The Kingdom of Bohemia at the end of the Middle Ages was a country in upheaval, for which the Hussite Revolution (1419-1436) stands in a defining way. In five thematic groups, the internationally known and renowned Czech mediavist František Šmahel sheds light on the manifold aspects that set central Europe in motion in the 25 essays from the past four decades, which have been brought together here and which have had a significant impact on research and which have been partially revised and updated in the annotation apparatus let. The topics range from the political position of the Bohemian countries to the changing power and social structures, the role of Tábor in Hussitism, the purgatorium sompniatum in the Hussite topography of the afterlife to the central role of the Four Prague Articles and questions of the visual Agitation during the study period.
