Adrian I (720-795)
Adrian I (pope, 772-795) was born in 720 as a member of a noble Roman family. From the beginning of his pontificate he was forced by difficulties with the Lombards to invoke the aid of Charlemagne. This led to Charlemagne's Frankish invasion of Italy (774), overthrowing the Lombard kingdom in the north and incorporating it under his control. Charlemagne also renewed the alliance between the papacy and the Franks, confirming and augmenting the Donation of Pepin (providing a legal basis for the creation of the Papal States).
Charlemagne let it be seen that he considered Rome a Frankish city, that he regarded the pope as his subject and that he believed that the Church should be Germanised. Adrian had to be content with the independence — somewhat more than nominal — which Charlemagne allowed.
After 780, Adrian dates his letters, not according to the reign of the Eastern emperor, but according to those of his own pontificate, and he began to coin money in his own name.
