General Overview: In 1917 Russia went through two revolutions: February 24 - 29 and October 24 - 25. The first revolution overthrew the tsarist government and replaced it with a Provisional Government of Duma members (mostly members of the Cadet party), who allowed a Contact Commission of the Petrograd Soviet to advise the government. Protests and strikes against the new government quickly grew as Russia's involvement in World War I lingered on, and the Provisional Government responded by establishing a Coalition Government with the Executive Committee of the Petrograd Soviet. This Dual Power however, created a confused bureaucratic quagmire, leading the government to inaction on urgent issues such as the widespread famine and slaughter on the front. Such crisis resulted in opportunities for some to seize autocratic power, as Kerensky and General Kornilov attempted.
On October 24 - 25 the Bolshevik party led Russian workers and peasants to revolution, under the slogan of: "All power to the Soviets". On October 25 - 26, the Second All-Russia Congress of Soviets met and created the Soviet Government through the elections of a new Council of People's Commissars and Central Executive Committee. The new government resolved to begin construction on a Socialist society, but soon encountered extreme obstacles: while attempting to come to peace with all warring nations, only Germany agreed to peace (see the Treaty of Brest-Litovsk). When World War I ended, fresh off the battlefields of the Western Front, the Entente powers (US, UK, France, Japan, etc) invaded Russia from all directions, assisted by tsarist generals and provisional government politicians. A four year Civil War ravaged the country with catastrophic famine and casualties, forcing the government to adopt War Communism in order to survive. By the end of the war, a devastated Russia began to slowly rebuild with such programs as the NEP.
