Markéta Novotná Abstract - The Feudo-vassal System on Royal Estates in Early Modern Bohemia The study is devoted to the topic of feudo-vassal relations in early modern Bohemia presented on a sample of specific royal and chamber domains at the castle Karlštejn. The first part of the thesis describes how the feudo-vassal tenures were treated in Czech and European historical studies, using impulses from the philosophy and sociology. The others chapters are dedicated to the main object of this analysis - to the Karlštejn vassal system - a group of small-sized estates connected to castle Karlštejn through feudo-vassal bonds. The second chapter of the thesis deals with the problem of historical consciousness, where the castle Karlštejn is imagined as the site of "the national memory", which strongly effected the interpretation of the Karlštejn vassal system. The third (main) part of the thesis presents the factual analysis of the Karlštejn vassal system from the last third of sixteenth century to the turn of the seventies and the eighties of the next century. At the end of the study the analysis of four chosen vassal estates is added. Key words: Karlštejn, historiography, vassals, feudal system, domain, chamber, lower nobility
