Tampere conference of 1905
The first conference of the Russian Social Democratic Labour Party (RSDLP) took place in Tampere (Tammerfors), Grand Duchy of Finland, in December 1905. Held between the 1905 London and 1906 Stockholm party congresses at the Tampere Workers' Hall, the conference was an unofficial meeting of the Bolshevik faction of the party. It is particularly remembered for playing host to the first meeting of Vladimir Lenin and Joseph Stalin. The conference resolved to forgo participation in the new State Duma, as did most of the far left parties. They later reversed this decision in 1907.
The Tampere conference was conducted in secrecy, and little record remains of its proceedings. The only known documents that remain are the printed record of the resolutions reached at the meeting, and Lenin's report on its results. The exact timeframe of the conference is also unclear. Finnish sources suggest that it was held on 25–30 December, whilst according to Russian historian G. Kramolnikov, who wrote about the conference in the 1930s, it was opened earlier, with the first sessions held on 23 December.
