 After initial military successes, much of the Italian clergy and some noble families swore allegiance to Henry II, including Archbishop Arnulf II.Joining Henry II in Bergamo, Arnulf II crowned him as King of Italy ("Rex Italiae") on May 14, 1004 in Pavia.Unlike his predecessors, after gaining the Kingdom of Italy Henry II wore two crowns, one for Germany and one for Italy, instead of a common crown representing both realms.
