BOJ O BABENBERSKÉ DEDIČSTVO A I. ČESKO-UHORSKÁ VOJNA 1252 – 1254

The study deals with the first Czech-Hungarian conflict over the Babenberg heritage in 1252 – 1254. The author states that this was preceded by several years of instability and fights for the Duchy of Austria and Styria. Outwards, this was originally the rivalry between the Emperor Frederick II. Hohenstaufen and the Papal Curia; however, none of their duchy candidates was able to fully succeed. Finally, thanks to the support of Austrian nobility, the heir to the Czech throne, Přemysl Ottokar, enters the ducal position, legitimized by his subsequent marriage to the heiress Margareta. This has encouraged the Hungarian King, Belo IV., whose claims lead to a war. In spite of the vast Hungarian predominance, this war ended by the distribution of the Babenberg heritage, with Austria remaining on the Czech side and a majority of Styria on the Hungarian.
