Iskra (Russian:И́скра, IPA: [ˈiskrə], Spark) was a political newspaper of Russian socialist emigrants established as the official organ of the Russian Social Democratic Labour Party (RSDLP). Initially, it was managed by Vladimir Lenin, moving as he moved. The first edition was published in Leipzig, Germany, on December 1, 1900. Other editions were published in Munich (1900–1902) and Geneva from 1903. When Lenin was in London (1902–1903) the newspaper was edited from a small office at 37a Clerkenwell Green, EC1, with Henry Quelch arranging the necessary printworks.
