 In late June or early July 1152, the Frederick I granted Conrad the title of duke for his lands around the Kvarner Gulf, possibly as a reward for helping Frederick secure the throne after the king's death.He used the title "dux Meranus" to refer to his coastal territory, but Bishop Otto I of Freising, in his history of Frederick's reign, calls him "Duke of Dalmatia and Croatia".He was also sometimes called "Duke of Dachau", but he was still officially a count there.
