Munich, London, and Geneva: 1900–1905

After his exile, Lenin settled in Pskov in early 1900. There, he began raising funds for a newspaper, Iskra (Spark), a new organ of the Russian Marxist party, now calling itself the Russian Social Democratic Labour Party (RSDLP). In July 1900, Lenin left Russia for Western Europe; in Switzerland he met other Russian Marxists, and at a Corsier conference they agreed to launch the paper from Munich, where Lenin relocated in September. Containing contributions from prominent European Marxists, Iskra was smuggled into Russia, becoming the country's most successful underground publication since 1850s. He first adopted the pseudonym Lenin in December 1901, possibly based on the Siberian River Lena; he often used the fuller pseudonym of N. Lenin, and while the N did not stand for anything, a popular misconception later arose that it represented Nikolai. Under this pseudonym, in 1902 he published his most influential publication to date, the pamphlet What Is to Be Done?, which outlined his thoughts on the need for a vanguard party to lead the proletariat to revolution. He also used the name " Jacob Richter " to get a reader's ticket at the British Museum Reading Room.
