The February Revolution began on February 23 (March 8 in the Gregorian calendar) and lasted until March 3, 1917. It was marked by mass protests and strikes in Petrograd (now St. Petersburg), the capital city of Russia, which ultimately led to the fall of the Tsarist government. The February Revolution was largely a spontaneous movement led by workers, soldiers, and peasants who were dissatisfied with the oppressive Tsarist regime.
