USSR (Union of Soviet Socialist Republics)

The USSR, or the Union of Soviet Socialist Republics, was a federation of multiple republics that existed from 1922 to 1991. It was a socialist state led by the Communist Party, advocating for collective ownership and state control of resources and industries. The USSR played a significant role in global politics, especially during the Cold War, opposing the United States and its allies. Its economy was centrally planned, which led to rapid industrialization but also significant challenges. The USSR dissolved in 1991, resulting in the independence of its republics and significant geopolitical changes.
