In the years following the October Revolution of 1917, the Soviet government sponsored the Russian film industry with the purpose of making propaganda films. The development of Russian cinema in the 1920s by such filmmakers as Dziga Vertov and Sergei Eisenstein saw considerable progress in the use of the motion picture as a propaganda tool, yet it also served to develop the art of moviemaking. Eisenstein's films, in particular 1925's "The Battleship Potemkin", are seen as masterworks of the cinema, even as they glorify Eisenstein's Communist ideals. In depicting the 1905 Russian Revolution "Potemkin" sought to create a new history for Russia, one led and triumphed over by the formerly oppressed masses. Eisenstein was heavily influenced by the ideology of the 1917 Bolshevik revolution, which results in it providing better insight into the mindset of the later revolution than that which it depicted. Its dual purpose beyond forging a national Russian identity was to bring its revolutionary Communist message to the West. Its influence was feared in Germany to the extent that the government banned the film when it was released in the late 1920s. Another of Eisenstein's films, 1927's "", depicted the Bolshevik perspective on the October Revolution, culminating in the storming of the Winter Palace which provided Soviet viewers with the victory that the workers and peasants lacked in "Battleship Potemkin", ending with Lenin (as played by an unknown worker) declaring that the government is overthrown. Because no documentary material existed of the storming of the palace, Eistenstein's re-creation of the event has become the source material for historians and filmmakers, giving it further legitimacy as the accepted historical record, which illustrates its success as a propaganda film.
