Iskra
Iskra (Russian: Искра, lit. 'Spark') was a clandestine Marxist newspaper founded in December 1900 by Vladimir Lenin and fellow Russian revolutionaries including Georgy Plekhanov, Julius Martov, Vera Zasulich, and Pavel Axelrod, serving as the central organ for disseminating revolutionary theory and organizing the fragmented Russian Social Democratic Labour Party (RSDLP).[1][2] Published initially in Leipzig and subsequently in Munich and other European cities to evade tsarist censorship, Iskra aimed to ignite proletarian consciousness by critiquing "economism"—a tendency among Russian Marxists to limit agitation to workplace grievances rather than broader political struggle—and advocating for a vanguard party of professional revolutionaries.[3][1] The newspaper's editorial board, dominated by émigré intellectuals, coordinated a network of agents inside Russia to distribute issues and build party infrastructure, achieving 46 issues by 1903 and playing a pivotal role in convening the RSDLP's Second Congress.[4][5] At that 1903 congress in London and Brussels, disputes over party membership criteria—Lenin's push for a disciplined core versus Martov's looser definition—split the Iskra-ists into Bolshevik and Menshevik factions, with Lenin seizing control of the paper briefly before its cessation as the unified organ.[6] Iskra was revived sporadically from 1905 to 1906 under Menshevik influence but never regained its formative authority, though its emphasis on centralized leadership profoundly shaped Bolshevik organizational principles leading to the 1917 Revolution.[7][8]
