The February Revolution of 1917 was a pivotal event in Russian history that resulted in the abdication of Tsar Nicholas II and the end of the Romanov dynasty. It was triggered by a combination of long-term issues such as widespread discontent with autocratic rule, economic hardship, and military failures during World War I. Short-term triggers included protests over food shortages, worker strikes, and the collapse of order in Petrograd. The revolution was characterized by mass demonstrations, mutinies in the army, and the eventual resignation of the Tsar, leading to the establishment of a provisional government.

Historian A argues that the revolution was primarily caused by long-standing economic and political issues, while Historian B emphasizes the immediate protests and military mutinies as the main triggers.
