2nd Congress of the Russian Social Democratic Labour Party
The 2nd Congress of the Russian Social Democratic Labour Party was held during July 30–August 23 (July 17–August 10, O.S.) 1903, starting in Brussels, Belgium (until August 6) and ending in London. Probably as a result of diplomatic pressure from the Russian Embassy, Belgian police had forced the delegates to leave the country. The congress finalized the creation of the Marxist party in Russia proclaimed at the 1st Congress of the RSDLP.
