The Russian Revolution of 1917 was the greatest event in modern history. Between February and October, Russia passed from the overthrow of the Tsar, through a short episode of bourgeois rule, to the conquest of power by the Bolshevik Party and the establishment of the first workers state. To mark the centenary, the WSWS is publishing a weekly feature, This Week in the Russian Revolution, which provides a kaleidoscopic view of the Russian Revolution and the global events of 1917, an epochal year in world history.
The chronology uses the Gregorian calendar—the same calendar in common use today and in most of the Western world in 1917. In Russia at the time, the Julian calendar (Old Style or O.S.) was still in use, which was 13 days behind the Gregorian. This WSWS feature will include the Julian dates for events that took place within Russia, by placing them in parentheses after the modern date.
