Mikhail Gorbachev was the last leader of the Soviet Union (1985-1991), whose reforms of glasnost (openness) and perestroika (restructuring) were meant to fix a stagnant communist system but instead unleashed forces that collapsed the USSR and ended the Cold War.
Mikhail Gorbachev became General Secretary of the Communist Party in 1985 and later served as the first (and only) President of the Soviet Union. He inherited a country in deep trouble. After decades of economic stagnation under Brezhnev, the Soviet command economy couldn't keep up with the West, and the arms race was bleeding the budget dry. Gorbachev's answer was two famous reforms. Perestroika restructured the economy by loosening central planning and allowing limited market activity. Glasnost opened up political life, easing censorship and letting people criticize the government for the first time in generations.
Here's the irony the AP exam loves. Gorbachev was trying to save communism, not kill it. But per the CED (KC-4.2.V.C), his reforms "failed to stave off the collapse of the Soviet Union." Once people could speak freely, they demanded more than reform. Gorbachev also refused to send tanks into Eastern Europe when satellite states revolted in 1989, effectively abandoning the Brezhnev Doctrine. The Berlin Wall fell, the satellites broke free, and in 1991 the USSR itself dissolved, ending the Cold War.
Gorbachev lives in Unit 9 (Cold War and Contemporary Europe) and is the central figure for Topic 9.7, The Fall of Communism. Learning objective 9.7.A asks you to explain the causes and effects of the end of the Cold War, and Gorbachev is named directly in the essential knowledge (KC-4.2.V.C). He also matters for 9.1.A and 9.3.A, since you can't explain how the Cold War ended without him. The big analytical move the exam wants is understanding unintended consequences. Gorbachev's reforms were designed to make the Soviet system "more flexible," but they triggered its collapse instead. That cause-and-effect chain (stagnation → reform → collapse → capitalist economies across Eastern Europe, German reunification, EU enlargement) is straight from KC-4.1.IV.E and is exactly what an LEQ or SAQ on the end of the Cold War would reward.

Glasnost and Perestroika (Unit 9)
These are Gorbachev's signature policies and the terms the exam pairs with his name. Perestroika tried to fix the economy; glasnost tried to fix trust in the government. Both ended up exposing how broken the system was.
Dissolution of the Soviet Union (Unit 9)
Gorbachev's reforms are the direct cause, the 1991 dissolution is the effect. The CED frames it bluntly. The reforms "failed to stave off the collapse," so any essay on the USSR's end starts with Gorbachev.
Brezhnev Doctrine (Unit 9)
Brezhnev promised Soviet military force to keep satellite states communist. Gorbachev quietly dropped that promise, which is why the 1989 revolutions in Eastern Europe succeeded where Hungary 1956 and Prague 1968 had been crushed.
De-Stalinization (Unit 9)
Khrushchev's de-Stalinization in the 1950s was an earlier attempt at reform-from-above that loosened control without abandoning communism. Gorbachev is the same playbook taken much further, and this time the system didn't survive it. Great continuity-and-change pairing.
Gorbachev shows up most often in multiple-choice questions about the end of the Cold War. Stems typically ask what caused him to launch glasnost and perestroika (answer: long-term economic stagnation), what perestroika's primary goal was (restructuring the Soviet economy, not ending communism), or which leader's policies contributed to the Cold War's end. For free-response writing, Gorbachev is your go-to evidence for any prompt on the causes of the Cold War's end or the collapse of communism in Eastern Europe. The strongest move is explaining the unintended-consequences argument. He reformed to preserve the system, and the reforms destroyed it. Pair him with the fall of the Berlin Wall in 1989 as the symbolic turning point and the 1991 dissolution as the endpoint, and you've got a clean causation chain.
Gorbachev led the Soviet Union and tried to reform communism from within. Yeltsin led Russia (one republic inside the USSR) and pushed to scrap the Soviet system entirely. When the USSR dissolved in December 1991, Gorbachev resigned and Yeltsin became the leader of the new, post-Soviet Russia. Easy way to remember it is that Gorbachev ended the Cold War; Yeltsin took over what was left.
Gorbachev led the Soviet Union from 1985 to 1991 and introduced glasnost (political openness) and perestroika (economic restructuring) in response to decades of economic stagnation.
His goal was to make the Soviet system more flexible and save communism, but the reforms instead accelerated the collapse of the USSR, the classic unintended-consequences argument the exam rewards.
By abandoning the Brezhnev Doctrine, Gorbachev let the 1989 revolutions in Eastern Europe succeed without Soviet military intervention, ending Soviet control over its satellite states.
The collapse of the USSR in 1991 ended the Cold War and led to capitalist economies across Eastern Europe, German reunification, and the eventual enlargement of the European Union.
On the exam, Gorbachev is your strongest evidence for any question about the causes and effects of the end of the Cold War (learning objective 9.7.A).
As Soviet leader from 1985 to 1991, Gorbachev introduced glasnost (openness) and perestroika (economic restructuring) to fix a stagnant Soviet system. The reforms loosened control so much that the satellite states broke free in 1989 and the USSR itself dissolved in 1991, ending the Cold War.
No. Gorbachev was a committed communist trying to reform and preserve the Soviet system, not destroy it. The CED frames his reforms as designed to make the system "more flexible," and their failure to save it is the unintended consequence AP Euro wants you to explain.
Glasnost was political openness, easing censorship and allowing public criticism of the government. Perestroika was economic restructuring, loosening central planning and permitting limited market activity. A quick memory trick is that glasnost is about speech and perestroika is about the economy.
Khrushchev's de-Stalinization in the 1950s loosened repression but kept tight party control, and the USSR survived it. Gorbachev's reforms in the 1980s went much further, allowing real political criticism and refusing to use force in Eastern Europe, and the system collapsed. That contrast makes a strong continuity-and-change argument.
Perestroika disrupted the command economy without building a working market to replace it, so shortages got worse. Meanwhile glasnost let people openly demand independence and democracy. Combined with his refusal to crush the 1989 revolutions, the reforms unleashed pressures the Soviet system couldn't contain, and the USSR dissolved in 1991.
