When was the Union of Soviet Socialist Republics (USSR) founded?

The Union of Soviet Socialist Republics (USSR) was founded on December 30, 1922. This foundation was the result of several years of revolutionary upheaval and civil war in Russia. The Russian Revolution of 1917, led by Vladimir Lenin’s Bolsheviks, overthrew the Tsarist regime and established a Communist government.

After the Bolsheviks seized power, civil war broke out between the Reds (Bolsheviks) and the Whites (anti-Bolshevik forces), as well as other groups. This civil war lasted from 1917 to 1923 and ended in victory for the Bolsheviks. On December 30, 1922, the leaders of Soviet Russia, Soviet Ukraine, Soviet Belarus and Soviet Transcaucasia (including Georgia, Armenia and Azerbaijan) signed the treaty creating the USSR, formalizing the union of these socialist republics under a centralized government.

The USSR lasted for almost seven decades and played a major role in twentieth-century world history. It was a superpower, competing with the USA during the Cold War. The USSR influenced many aspects of world politics, economics and culture, while being marked by periods of political repression, economic reform and international conflict.

The Soviet Union collapsed in 1991, marking the end of the Communist era in Eastern Europe and Central Asia, and leading to the independence of its fifteen constituent republics.
