Editing Pope Adrian I (section)

====Background====
Upon the death of [[Pepin the Short]] in 768, his kingdom was left to his sons [[Charlemagne]] and [[Carloman I]]. Relations between the brothers were said to be strained. In 770 Tassilo III, Duke of Bavaria married a Lombard princess, [[Liutperga]], daughter of King Desiderius, to confirm the traditional alliance between Lombardy and Bavaria. That same year, Charlemagne concluded a treaty with Duke Tassilo, and married Liutperga's sister, [[Desiderata of the Lombards|Desiderata]], to surround Carloman with his own allies. Less than a year later, Charlemagne repudiated Desiderata and married [[Hildegard (queen)|Hildegard]], the daughter of Count [[Gerold of Kraichgau]] and his wife Emma, daughter, in turn, of [[Duke of Alemannia|Duke]] [[Hnabi|Nebe (Hnabi)]] of Alemannia.<ref>Reinhard Barth: ''Karl der Große'', Munich 2000, pp. 97–98.</ref> Hildegard's father had extensive possessions in the territory under Carloman's dominion. This marriage was advantageous to Charlemagne because it allowed him to strengthen his position east of the Rhine and also bind the Alemannian nobility to his side.<ref>Matthias Becher: ''Karl der Große'', München 1999, p. 108.</ref> With Desiderata's return to her father's court at Pavia, Desiderius was grievously insulted, and appears to have made an alliance with Carloman against Charlemagne and the Papacy, which looked to the Franks for protection against Lombard incursions into Papal territory.<ref name=McKitterick>McKitterick, Rosamond, ''The Frankish Kingdoms under the Carolingians''</ref>
