Abstract
The study presents popular conspiracy theories spread within the Czech and Slovak language milieu. Along with the growth in the number of internet portals disseminating this type of texts, their reflection in public opinion is also visible in the way almost every major foreign policy issue or domestic case is commented upon in public internet discussions.
The authors seek to identify the narrative and rhetorical sources of conspiracism in these countries since the rise of modern nationalism in the 19th century, focusing on the events accompanying the creation of the common state of the Slovaks and Czechs, the period of the Second World War, the rule of the Communist regime, the events related to the fall of the Iron Curtain and the "Velvet Revolution" in 1989 up to the present. The paper focuses attention on group-shared images of the enemies and on mutual interactions between the interpretations of local events and global conspiracy theories, as well as updates or later reinterpretations of older conspiracy motifs.
