Вацлав I
In 1253 Ottokar had settled himself in Styria. He appointed Henry as governor of Styria and returned to Bohemia. Bela IV then attacked Bohemia, and in the war that followed, Ottokar's father, King Wenceslaus I of Bohemia, was killed. The war was ended by the Treaty of Buda of 1254, in which Ottokar ceded Styria to Bela.
