A fellow traveller (also fellow traveler) is a person who is intellectually sympathetic to the ideology of a political organization, and who co-operates in the organization's politics, without being a formal member.[1] In the early history of the Soviet Union, the Bolshevik revolutionary and Soviet statesman Anatoly Lunacharsky coined the term poputchik ('one who travels the same path'); it was later popularized by Leon Trotsky to identify the vacillating intellectual supporters of the Bolshevik government.[2] It was the political characterisation of the Russian intelligentsiya (writers, academics, and artists) who were philosophically sympathetic to the political, social, and economic goals of the Russian Revolution of 1917, but who did not join the Communist Party of the Soviet Union. The usage of the term poputchik disappeared from political discourse in the Soviet Union during the Stalinist era, but the Western world adopted the English term fellow traveller to identify people who sympathised with the Soviets and with Communism.[1]
In U.S. politics, during the 1930s, 1940s and 1950s, the term fellow traveler was primarily a pejorative applied to those on the political left, to suggest a person who was philosophically sympathetic to Communism, yet was not a formal, "card-carrying member" of the Communist Party USA. In political discourse, the term fellow traveler was applied to intellectuals, academics, and politicians who lent their names and prestige to Communist front organizations. In European politics, the equivalent terms for fellow traveller are: Compagnon de route and sympathisant in France; Weggenosse, Sympathisant (neutral) or Mitläufer (negative connotation) in Germany; and compagno di strada in Italy.[3]
