At the end of the 9th century, Hungarians arrived to central Europe and founded their kingdom. The first king was Stephen I of theArpad dynasty, which ruled the Kingdom of Hungary until 1301. Stephen I is credited with converting Hungarians to Christianity and for the first ecclesiastical organization, as well as for erecting the first cathedrals and monasteries. The length of reign of Arpad dynasty largely coincides with the period of Romanesque architecture and art in Europe and in the Hungarian Kingdom itself. Since the history of the dynasty is related to the development of architecture, a brief historical overview is presented at the beginning of the thesis, covering the period from the arrival of the Hungarians to the Carpathian basin until the extinction of the dynasty and the arrival of a new, dynasty of Anjou, to the Hungarian throne. The main part of the thesis systematically represents individual sacral buildings in the territory of the former Hungarian Kingdom, with an emphasis on royal endowments, but certain monuments are also included without which the image of Hungarian Romanesque architecture would not be complete, such as noble endowments. Monuments are classified by their function and a special emphasis is given to the possible provenance of influence, which is synthesized in the last chapter.
