The Complete History of USSR Borders (1922-1991)

Explore the complete territorial evolution of the Soviet Union, from the collapse of the Russian Empire in 1917 to the dissolution of the USSR in 1991. This video explains how the Soviet state expanded, stabilized, and eventually fragmented, showing every major border change across Eastern Europe, the Caucasus, Central Asia, and the Baltic region. Through a clear chronological map timeline, you’ll see how Ukraine, Belarus, the Baltic states, the Caucasus republics, and Central Asia became part of the USSR, how World War II reshaped Soviet borders, and how fifteen independent countries emerged from one of the largest states in world history. If you enjoy border evolution, historical maps, and clear documentary-style storytelling, this video breaks down the rise and fall of the Soviet Union in a simple and visual way.
