This milestone marked the outbreak and beginning of this historic period, which spanned 1917.

The October Revolution, also known as the Great October Socialist Revolution, October coup, Bolshevik coup, or Bolshevik Revolution, was the second of two revolutions in Russia in 1917. It was led by Vladimir Lenin's Bolsheviks as part of the broader Russian Revolution of 1917–1923. It began through an insurrection in Petrograd on 7 November 1917 [O.S. 25 October]. It was the precipitating event of the Russian Civil War. The initial stage of the October Revolution, which involved the assault on Petrograd, occurred largely without any casualties.
