Russian Revolution (1917)

The Russian Revolution of 1917, a two-part upheaval encompassing the February democratic uprising and the October Bolshevik coup, led to the creation of the world's first communist state. This new regime, which eventually formed the Soviet Union, spanned 11 time zones and exerted considerable influence on communist movements across the globe for 70 years. The Soviet Union's rise profoundly reshaped the 20th-century geopolitical landscape, particularly through the Cold War, where it stood as a rival superpower to the United States. Its collapse in 1991 marked a significant turning point in international relations, ending decades of ideological conflict and altering the global order.
