Soviet Union

The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a federal socialist state in Northern Eurasia that existed from 1922 to 1991. It was a union of several Soviet Republics under the leadership of its Communist Party. The republics acted in a similar way to the constituent countries of the United Kingdom or the States of the United States. It bordered 16 other countries, Norway, Finland, Poland, Czechoslovakia, Hungary, Romania, Turkey, Iran, Afghanistan, China and North Korea. It also had close maritime boundaries with Japan and the United States.

History
The Soviet Union was created on December 30, 1922, after Vladimir Lenin and the Bolsheviks overthrow the Russian Government and win the Russian Civil War. Lenin died and was replaced by Joseph Stalin. In August 1939, the Soviet Union signed a non-aggression pact with Nazi Germany: they agreed to divide up Eastern Europe and supply each other. In late 1939, the Soviets fought a war against Finland for months and ended up annexing pieces of Finland. The Soviet Union annexed several other countries. On June 22, 1941, Nazi Germany invaded the Soviet Union, but the Soviets defeated the Nazis in 1945. Then, the Soviet Union and the United States developed a rivalry, which eventually lead to a Cold War. The Soviets tested their first nuclear bomb, called RDS-1, on Semipalatinsk, Kazakh SSR (now Kazakhstan). The USSR supported communists around the war in several proxy wars to counter capitalist countries. It also created the Warsaw Pact in 1955, which consisted of itself, Poland, Czechoslovakia, Hungary, Romania, Bulgaria, and East Germany. Later, the USSR and America strengthened their relationship with each other, known as Détente. However, tensions rose during the Euromissile Crisis between 1977 and 1982. The Soviets invaded Afghanistan in 1979 but lost in 1989. Mikhail Gorbachev, the new leader, implemented two major policies in the Soviet Union: Glasnost and Perestroika. He also improved relations with the US. From March 1990 to December 26, 1991, the fifteen Soviet republics declared themselves independent and the Soviet Union collapsed.
