Ioseb Besarionis Dze Jugashvili (1878–1953), better known by his Anglicized party name Joseph Stalin, was an ethnic Georgian intellectual and Marxist revolutionary affiliated with the Bolshevik wing of the Russian Social Democratic Labour Party (RSDLP). Jugashvili regarded Bolshevik leader Vladimir Lenin (1870–1924) as a role model and intellectual beacon, and the young activist was sometimes jokingly called "Lenin's left foot" by his Georgian comrades. Jugashvili did not just admire the exiled Lenin from afar through correspondence but had even met him personally, with the pair jointly attending the 1907 Congress of the RSDLP held in London as part of a 92-member Bolshevik delegation.
