In 1900, Axelrod, Plekhanov, and Zasulich joined with the younger revolutionary Marxists Julius Martov, Vladimir Lenin, and Alexander Potresov to form the editorial board of "Iskra", a Marxist newspaper, from 1900 to 1903. When "Iskra" supporters split at the Second Congress of the Russian Social Democratic Labor Party in 1903, Axelrod sided with the Menshevik faction.
