After the October 1912 Duma elections, where six Bolsheviks and six Mensheviks were elected, Stalin wrote articles calling for reconciliation between the two Marxist factions, for which Lenin criticised him. In late 1912, Stalin twice crossed into the Austro-Hungarian Empire to visit Lenin in Kraków, eventually bowing to Lenin's opposition to reunification with the Mensheviks. In January 1913, Stalin travelled to Vienna, where he researched the 'national question' of how the Bolsheviks should deal with the Russian Empire's national and ethnic minorities. Lenin, who encouraged Stalin to write an article on the subject, wanted to attract those groups to the Bolshevik cause by offering them the right of secession from the Russian state, but also hoped they would remain part of a future Bolshevik-governed Russia.
