イシュトヴァーン5世
In 1270 the new King Stephen V of Hungary visited Bolesław the Chaste in Kraków, where they signed an eternal peace. In the same year, Stephen V renewed the war against Bohemia for the Babenberg inheritance, which ended in the defeat of Hungary. In 1271 Bolesław, with the help of Rurikid princes, organized an expedition to the Duchy of Wrocław, because Henry the White was an ally of Bohemia.
