The study is continuation of three papers already published in the Vojenská história magazine, which had analysed the causes, development and consequences of the Czech-Hungarian war in 1254 – 1256, the war in 1260 and the third war in 1270 – 1271. The current study deals with the situation following the death of the Hungarian King Stephan V., when the Hungarians provoked a new Hungarian-Czech war, again resulting in the Czech attacks against the Hungarian territory, revealing the military dominance of the Czech forces lead by Přemysl Otakar II. The paper continues dealing with the topic of war over the Babenberg heritage, where this Central European framework concentrates on a detailed analysis of the sources in terms of participation of the Hungarian nobility as well as the course of military events against the background of the relations between the Austrian, Czech and Hungarian countries.
