the entire party adopted an internationalist position with the onset of World War I in 1914. The Warsaw Committee of the SDKPiL called a conference of all revolutionary factions for August 2 at which both the Warsaw Committee and Central Committee were joined by the PPS Lewica (Left) and the Bund. The conference issued an unequivocal denunciation of imperialist war and called for the workers to take state power. Despite this attempts to coordinate the different parties came to nothing. But as the war continued both social democratic factions joined the Zimmerwald movement with the Warsaw Committee becoming particularly close to the Bolsheviks. The growing clarification of right and left internationally would enable the two factions of the party to reunify at a congress held on November 4, 1916, a new Central Committee was elected and the party pledged support to the Zimmerwald movement. End of the party The February Revolution of 1917 in Russia saw the Russian Provisional Government issue a manifesto on March 30 recognising Poland's right to an autonomous status, while the Petrograd Soviet recognised Poland's right to self-determination. Those Polish Social Democrats working with the Bolsheviks (such as Dzierżyński and Julian Leszczyński (Leński)) vehemently dissented. The end of the war in 1918 saw SDKPiL members spread throughout revolutionary Europe and playing leading roles everywhere they went. Thus Luxemburg and Jogiches stood at the head of the newly founded Communist Party of Germany (KPD, founded 1918), while Dzierżyński, Radek and Yakov Hanecki all participated fully in the October Revolution in Russia and took up posts in the nascent Soviet government. The history of the SDKPiL drew to a close when its influence and that of its members had never been as widespread. In 1918, many of the party's members would take part in the movement of workers' councils in Poland, before eventually merging with the PPS Lewica to form the Communist Workers Party of Poland.
