When was the Soviet Union formally established, and what did it consolidate?

• A. 1922; consolidation of the RSFSR and other soviet republics into the USSR
• B. 1917; the Russian Empire's transformation
• C. 1929; the creation of a federation of states
• D. 1945; postwar alliance structure

Answer: (A)

The main idea being tested is when the Soviet Union became a single federal state and what it brought together. The USSR was formally created in 1922, when representatives from the Russian Soviet Federative Socialist Republic and other Soviet republics signed the treaty to unite into the Union of Soviet Socialist Republics. This move consolidated the RSFSR with neighboring Soviet republics—like the Ukrainian SSR, Byelorussian SSR, and Transcaucasian SFSR—into one central state centered in Moscow, sharing certain powers (such as defense and foreign policy) while preserving the individual republics within the union. The date in 1922 marks the official establishment, not the later postwar or industrial milestones. The other dates reflect revolutions or events unrelated to the creation of the USSR.
