Soviet Union

The Soviet Union, officially known as the Union of Soviet Socialist Republics (USSR), was a federal socialist state that existed from 1922 to 1991. It was a major global power during the 20th century, known for its significant influence in world politics, economy, and military. The Soviet Union played a crucial role in World War II and was a key player in the Cold War, promoting communism as a counter to Western capitalism. Its dissolution in 1991 led to the independence of its constituent republics and marked the end of the Cold War era.
