous press coverage, diplomatic archives, and the personal accounts of the many participants and officials who have since written memoirs and given interviews.
Firm: the Schabowski press conference itself, recorded on video and widely available, making it one of the more precisely documented individual moments of accidental historical consequence examined anywhere in this book.
Contested: how much credit Gorbachev's own deliberate policy choices deserve for the peaceful character of the transition, as opposed to broader underlying economic and social pressures that would have produced collapse regardless of his specific decisions, a debate complicated by Gorbachev's own declining domestic popularity within Russia itself in the years since, where many blame him for the Soviet collapse rather than credit him for the transition's relative peacefulness.
A caution about the phrase end of history, coined by the political scientist Francis Fukuyama in an influential 1989 essay arguing that the collapse of communism represented the final ideological triumph of liberal democracy over all rival systems of government. That confident prediction, widely embraced at the time, has aged considerably less well than the events it was written to celebrate, and this book's own final chapter will have occasion to examine why.
