On 30 December 1922, history was irrevocably altered when the creation of the Union of Soviet Socialist Republics (USSR) was formally proclaimed in Moscow from the prestigious Bolshoi Theatre.
The event marked the union of four republics—the Russian, Ukrainian, Byelorussian, and Transcaucasian Soviet Socialist Republics—into a singular political entity poised to redefine geopolitics.
This federation, underpinned by a shared ideological commitment to socialism, emerged as a formidable force, sowing the seeds of a global superpower that would dominate much of the 20th century's political landscape.
