This master presents the deposition of kings in medieval Europe by the nobility. The focus of the master is on the ideological elements that the nobility used to limit the royal power. Namely, in theory, the medieval nobility was presented as a "community of the kingdom" that protected the kingdom from tyrant rulers, and in the name of the welfare of the kingdom, it did not even hesitate to depose the king. However, in practice, the nobility used the limitation of the royal power and its eventual overthrow for the realization of their own political and economic interests. The nobility expressed their interests in the form of coronation conspiracies and charters that the rulers had to respect in order to be crowned, which means that the royal power was of an elective and contractual nature. In case of royal disobedience of the charters, the nobility had the right to organize an armed rebellion against the kings. The issue of the deposition of kings in medieval Europe is explained by using the examples of the reign of the English kings John Lackland, the Hungarian-Croatian rulers Mary of Anjou, Sigismund of Luxemburg and Matthias Corvinus, and the reign of the Holy Roman Emperor Wenceslaus IV.
