The bimonthly newspaper Za vozvrashchenie na Rodinu ("Return to the Motherland") was published between 1955-1960 in East Berlin, primarily aimed at Russian emigrants in the West. Against the background of the Cold War, it was established under the watchful eye of the KGB and published by the Soviet Repatriation Committee, serving as an important anti-Western propaganda outlet for the USSR. The main objective was to create a favorable image of the Soviet Union and to criticize émigré organizations in the post-war period. During its publication, the newspaper was not available to the public on a subscription basis, therefore it has become a rare information resource.
