§Text Passage
1In 1985 Gorbachev became General Secretary of the Soviet Communist Party and launched two great reforms: glasnost and perestroika. Glasnost relaxed controls on speech and publication, allowing open criticism of past policy errors; perestroika attacked the rigid planned economy by introducing limited market elements. Yet restructuring failed to ease shortages and living standards fell; long-suppressed grievances surfaced and nationalism rose in the republics — the reforms accelerated the very collapse they were meant to prevent.
2Gorbachev also gave up interfering in Eastern Europe, and the region slipped out of control. In 1989 Poland's Solidarity movement was allowed to compete and won; Hungary opened its border to the West; East Germans fled and protested in huge numbers, and on 9 November the Berlin Wall was breached by the crowds. The Velvet Revolution in Czechoslovakia and the fall of Romania's regime followed, and within a year communist rule across Eastern Europe had ended.
3The upheaval then reached the Soviet Union itself: the two Germanys united in October 1990; in August 1991 communist hardliners staged a coup and held Gorbachev captive. The coup failed, Russian President Yeltsin emerged stronger, and the republics declared independence one after another. On 25 December 1991 Gorbachev resigned, the Soviet Union formally dissolved into fifteen independent states, many of which joined the Commonwealth of Independent States — the Cold War was over.
4The post-Cold War world took a new shape: the United States stood as the only superpower and the international system turned unipolar for a time; the UN's peacekeeping role expanded and NATO enlarged to absorb former Soviet-bloc members; global trade and international organisations knit the world closer. Yet the new order was uneasy: regional conflicts such as the Balkan wars multiplied, terrorism rose, and the attacks of 11 September 2001 revealed new non-traditional threats — the international order has had to keep adapting.

On 3 October 1990 East and West Germany ended their division and merged into one state.
In December 1991 the USSR ended and its fifteen republics became independent states, closing the Cold War.

3Step by step Steps
- Step 1: Gorbachev and glasnostWhen Gorbachev took over in 1985, growth had stalled, the bureaucracy was rigid, and the arms race with America strained finances. Glasnost relaxed censorship: newspapers could openly criticise mistakes made since Stalin's era, and banned writers were republished. For example, the Chernobyl nuclear disaster of 1986, once unspeakable, was pursued by the press for days; official prestige suffered and long-suppressed grievances surged, sending the reform quickly out of control.
- Step 2: The troubles of perestroikaPerestroika tried to inject market elements into the planned economy: enterprises gained autonomy, some private activity was allowed and some prices released. For example, unbalanced investment persisted, subsidies were not cut while curbs on alcohol sales slashed tax revenue, and falling oil prices drained hard currency; shortages worsened and citizens queued for food, blaming the reforms. Economic distress shook the republics' loyalty to the centre — the economic root of the collapse.
- Step 3: The 1989 upheavals in Eastern EuropeGorbachev renounced interference in Eastern Europe, and once the Soviet umbrella was lifted, change erupted across the region. For example, Poland's Solidarity won the partly free elections of June 1989; Hungary opened its border with Austria and East Germans fled west, protests in Leipzig swelled, and on 9 November the Berlin Wall was breached; Czechoslovakia's Velvet Revolution changed power peacefully and Romania's dictatorship also fell. Within a year communist rule in Eastern Europe had ended.
- Step 4: German reunification and the Soviet collapseAfter the Wall fell, calls for unity surged, and Germany united in October 1990 — the Cold War's central symbol in Europe was gone. Inside the USSR, hardliners launched a coup in August 1991 and held Gorbachev captive; Yeltsin rallied resistance from atop a tank, the coup failed in three days, but central authority was bankrupt. For example, the Baltic states led the way to recognised independence; in December Russia, Ukraine and Belarus signed an agreement forming the CIS, and on 25 December Gorbachev resigned as the USSR dissolved.
- Step 5: Post-Cold War international cooperationThe Cold War's end opened space for cooperation. With great-power coordination the UN Security Council passed landmark resolutions, and in the 1991 Gulf War a multinational force was authorised to expel Iraq from Kuwait — a signature case of collective security; arms control moved from limits to reductions as Washington and Moscow signed START; the World Trade Organization was founded in 1995 as globalisation accelerated. For example, UN peacekeeping operations multiplied in the 1990s — international organisations became pillars of the new order.
- Step 6: US unipolarity and NATO enlargementAfter the Soviet collapse the United States stood alone as the superpower, unmatched in military, economic and cultural influence — a unipolar moment. NATO enlarged step by step: Poland, the Czech Republic and Hungary in 1999, and in 2004 the Baltic states and other former Soviet-bloc members. For example, NATO bombed Yugoslavia during the Balkan crises of the 1990s, showing the alliance's military role grew rather than shrank, while Russia saw enlargement as a security threat — sowing the seeds of later tension.
- Step 7: The worries and balance of the new orderThe post-Cold War order mixed gains and harms: on the credit side great-power confrontation ended, cooperative organisations expanded and global trade flourished; on the debit side unipolarity lacked checks, and regional conflicts and humanitarian disasters multiplied. For example, the Balkan wars of the 1990s and the Rwandan genocide of 1994 exposed slow international responses, and the 11 September 2001 attacks showed terrorism had become a new global threat, leading to America's war in Afghanistan. Evaluate the order with both sides — avoid one-way conclusions.
5Worked example Example
Essay question: some argue that the Soviet collapse stemmed mainly from internal causes. Trace the chain of causes behind the dissolution of the USSR, and give your view on whether the post-Cold War international order has done more good than harm to the world.
- Build a chain first: start with the deep causes — economic stagnation and a rigid system — add the catalyst of reform, and finish with the failed coup and the collapse of central authority, showing a progressive causal chain
- Deep causes: an inefficient planned economy, the crushing burden of the arms race and long-suppressed nationality problems made the system fragile
- Catalysts: glasnost unleashed criticism and nationalism, perestroika worsened economic chaos; after Moscow gave up intervening in Eastern Europe, the 1989 upheavals set a demonstration effect that emboldened the republics
- The final link: the failed August 1991 coup destroyed the party's prestige, the centre lost control of the regions, and the USSR dissolved in December
- Weigh good and harm: gains — great-power cooperation, expanded UN peacekeeping and the prosperity of globalisation; harms — regional conflicts, rising terrorism and an unchecked unipolar system; conclude with both sides, noting the order is still evolving
- Answer: The Soviet collapse was a chain of interlocking causes: a long-inefficient planned economy, an arms race that drained finances and accumulated nationality problems left the system deeply fragile. Gorbachev's glasnost and perestroika from 1985 were meant as self-rescue, but glasnost unleashed criticism and nationalism while perestroika deepened shortages; having renounced intervention in Eastern Europe, he watched the 1989 upheavals topple communist regimes, the Berlin Wall fall and Germany unite in 1990 — a demonstration effect that pushed the republics towards independence. After the failed coup of 1991 central authority collapsed; Gorbachev resigned in December and the USSR dissolved. As for the post-Cold War order, the gains were the end of confrontation, an enlarged role for the UN and cooperation, and the prosperity of globalisation; the harms were unchecked US unipolarity, regional conflicts from the Balkans to Rwanda, and terrorism that became a global threat after 11 September 2001. On balance the new order brought opportunities and new dangers alike — its benefits and costs coexist and the order is still evolving.
