In the political and cultural landscape shaped by the devastation of World War II, Soviet authorities embarked on an effort that may sound counterintuitive against the prevailing image of Stalinism: a large-scale campaign for scientific and political literacy that was launched in 1947 and lasted through 1991. This campaign created an immense infrastructure that permeated postwar Soviet society with popular narratives of science, medicine, history, and politics, among other fields of knowledge. Within this campaign, political literacy was frequently taught under the formal banners of “scientific communism” and “Marxism-Leninism.” Yet the actual vernacular of political literacy that emerged from this propaganda system shifted away from orthodox Marxist explanations rooted in class struggle and economic determinism toward more engaging narrative forms. Conspiratorial interpretations with their language of secret operations, global plots, and political vigilance as a virtue proved particularly persuasive for narrativizing international politics. By the time the Soviet Union collapsed in December 1991, several generations of its citizens had been systematically trained to privilege hidden agency and secret causality to explain political reality.
