The Russian Revolution refers to a series of revolutionary actions that took place between March 8, 1917 and Nov. 8, 1917. It started with the February Revolution and ended with the October, or Bolshevik, Revolution. Both are named according to the Julian calendar, which is 13 days behind the Gregorian.
On March 8, peasants and women laborers led riots and strikes throughout Petrograd, or St. Petersburg. The February Revolution lasted for several days and resulted in the abdication of Czar Nicholas II and the formation of a dual government created by the former imperial parliament, called Duma, and the Petrograd Soviet, or council. This created tension that erupted in numerous protests and violent outbursts for months. Vladimir Lenin and the Bolsheviks orchestrated the October Revolution on Nov. 6 and 7 through occupation of government offices before seizing full governmental control on Nov. 8.
