DOCTORAL THESIS Ivana HERGLOVÁ --- KINGDOM OF BOHEMIA - NEIGHBOUR OF BAVARIA IN THE LATE MIDDLE AGES AND IN THE EARLY MODERN TIMES --- Abstract --- The thesis is dedicated to research in the field of Bavarian-Bohemian relations, mainly in the field of politics, in the 15th and early 16th century. Main interest is given to the contacts between the Kingdom of Bohemia and the four partial duchies into which Bavaria was subdivided in this period - (Lower) Bavaria-Straubing, Bavaria-Munich, Bavaria-Landshut and Bavaria-Ingolstadt. The work is divided into four large parts. The first goes on the Hussite Wars (1419-1434/36). The second part analyses Czech royal election of the year 1440 and the motives of the selected candidate, the duke Albrecht III of Bavaria-Munich, to finally decline the election. This chapter is followed by a summary of the political cooperation between Czech kings Ladislaus Posthumus (1453-1457) and George of Podiebrad (1458-1471) and the duke Louis/Ludwig IX of Bavaria-Landshut. The last chapter of the thesis describes the attempt of the Bavarian dukes (of the now reunited Duchy of Bavaria) William/Wilhelm IV and Louis/Ludwig X to become the kings of Bohemia as a part of their competition for hegemony in the middle European region with the house of Habsburg.
