Which faction of the Marxist Russian Social Democratic Labour Party did Nikolai Krivoruchko join?
Bolsheviks The Bolsheviks, originally also Bolshevists or Bolsheviki (Russian: большевики, большевик (singular) ; ] ; derived from большинство "bol'shinstvo", "majority", literally meaning "one of the majority") were a faction of the Marxist Russian Social Democratic Labour Party (RSDLP) which split apart from the Menshevik faction at the Second Party Congress in 1903. The RSDLP was a revolutionary socialist political party formed in 1898 in Minsk in Belarus to unite the various revolutionary organisations of the Russian Empire into one party.
Independent Social Democratic Party of Germany The Independent Social Democratic Party of Germany (German: "Unabhängige Sozialdemokratische Partei Deutschlands" , USPD) was a short-lived political party in Germany during the German Empire and the Weimar Republic. The organization was established in 1917 as the result of a split of left wing members of the Social Democratic Party of Germany (SPD). The organization attempted to chart a centrist course between electorally oriented revisionism on the one hand and bolshevism on the other. The organization was terminated in 1931 through merger with the Socialist Workers' Party of Germany (SAPD).
