What was the fall of the Soviet Union?
Answer
The 1991 collapse of the communist superpower
Explanation
The fall of the Soviet Union was the political and territorial collapse of the world's largest communist state, which formally dissolved on December 26, 1991, ending the Cold War and ending more than 70 years of communist rule that had begun with the Russian Revolution of 1917. The Union of Soviet Socialist Republics had been a superpower of about 290 million people stretching across 11 time zones from Eastern Europe to the Pacific Ocean.
By the mid-1980s, the Soviet system suffered from a stagnant economy, low productivity, alcohol-fueled social problems, an arms race it could not afford, and the costly invasion of Afghanistan launched in December 1979. Mikhail Gorbachev became General Secretary of the Communist Party on March 11, 1985, the first Soviet leader born after the 1917 revolution, and launched two famous reform policies. Glasnost, meaning openness, allowed greater freedom of speech and the press. Perestroika, meaning restructuring, attempted to introduce limited market mechanisms into the planned economy.
Gorbachev signed the Intermediate-Range Nuclear Forces Treaty with President Ronald Reagan in December 1987, withdrew Soviet troops from Afghanistan in 1989, and refused to use force when Eastern European governments fell in 1989. The reforms unleashed national independence movements inside the Soviet Union itself. The Baltic states of Estonia, Latvia, and Lithuania, annexed by the Soviet Union in 1940, declared independence in 1990 and 1991. Other republics followed.
Hardliners launched a coup against Gorbachev on August 19, 1991, holding him under house arrest at his Crimean dacha. Russian President Boris Yeltsin climbed atop a tank outside the Russian parliament building and rallied resistance, and the coup collapsed within three days. Gorbachev returned to Moscow but had lost his authority. Republic after republic declared independence.
On December 8, 1991, the leaders of Russia, Ukraine, and Belarus signed the Belavezha Accords declaring the Soviet Union dissolved and creating the Commonwealth of Independent States. Eight more republics joined the agreement in Alma-Ata on December 21, 1991. Gorbachev resigned on December 25, 1991. The hammer-and-sickle flag was lowered for the last time over the Kremlin that evening, replaced by the Russian tricolor. The Supreme Soviet voted itself out of existence on December 26, 1991, completing the collapse.
Why this matters for your test
USCIS asks about the fall of the Soviet Union because it ended the Cold War and reshaped American foreign policy for the next generation. Knowing the basic story helps applicants understand why fifteen new independent countries appeared on the world map and why current tensions with Russia echo this earlier era.
