 Not being able to trust the traditional structures of support for the Lombard monarchy, he sought support among the gasindii, the gentry bound to the king by treaties of protection, and especially among the Romans, the non-Lombard subjects.The adoption of ancient customs, along with public pro-Latin attitudes—he married a Roman woman, Tassia, and with Roman rite, and adopted the title of "princeps" instead of the traditional "rex Langobardorum"—increasingly alienated the Lombard base, which forced him to adopt a diametrically opposed policy, with a sudden attack on the cities of the Pentapolis.The pope, however, convinced him to abandon the siege of Perugia.
