The Union of Soviet Socialist Republics, often called the USSR, was a massive transcontinental country. It spanned much of Eurasia from 1922 until its dissolution in 1991.

At its largest, it was the world's biggest country by land area. It covered about one-sixth of the Earth's total land surface. This made its size comparable to the entire continent of North America. The USSR was a diverse multinational state made of many national republics. The largest and most populous of these was the Russian Soviet Federative Socialist Republic. Its capital and main center was the city of Moscow.

The word "soviet" comes from the Russian word *sovet*, meaning "council" or "assembly."

These councils first appeared during the 1905 Russian Revolution. Later, workers and soldiers formed soviets to share power. After the October Revolution in 1917, Vladimir Lenin led a new government. He established the Russian SFSR as the first constitutionally communist state. In 1922, the Russian SFSR and other subordinate republics merged. This merger created the official Soviet Union. The government was a one-party state run by the Communist Party. Most power was highly centralized in the hands of the central government.

Leadership changed significantly after Lenin's death in 1924. Joseph Stalin rose to power and began a period of intense change. He pushed for rapid industrialization and forced collectivization of agriculture. While these moves grew the economy, they also caused a massive famine in the 1930s. Millions of people died during this time. Stalin also used the Gulag system, which was a network of forced labor camps. In the late 1930s, he conducted the Great Purge. This involved executions, deportations, and show trials to remove perceived enemies. The state became highly centralized and totalitarian under his rule.

The Soviet Union played a decisive role in World War II. In 1939, the USSR signed a non-aggression pact with Nazi Germany. However, Germany invaded the Soviet Union in 1941. This was the largest land invasion in history and opened the Eastern Front.

The Red Army fought to defeat the Axis powers. They eventually liberated much of Central and Eastern Europe. The human cost was enormous, with approximately 27 million Soviet casualties. After the war, the USSR became a global superpower. It consolidated many occupied territories into satellite states.

After the war, the world entered the Cold War. This was a period of intense geopolitical tension with the United States. The US led the Western Bloc and formed NATO in 1949. In response, the Soviet Union led the Eastern Bloc and formed the Warsaw Pact in 1955.

The two sides fought through ideological battles and proxy wars. In 1953, Nikita Khrushchev began a process called de-Stalinization. This era of relative openness was known as the Khrushchev Thaw. However, tensions remained high. The Soviet military even suppressed uprisings in countries like Hungary and Czechoslovakia.

By the 1970s, the Soviet Union faced growing internal problems. Under Leonid Brezhnev, the country entered an era of stagnation. This period was marked by economic decline and political corruption. The economy struggled due to its centralized nature and technological gaps. Vast military spending also strained the nation's resources. In 1985, Mikhail Gorbachev took power and tried to fix these issues. He introduced *glasnost*, which meant openness, and *perestroika*, which meant restructuring.

Instead of fixing the system, these reforms accelerated its collapse.

The end of the Soviet Union happened very quickly in the late 1980s and early 1990s. In 1986, the Chernobyl nuclear disaster caused a massive socio-economic crisis. By 1989, most Warsaw Pact countries overthrew their Soviet-backed governments. Nationalist movements grew strong within the Soviet republics themselves. Following a failed coup by hardliners in August 1991, the union began to break apart. Russia, Ukraine, and Belarus eventually moved to secede. On December 26, 1991, Gorbachev officially recognized the dissolution. The USSR was replaced by many independent states, with the Russian Federation acting as its successor state.
