Апрельские тезисы
Vladimir Lenin, exiled in neutral Switzerland, arrived in Petrograd from Zürich on 16 April O.S (29 April N.S). He immediately began to undermine the provisional government, issuing his April Theses the next month. These theses were in favor of "Revolutionary defeatism", which argues that the real enemy is those who send the proletariat into war, as opposed to the "imperialist war" (whose "link to Capital" must be demonstrated to the masses) and the "social-chauvinists" (such as Georgi Plekhanov, the grandfather of Russian socialism), who supported the war. The theses were read by Lenin to a meeting of only Bolsheviks and again to a meeting of Bolsheviks and Mensheviks, both being extreme leftist parties, and was also published. He believed that the most effective way to overthrow the government was to be a minority party and to give no support to the Provisional Government. Lenin also tried to take control of the Bolshevik movement and attempted to win proletariat support by the use of slogans such as "Peace, bread and land", "End the war without annexations or indemnities", "All power to the Soviet" and "All land to those who work it".
