History
During the Russian Civil War between Communists and counterrevolutionaries. The renound early cinema pioneer Dziga Vertov helped establish and run a film-car on Mikhail Kalinin's agit-train. He had equipment to shoot, develop, edit, and project film. The trains went to battlefronts on agitation-propaganda missions intended primarily to bolster the morale of the troops; they were also intended to stir up revolutionary fervor of the masses.
