Soviet Union

• 1. Revolutionary Origins And Formation

  ›

  In November 1917, Vladimir Lenin led the Bolsheviks to seize power from the Provisional Government in Petrograd. Workers and soldiers had formed councils known as soviets during the February Revolution of that same year. These groups demanded an end to World War I and land redistribution for peasants. The October Revolution established the Russian Socialist Federal Soviet Republic, the world's first constitutionally communist state. A brutal civil war followed immediately, pitting Red Army forces against White Army counter-revolutionaries. Millions died in the conflict, which lasted until 1923. By December 1922, the Russian SFSR merged with other republics to form the Union of Soviet Socialist Republics. Joseph Stalin initially resisted Lenin's proposal for a unified union but eventually accepted it. The new state spanned eleven time zones and shared borders with twelve countries.

• 2. Stalinist Industrialization And Purges

  ›

  Joseph Stalin came to power following Lenin's death in 1924. He abandoned the New Economic Policy by 1928 and pushed for full central planning. Forced collectivization of agriculture began shortly after, causing a famine between 1930 and 1933 that killed millions. Resources were mobilized for rapid industrialization, transforming the USSR from an agrarian economy into a great industrial power. The Soviet forced labour camp system of the Gulag expanded significantly during this period. During the late 1930s, Stalin's government conducted the Great Purge to remove opponents. Large scale deportations, arrests, and show trials accompanied public fear. The NKVD secret police played a key role in these operations. Stalin controlled all foreign relations of the Soviet Union during the interwar period.

• 3. World War II Eastern Front

  ›

  In August 1939, the Soviet Union signed a non-aggression pact with Nazi Germany known as the Molotov-Ribbentrop Pact. Despite this agreement, Germany invaded the Soviet Union in June 1941 in Operation Barbarossa. This marked the largest land invasion in history and opened the Eastern Front of World War II. The Soviets suffered an estimated 27 million casualties, which accounted for most losses among the victorious Allies. They played a decisive role in defeating the Axis powers while liberating much of Central and Eastern Europe. After the war, the Soviet Union consolidated territory occupied by the Red Army. Millions died in the conflict, including excess deaths throughout World War I and the Russian Civil War that amounted to 18 million combined.

• 4. Cold War Superpower Dynamics

  ›

  Geopolitical tensions with the United States led to the Cold War beginning in 1945. The American-led Western Bloc coalesced into NATO in 1949. The Soviet Union formed its own military alliance, the Warsaw Pact, in 1955. Neither side engaged in direct military confrontation, fighting instead on an ideological basis through proxy wars. The Warsaw Pact's primary function was to safeguard the Soviet Union's hegemony over its Eastern European satellites. Stalin used Cominform to coordinate actions between Marxist-Leninist parties under Soviet direction. The Soviet Union also began the war in Afghanistan between 1979 and 1989. During the Cuban Missile Crisis, the Soviet navy expanded significantly under Sergei Gorshkov's leadership.

• 5. Space Race Technological Achievements

  ›

  At the end of the 1950s, the USSR constructed Sputnik 1, marking the beginning of the Space Race. On the 12th of April 1961, the USSR launched Vostok 1, carrying Yuri Gagarin as the first human to ever be launched into space. Valentina Tereshkova became the first woman in space during a later mission. In the late 1980s, the Soviet Union built the Mir orbital station, which operated from 1986 to 1998. The N1 launch vehicle failed all four test launches intended for a crewed moon landing. The Buran shuttle flew in 1988 without a human crew. The Energia rocket remains one of the most powerful in the world today. Soviet scientists were among the world's best-trained specialists in space technology by 1989.

• 6. Economic Command System And Decline

  ›

  The Soviet Union adopted a command economy where production and distribution were centralized by the government. Gosplan organized economic activity through five-year plans starting in the 1930s. Heavy industry and defence were prioritized over consumer goods throughout the Cold War. Grain and sophisticated consumer manufactures became major import articles from around the 1960s. Military expenditures formed 40, 60% of the entire federal budget in the 1970s. By 1987, Mikhail Gorbachev attempted to reform the economy with perestroika policies. His reforms relaxed state control but resulted in a sharp decline in output. Prices remained fixed until after the country's dissolution in late 1991.

• 7. Gorbachev Reforms And Dissolution

  ›

  In 1985, Mikhail Gorbachev sought to reform the country through glasnost and perestroika policies. In 1989, various countries of the Warsaw Pact overthrew their Soviet-backed regimes. A major wave of nationalist movements erupted across the Soviet Union, primarily in Azerbaijan, Georgia, and the Baltic states. On 19, the 21st of August 1991, hardline communists staged a failed coup attempt against Gorbachev. The largest republics, Ukraine, Russia, and Belarus, seceded following this event. Boris Yeltsin oversaw the reconstitution into the Russian Federation on the 26th of December 1991. Gorbachev officially recognized the dissolution of the Soviet Union that same day. The Commonwealth of Independent States formed in the aftermath, though the Baltics never joined.
