• January 5: The Constituent Assembly opens with an SR majority; Chernov is elected chairman. After several hours Lenin decrees the Assembly dissolved.
• January 12: 3rd Congress of Soviets accepts The Declaration of the Rights of the Peoples of Russia and creates the new constitution; Russia is declared a Soviet Republic and a federation is to be formed with other soviet states; the previous ruling classes are barred from holding any power. 'All power' is given to workers and soldiers.
• January 19: The Polish Legion declares war on the Bolshevik government.
February
• February 1/14: The Gregorian calendar is introduced to Russia, changing February 1st to February 14th and bringing the nation in synch with Europe.
• February 23: The 'Workers' and Peasants' Red Army' is officially founded; massive mobilisation follows to counter anti-Bolshevik forces.
March
• March 3: The Treaty of Brest-Litovsk is signed between Russia and the Central Powers, ending WW1 in the East; Russia concedes a massive amount of land, people and resources.
• March 6-8: The Bolshevik party changes its name from Russian Social Democratic Party (Bolsheviks) to Russsian Communist Party (Bolsheviks).
• March 9: Foreign intervention in the revolution begins as British troops land in Murmansk.
• March 11: The capital is moved from Petrograd to Moscow, partly because of German forces in Finland.
• March 15: The 4th Congress of Soviets agrees to the Treaty of Brest-Litovsk, but the Left SR's leave the Sovnarkom in protest; the highest organ of government is now entirely Bolshevik.
The process of establishing Bolshevik power, and thus the success of the October Revolution, continued over the next few years as a civil war raged across Russia. The Bolsheviks won and the Communist regime was securely established, but that's the subject for another timeline (The Russian Civil War).
