What happened

The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a transcontinental country that spanned much of Eurasia from its formation in 1922 until its dissolution in 1991. It was the world's third-most populous country, the largest by area, and bordered twelve other countries. A diverse multinational state, it was organized as a federal union of national republics, with the largest and most populous being the Russian Soviet Federative Socialist Republic (SFSR).
