Gorbachev & the Collapse of the Soviet Union
Gorbachev’s “New Thinking”
In March 1985, Mikhail Gorbachev became the leader of the Soviet Union. At 54, he was much younger than his predecessors and brought a fundamentally different approach to governing. Gorbachev recognised that the Soviet Union was in deep trouble: the economy was stagnating, the war in Afghanistan was draining resources and morale, the arms race was cripplingly expensive, and ordinary Soviet citizens faced shortages of basic goods.
Gorbachev introduced what he called “new thinking” — a willingness to reform the Soviet system and to negotiate with the West rather than confront it. His two signature policies were glasnost (openness) and perestroika (restructuring).
Glasnost meant greater freedom of speech, press freedom and political debate. Perestroika meant reforming the economy by reducing central planning and introducing some market-based elements. Gorbachev wanted to modernise the Soviet system, not destroy it — but his reforms ultimately unleashed forces he could not control.
Reducing Cold War Tensions
Gorbachev and Reagan developed a surprisingly productive relationship. Despite their ideological differences, both leaders recognised the need to reduce the nuclear threat. They held a series of summit meetings that transformed the Cold War.
Geneva Summit
Gorbachev and Reagan met for the first time. No major agreements were reached, but the two leaders established a personal rapport and agreed to hold further meetings.
Reykjavik Summit
Gorbachev proposed eliminating all nuclear weapons within ten years. The talks collapsed because Reagan refused to abandon SDI. However, the summit showed both sides were serious about major arms reductions.
INF Treaty
Gorbachev and Reagan signed the Intermediate-Range Nuclear Forces Treaty, eliminating all land-based nuclear missiles with ranges between 500 and 5,500 kilometres. This was the first treaty to actually reduce (not just limit) nuclear weapons. Nearly 2,700 missiles were destroyed.
Previous agreements (SALT 1, SALT 2) had only limited the growth of nuclear arsenals. The INF Treaty was the first to require the actual destruction of nuclear weapons — nearly 2,700 missiles were eliminated. It included on-site inspections to verify compliance, demonstrating a level of trust that would have been unthinkable a decade earlier. The treaty removed an entire class of weapons from Europe and showed that genuine disarmament was possible.
Impact on Eastern Europe
Gorbachev’s reforms had a transformative effect on Eastern Europe. He made clear that the Soviet Union would no longer use force to keep communist governments in power — effectively abandoning the Brezhnev Doctrine. This was sometimes called the “Sinatra Doctrine” (after Frank Sinatra’s song “My Way”) — satellite states could now go their own way.
Without the threat of Soviet military intervention, opposition movements across Eastern Europe gained momentum. In Poland, Solidarity won all the seats it contested in the partly free June 1989 elections. In Hungary, the government opened its border with Austria, allowing East Germans to flee west. In Czechoslovakia, the “Velvet Revolution” peacefully removed the communist government. In Romania, the dictator Ceauşescu was overthrown and executed.
The Fall of the Berlin Wall
On 9 November 1989, the Berlin Wall was opened. The East German government, overwhelmed by mass protests and the flood of citizens leaving through Hungary, announced that citizens could cross the border freely. Thousands of jubilant Berliners climbed onto the Wall and began tearing it down with hammers and picks. The event was broadcast live around the world and became the defining image of the end of the Cold War.
The fall of the Berlin Wall on 9 November 1989 symbolised the end of communist control in Eastern Europe. Germany was formally reunified on 3 October 1990. The Wall that had divided East and West for 28 years was gone.
The Collapse of the Soviet Union
Gorbachev’s reforms, intended to save the Soviet system, ultimately destroyed it. Glasnost allowed people to criticise the government openly for the first time, and many demanded independence for their republics. Perestroika failed to deliver economic improvement, increasing public frustration. Nationalist movements surged in the Baltic states (Lithuania, Latvia, Estonia), Ukraine, and other Soviet republics.
In August 1991, hardline communists attempted a coup against Gorbachev, fearing his reforms had gone too far. The coup failed, largely because Boris Yeltsin (President of the Russian Republic) rallied opposition. However, the failed coup fatally weakened Gorbachev’s authority. One by one, Soviet republics declared independence.
The Warsaw Pact was formally dissolved on 1 July 1991, as its member states had already abandoned communism. On 25 December 1991, Gorbachev resigned as President of the Soviet Union. The following day, 26 December 1991, the Soviet Union was officially dissolved, splitting into 15 independent states. Russia, under Boris Yeltsin, emerged as the largest successor state. The Cold War was over after 46 years.
The Cold War ended not with a military victory but with the internal collapse of the Soviet system. Gorbachev’s reforms, Reagan’s economic pressure, the arms race burden, the Afghan war, nationalist movements, and the fundamental weaknesses of the communist command economy all contributed to the dissolution of the USSR on 26 December 1991.
