facing invasions from the north by the Danes and from the east by the Slavs and Hungarians, all available resources were required north of the Alps. Conrad believed that a client state relationship with Italy would be in Germany's best interest. He offered a peace treaty in which Berengar II would remain King of Italy on the condition that he recognized Otto as his overlord. Berengar II agreed and the pair traveled north to meet with Otto to seal the agreement. Conrad's treaty was met with disdain by Adelaide and Henry.

Her father Rudolf II of Burgundy was briefly king of Italy prior to being deposed and she herself had briefly been queen of Italy until her husband Lothair II of Italy's death. Berengar II imprisoned her when she refused to marry his son, Adalbert of Italy. Henry had other reasons to disapprove of the peace treaty.

Conrad and Henry were already not on good terms, and the proposed treaty drove the two dukes further apart. Adelaide and Henry conspired together to persuade Otto to reject Conrad's treaty. Conrad and Berengar II arrived at Magdeburg to meet Otto, but had to wait three days before an audience was granted. This was a humiliating offense for the man Otto had named his regent. Though Adelaide and Henry urged the treaty's immediate rejection, Otto referred the issue to an Imperial Diet for further debate.

In return, Otto granted Berengar II Italy as his fiefdom and restored the title "King of Italy" to him.

Otto reorganized this area into the March of Verona and put it under Henry's control as reward for his loyalty. The Duchy of Bavaria therefore grew to become the most powerful domain in Germany. Relations with the Catholic Church Beginning in the late 940s, Otto rearranged interior policies by utilizing the
