The End of the Cold War, 1985–1991 (GCSE History)

The Cold War ended between 1985 and 1991 because the Soviet Union reformed itself into collapse. Mikhail Gorbachev's attempts to modernise a stagnant economy loosened controls he could not retighten, Eastern Europe broke away in 1989, and the USSR itself dissolved in December 1991. Whether reform or Western pressure mattered more is still argued.

Where the Cold War stood in 1985

By the mid-1980s the Soviet Union faced problems that had been building for two decades.

• Economic stagnation. Central planning delivered heavy industry and weapons but persistently failed at consumer goods, agriculture and innovation. Shortages and queues were normal; the technology gap with the West was widening.
• Military overstretch. Defence consumed a crippling share of Soviet output, and the war in Afghanistan, entered in 1979, had become a costly and unwinnable commitment.
• Renewed tension. The early 1980s had seen the collapse of détente, a new US arms build-up, and President Reagan's Strategic Defense Initiative — a proposed missile-defence system the USSR could not afford to match.
• Leadership crisis. Three Soviet leaders died between 1982 and 1985, leaving a system that looked as ageing as the men running it.

Gorbachev became General Secretary in March 1985 at fifty-four — a generation younger than his predecessors — convinced the system needed to be saved by reforming it, not replaced.

Gorbachev's reforms

Two Russian words carry most of the explanation, and getting them right is worth marks.

Perestroika — "restructuring" — was economic. It allowed limited private enterprise, gave factory managers more autonomy and reduced central planning. In practice it produced the worst of both worlds: enough disruption to break the old system's routines, not enough freedom to let a new one function. Shortages worsened.

Glasnost — "openness" — was political and cultural. Censorship was relaxed, past crimes including Stalin's purges were discussed publicly, criticism of officials became possible and contested elections were introduced. This is the reform that proved uncontainable. Once people could say what was wrong, the list turned out to be long, and grievances in the Soviet republics — Baltic, Caucasian, Central Asian — surfaced as demands for independence.

Alongside these, Gorbachev cut foreign commitments. Soviet forces withdrew from Afghanistan, completing in 1989, and he made clear that the USSR would no longer use force to prop up communist governments in Eastern Europe — a reversal of the Brezhnev Doctrine that a Soviet spokesman jokingly renamed the Sinatra Doctrine, because each country could now do it "their way".

Arms control and the thaw with the West

Gorbachev and Reagan met repeatedly, and the trajectory of those summits is a clean narrative for an exam answer.

The INF Treaty mattered beyond the weapons themselves: it was the first agreement to abolish rather than merely limit a category of nuclear weapons, and it included intrusive mutual inspections, which required a degree of trust unimaginable a decade earlier.

The revolutions of 1989

Once it was clear that Soviet tanks would not arrive, the communist governments of Eastern Europe fell in barely a year.

• Poland. Solidarity, the independent trade union suppressed in 1981, was legalised and won a crushing victory in partially free elections in June 1989, forming the first non-communist-led government in the bloc.
• Hungary. Reformers dismantled the fortified border with Austria, opening a route westward that thousands of East Germans used.
• East Germany. Mass demonstrations, particularly in Leipzig, grew weekly. A confused announcement about travel rules brought crowds to the crossings on 9 November 1989, and the Berlin Wall was opened.
• Czechoslovakia. The Velvet Revolution brought down the government within weeks, with the dissident playwright Václav Havel becoming president.
• Romania. Alone among them, the change was violent: Nicolae Ceaușescu was overthrown and executed in December 1989.

Germany was formally reunified on 3 October 1990. The Warsaw Pact, the Soviet military alliance, was dissolved in 1991.

The collapse of the Soviet Union

The final act was internal. Nationalist movements in the republics — beginning with the Baltic states, which had never accepted their 1940 annexation — pressed for independence, and Gorbachev's attempts to hold the union together satisfied neither reformers nor hardliners.

In August 1991, communist hardliners attempted a coup, detaining Gorbachev in Crimea. It collapsed within days, partly because of public resistance in Moscow led visibly by Boris Yeltsin, the president of the Russian republic. The coup destroyed what remained of the Communist Party's authority and of Gorbachev's own. Republics declared independence in quick succession, and the Soviet Union was formally dissolved at the end of December 1991, with Gorbachev resigning as its last leader.

What ended the Cold War? The historical debate

This is the evaluation question, and it has three respectable answers.

Gorbachev's reforms. The strongest single-factor case. He removed the threat of Soviet intervention, without which the 1989 revolutions could not have happened peacefully. Every alternative explanation still has to pass through his decisions.

Western pressure. Some historians argue the American military build-up and the Strategic Defense Initiative forced the USSR into a competition it could not afford, making reform unavoidable. Critics reply that Soviet defence spending did not rise sharply in response, and that Reagan's later willingness to negotiate mattered more than his earlier confrontation.

Internal weakness. A third view holds that the Soviet economy was failing regardless — that stagnation, the technology gap and the cost of empire made collapse a matter of when rather than whether, and that Gorbachev merely determined the timing and the relative peacefulness.

A strong conclusion combines them with a ranking: long-term economic weakness created the necessity, Western pressure sharpened it, and Gorbachev's choices determined that the ending was negotiated rather than fought. Note also the role of ordinary people — the crowds in Leipzig, the shipyard workers of Gdańsk, the Muscovites facing down the coup — which single-leader explanations tend to leave out.

Frequently asked questions

Why did Gorbachev not use force to stop the 1989 revolutions?

Because his whole strategy depended on not using it. Military intervention would have destroyed the relationship with the West that he needed for arms reductions and economic help, and it would have cost money the Soviet Union did not have at exactly the moment he was trying to cut foreign commitments. He also appears to have believed genuinely that socialism could be reformed with popular consent rather than imposed, and that regimes surviving only on Soviet bayonets were a liability. Whether he anticipated how completely they would fall once that guarantee was withdrawn is doubted by many historians — the speed of 1989 surprised almost everyone.

Did the Berlin Wall fall by accident?

The pressure behind it was entirely deliberate, but the timing on the night owed a good deal to confusion. Months of mounting demonstrations and an exodus of East Germans through Hungary had already made the situation unsustainable. On 9 November 1989 an East German official announced new travel regulations at a press conference and, pressed on when they took effect, indicated immediately — apparently without full authority. Crowds gathered at the crossing points, and guards, without clear orders and facing overwhelming numbers, opened the gates. The accident was in the hour, not in the outcome.

Was the end of the Cold War a Western victory?

It depends what you mean by victory, which is exactly why the question is set. The Western system survived and the Soviet one did not, and NATO expanded eastwards afterwards, so in outcome terms the claim is defensible. But the Soviet Union was not defeated militarily, and the decisive choices — to reform, to withdraw, not to shoot — were taken in Moscow rather than forced from outside. Gorbachev himself argued he had ended a dangerous confrontation rather than lost one. Many Russians experienced the following decade as economic catastrophe and national humiliation, which is part of why this history remains politically live today.

How much detail do I need on the individual 1989 revolutions?

Enough to name at least two countries with specific detail rather than describing "Eastern Europe" in general. Poland and East Germany are the most useful pair: Poland shows the process beginning through elections and an organised opposition movement, East Germany shows mass protest and the symbolic collapse of the Wall, and Romania provides a valuable contrast as the one violent case. Precise, named examples are what separate the top bands from competent narrative, and three well-known cases are far more useful than a hazy list of six.
