Editing Józef Piłsudski (section)

===Russian Revolution of 1905===
During the [[Russian Revolution of 1905]], Piłsudski played a leading role in events in [[Congress Poland]]. In early 1905 he ordered the PPS to launch a general strike there; it involved some 400,000 workers and lasted two months until it was broken by the Russian authorities.{{r|Zamo87_330}} In June 1905, Piłsudski sent paramilitary aid to an uprising in Łódź, later called [[Łódź insurrection (1905)|June Days]]. In Łódź, armed clashes broke out between Piłsudski's paramilitaries and gunmen loyal to Dmowski and his [[National Democracy (Poland)|National Democrats]].{{r|Zamo87_330}} On 22 December 1905, Piłsudski called for all Polish workers to rise up; the call went largely unheeded.{{r|Zamo87_330}}

Piłsudski instructed the PPS to boycott the elections to the [[First Duma]].{{r|Zamo87_330}} The decision, and his resolve to try to win Polish independence through revolution, caused tensions within the PPS, and in November 1906, the party fractured over Piłsudski's leadership.{{r|Zamo87_332}} His faction came to be called the "Old Faction" or "[[Polish Socialist Party – Revolutionary Faction|Revolutionary Faction]]" ("''Starzy''" or "''Frakcja Rewolucyjna''"), while their opponents were known as the "Young Faction", "Moderate Faction" or "[[Polish Socialist Party – Left|Left]]" ("''Młodzi''", "''Frakcja Umiarkowana''", "''Lewica''"). The "Young" sympathized with the [[Social Democracy of the Kingdom of Poland and Lithuania|Social Democrats of the Kingdom of Poland and Lithuania]], and believed priority should be given to co-operation with Russian revolutionaries in toppling the Russian Empire and creating a socialist [[utopia]] to facilitate negotiations for independence.{{r|PWN}} Piłsudski and his supporters in the Revolutionary Faction continued to plot a revolution against Tsarist Russia to secure Polish independence.{{r|PolandGov}} By 1909, his faction was the majority in the PPS, and Piłsudski remained an important PPS leader until the outbreak of the First World War.{{r|Urbank97_131}}
