Duchy of Carinthia
Upon the death of Duke Henry II of Bavaria in 995, Otto received the Duchy of Carinthia and the March of Verona back. When Emperor Otto III had died in 1002, Otto of Worms and Henry IV of Bavaria were candidates for the election as King of the Romans; Otto withdrew and received the Duchy of Carinthia from the newly elected king Henry (then Henry II of Germany) in return. Nevertheless, he was forced to cede his Rhenish possessions to his long-time rival Bishop Burchard of Worms.
