The goal of this MA thesis is to present the establishing process of the Angevin royal authority in medieval Croatia and Dalmatia. Starting with the assumption that the successful continuation of the political and social structures encompassed by the modern anachronism „medieval state“ depends on the interaction of the central government and the leading groups of society, the conceptual basis of the thesis aims to simultaneously include both the actions and the efforts of the center and the response of the local elite of the considered areas. In an effort to set the basic parameters for the later examination of the existence of continuity elements, the thesis provides a brief overview of the development of political and social structures of Croatia and Dalmatia from the moment of incorporation into the Kingdom of Hungary to the twilight of the Arpad dynasty. Examining the course of the establishment of royal power, through the analysis of the principal opponents of the restoration of ruling authority, the fundamental contradictions that influenced the formation of a separate approach of Angevin rulers to each of the associated areas are underlined. Furthermore, an overview of the process of consolidating the new order provides an outline of the political infrastructure on which the Angevin rule rested, showing the characteristics of the central government's interaction with the remaining local political factors during their integration into government structures. Finally, relying on the theoretical models of modern historiography, the thesis aims to distance itself from the hithero perpetuated interpretations of the restoration of royal authority in medieval Croatia and Dalmatia and propose an alternative explanation of the strategies, actions, and desired goals of relevant historical actors.
