November 7 marks the 90th anniversary of the Russian Revolution.  Under the Julian Calendar, which was in use by Russia at the time of the Revolution, the date was October 25, 1917, hence the term "October Revolution" is still used to refer to this watershed event.

The Provisional Government has been deposed. State power has passed into the hands of the organ of the Petrograd Soviet of Workers' and Soldiers' Deputies--the Revolutionary Military Committee, which heads the Petrograd proletariat and the garrison.

The cause for which the people have fought, namely, the immediate offer of a democratic peace, the abolition of landed proprietorship, workers'control over production, and the establishment of Soviet power—this cause has been secured.

Long live the revolution of workers, soldiers and peasants!
