Between 1248 and 1250, he operated as the imperial governor of Styria and Carniola, from 1250 onwards also in Austria. In 1252, he was forced to take certain possessions in Lienz as fiefs from the Philipp, Archbishop of Salzburg, in the Treaty of Lieserhofen and to give his sons to him as hostages.
