Pope Adrian I (; died 25 December 795) was the bishop of Rome and ruler of the Papal States from 1 February 772 to his death. He was the son of Theodore, a Roman nobleman. Adrian and his predecessors had to contend with periodic attempts by the Lombards to expand their holdings in Italy at the expense of the papacy. Not receiving any support from Constantinople, the popes looked for help to the Franks. Adrian's tenure saw the culmination of on-going territorial disputes between Charlemagne and his brother Carloman I. The Lombard king Desiderius supported the claims of Carloman's sons to their late father's land, and requested Pope Adrian crown Carloman's sons "Kings of the Franks". When the Pope failed to do so, Desiderius invaded Papal territory and seized the Duchy of the Pentapolis. Charlemagne besieged Pavia and took the Lombard crown for himself. He then restored the Pentapolis to the Papacy as well as some of the captured Lombard territory. Start of papacy Shortly after Adrian's accession in 772, the territory ruled by the papacy was invaded by Desiderius, king of the Lombards, and Adrian was compelled to seek the assistance of the Frankish king Charlemagne, who entered Italy with a large army. Charlemagne besieged Desiderius in his capital of Pavia. After taking the town, he banished the Lombard king to the Abbey of Corbie in France, and adopted the title "King of the Lombards" himself. The pope, whose expectations had been aroused, had to content himself with some additions to the Duchy of Rome, the Exarchate of Ravenna, and the Pentapolis in the Marches, which consisted of the "five cities" on the Adriatic coast from Rimini to Ancona with the coastal plain as far as the mountains. He celebrated the occasion by striking the earliest papal coin, and in a mark of the direction the mediaeval papacy was to take, no longer dated his documents by the Emperor in the east, but by the reign of Charles, king of the Franks. He recognized the authority of Pope Adrian I, and in return the pope gave Charlemagne the title of "Patrician of Rome". A mark of such newly settled conditions in the Duchy of Rome is the Domusculta Capracorum, the central Roman villa that Adrian assembled from a nucleus of his inherited estates and acquisitions from neighbors in the countryside north of Veii. The villa is documented in Liber
