Soviet Union

The Soviet Union, or U.S.S.R, was a grouping of countries which existed on Earth during the 20th century. Russia was part of the U.S.S.R. and, as such, the Russian language was extensively spoken by its peoples. Ukraine and Kazakhstan were also parts of the Soviet Union. (AUDIO: Thin Ice, 1963: The Space Race) East Germany also joined the Soviet Union following the seperation of Germany after the Second World War. (AUDIO: Protect and Survive)

Alternative timelines
In an alternative timeline in which Nazi Germany won World War II as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Nazi scientists were able to refine uranium and create nuclear weapons. They subsequently bombed Moscow, forcing the surrender of the Soviet Union and winning the war for Germany. (AUDIO: Klein's Story)

In an alternative timeline created by the Elder Gods in the hope of destroying Earth, Vladimir Kryuchkov became the Soviet General Secretary instead of Gorbachev in 1985. On 9 November 1989, World War III broke out between the Soviet Union on the one hand and the United States and its allies, including the United Kingdom, on the other hand. Given that nuclear weapons were used by both sides, hundreds of millions of people were killed in the conflict. This timeline was ultimately negated by the Seventh Doctor.

Behind the scenes

 * To describe events throughout the second half of the 20th century, the names "Russia" and "Soviet Union" are often used interchangeably, but are in fact separate. Although the biggest by far, Russia was only one of several republics that formed the Union.
 * In the real world, the Soviet Union was created in 1922 and dissolved in 1991.
