List of kings of the Lombards in the context of "Cathedral of Monza"

The Carolingian Empire (800–887) was a Frankish-dominated empire in Western and Central Europe during the Early Middle Ages. It was ruled by the Carolingian dynasty, which had ruled as kings of the Franks since 751 and as kings of the Lombards in Italy from 774. In 800 Pope Leo III crowned King Charlemagne as Roman emperor in return for political protection, disregarding the universalist claims of the weakened Byzantine Empire. The Carolingian Empire is sometimes considered the first phase in the history of the Holy Roman Empire.

After a civil war from 840 to 843 following the death of Emperor Louis the Pious, the empire was divided into autonomous kingdoms, with one king still recognised as emperor but with little authority outside his own kingdom. The unity of the empire and the hereditary right of the Carolingians continued to be acknowledged. In 884 Charles the Fat reunited all the Carolingian kingdoms for the last time, but he was deposed by the Frankish nobility in 887 and died in 888, and the empire immediately fractured. With the only remaining legitimate male of the dynasty a child, the nobility elected regional kings from outside the dynasty or, in the case of the eastern kingdom, an illegitimate Carolingian. The illegitimate line continued to rule in the east until 911, while in the western kingdom the legitimate Carolingian dynasty was restored in 898 and ruled until 987 with an interruption from 922 to 936.

The Bavarian dynasty refers to those kings of the Lombards who were descended from Garibald I of Bavaria, a member of the Agilolfing dynasty and duke of Bavaria. They came to rule the Lombards through Garibald's daughter, Theodelinda, who married King Authari in 588. The Bavarians (Italian: Bavaresi) were effectively a branch of the Agilolfings, and can be divided into two lines: the female line, descended through Theodelinda, and the male line, through Garibald's son Gundoald.

Of the female line, only Adaloald—Theodelinda's son by her second husband, Agilulf—reigned. Her son-in-law Arioald, husband of her daughter Gundeberga, also became king.

Charlemagne (/ˈʃɑːrləmeɪn/ SHAR-lə-mayn; 2 April 748 – 28 January 814) was King of the Franks from 768, King of the Lombards from 774, and Emperor of what is now known as the Carolingian Empire from 800. He united most of Western and Central Europe and was the first recognised emperor to rule from the west after the fall of the Western Roman Empire approximately three centuries earlier. Charlemagne's reign was marked by political and social changes that had lasting influence on Europe throughout the Middle Ages.

A member of the Frankish Carolingian dynasty, Charlemagne was the eldest son of Pepin the Short and Bertrada of Laon. With his brother Carloman I, he became king of the Franks in 768 following Pepin's death and became the sole ruler three years later. Charlemagne continued his father's policy of protecting the papacy and became its chief defender, removing the Lombards from power in northern Italy in 774. His reign saw a period of expansion that led to the conquests of Bavaria, Saxony, and northern Spain, as well as other campaigns that led Charlemagne to extend his rule over a large part of Europe. Charlemagne spread Christianity to his new conquests (often by force), as seen at the Massacre of Verden against the Saxons. He also sent envoys and initiated diplomatic contact with Harun al-Rashid, the Abbasid caliph in the 790s, due to their mutual interest in Iberian affairs.

The Donation of Pepin, or Donation of Pippin, was the transfer of Frankish territory in central Italy to Pope Stephen II made by Pepin the Short, King of the Franks, in 756. Credited with "effectively establishing the temporal authority of the papacy," the Donation took place amid the Byzantine Empire's decline in Italy and marked both "an important moment in the papal–Carolingian alliance" and an "important step" in the formation of the Papal States. With the fall of the imperial capital in Italy, Ravenna, to Aistulf, King of the Lombards in 751, "any semblance of imperial protection for Rome" had evaporated and the pope, who had technically been a Byzantine subject to this point, turned to Pepin for assistance. Pepin invaded Italy and, following an initial victory in 755, he decisively "defeated Aistulf and imposed a peace on him" in 756.

Pepin had promised Italian lands to Stephen II at a meeting in Quierzy, France in April 754. While this earlier promise is "often identified as the Donation," it may have been only verbal and "does not exist in written form." Papal accounts of the 754 promise state that Pepin "granted the pope the exarchate, including Ravenna, and the Roman duchy." In 756, the "Confession of St. Peter," a document listing the cities involved in the Donation, was "placed on the altar of Old St. Peter’s Basilica in Rome" along with "keys of the cities and territories in central Italy." The Confession document was created "following Pippin’s second invasion of Italy to assist the pope." After his initial invasion in 755, Pepin concluded the First Peace of Pavia, but Aistulf "refused to abide by" this agreement and attacked Rome. Pepin then defeated Aistulf again, imposing "heavy penalties" with the Second Peace of Pavia in 756.

Aistulf (also Ahistulf, Haistulfus, Astolf etc.; Latin: Aistulfus, Italian: Astolfo; died December 756) was the Duke of Friuli from 744, King of the Lombards from 749, and Duke of Spoleto from 751. His reign was characterized by ruthless and ambitious efforts to conquer Roman territory to the extent that in the Liber Pontificalis, he is described as a "shameless" Lombard given to "pernicious savagery" and cruelty.

Wacho (also Waccho; probably from Waldchis) was king of the Lombards before they entered Italy from an unknown date (perhaps c. 510) until his death in 539. His father was Unichis. Wacho usurped the throne by assassinating (or having assassinated) his uncle, King Tato (again, probably around 510). Tato's son Ildchis fought with him and fled to the Gepids where he died. Wacho had good relations with the Franks.

Wacho married three times. His first marriage was to Raicunda, daughter of Bisinus, King of the Thuringi. His second marriage was to Austrigusa, a Gepid possibly named after her maternal descent from Ostrogothic rulers. Austrigusa was the mother of two daughters: Wisigarda (who married Theudebert I of Austrasia) and Waldrada (who married firstly Theudebald of Austrasia, secondly Chlothar I, King of the Franks, and thirdly Garibald I of Bavaria). Wacho's third marriage was to Silinga, a Heruli, mother of Waltari. According to some historians (Josef Poulík), he was buried on Žuráň hill, however, modern historians are not certain about it.
