US declaration of war on Germany
On 2 April 1917, United States President Woodrow Wilson asked a special joint session of the US Congress to declare war on the German Empire. Congress obliged by declaring war on the 6th, with the resolution passing 82 to 6 in the Senate and 373 to 50 in the House.
On October 25 (Old Style), Bolshevik Red Guards, led by Leon Trotsky, mounted an armed insurrection in Petrograd, capital of the Russian Republic, capturing several government buildings. The following day, they seized the Winter Palace, the seat of Alexander Kerensky's Provisional Government. The Bolsheviks declared a new government, the Council of People's Commissars, with Vladimir Lenin as its head. Simultaneously and over the following days, other Bolshevik uprisings took place in towns and cities across Russia.
