Followers of the Narodnik tradition established the Socialist-Revolutionary Party or Esers in 1901, advocating the distribution of land among those who actually worked it—the peasants. A third radical group founded the Russian Social Democratic Labour Party or RSDLP in 1898; this party was the primary exponent of Marxism in Russia. Gathering their support from the radical intellectuals and the urban working class, they advocated complete social, economic and political revolution.

There was an instituted mandatory conscription of the rural peasantry into the Red Army. Opposition of rural Russians to Red Army conscription units was overcome by taking hostages and shooting them when necessary in order to force compliance. Former Tsarist officers were utilized as "military specialists" (voenspetsy), taking their families hostage in order to ensure loyalty. At the start of the war, three-fourths of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers.

Document 15: Russian Revolution: The February Revolution (March 1917) was a revolution focused around Petrograd (now Saint Petersburg), the capital of Russia at that time. In the chaos, members of the Imperial parliament (the Duma) assumed control of the country, forming the Russian Provisional Government which was heavily dominated by the interests of large capitalists and the noble aristocracy. The army leadership felt they did not have the means to suppress the revolution, resulting in Nicholas's abdication. The soviets, which were dominated by soldiers and the urban industrial working class, initially permitted the Provisional Government to rule, but insisted on a prerogative to influence the government and control various militias.
