King of Italy
When Arduin of Ivrea, in lieu of Henry of Saxony (the future Henry II, Holy Roman Emperor), dynastic successor of Otto III, was elected King of Italy and crowned in Pavia, the traditional site of crowning of the Lombard and Italian kings, Arnulf II stood on the side of Henry. After the defeat of Arduin of Ivrea, Arnulf II went to Pavia to crown Henry of Saxony, on 15 May 1004, new King of Italy.
