Baldus and Giangaleazzo Visconti's Feudal Rights

Giangaleazzo Visconti claimed a ducal title for himself and argued that all cities and lordships formerly subject to the Visconti vicariate were now subject to him as their feudal lord, based on the privilege Giangaleazzo received from Emperor Wenceslaus.  The privilege raised several legal problems.  It encroached upon the rights of imperial vassals in Lombardy and broke longstanding diplomatic ties between the emperor and local authorities.  Some German princes claimed that the emperor did not have the authority to grant such a privilege because it injured the imperial patrimony.
