USSR

The USSR, or Union of Soviet Socialist Republics, was a federal socialist state that existed from 1922 to 1991. It was made up of multiple republics, with Russia being the largest. The USSR was founded after the Russian Revolution, aiming to create a society based on communist principles. It became a major world power, influencing global politics, economics, and culture, especially during the Cold War against the United States. The government was characterized by central planning and a single-party system. In 1991, it dissolved into independent countries, marking the end of its communist regime.
