31. On the same day his body was prepared for burial and borne to the church of the Virgin Mary, which he had founded, in the midst of the lamentation of all his people, and there laid to rest. Over his tomb was erected an arch, covered with gold, and having his image and this inscription on it: "Under this tomb lies the body of Karl, the great and orthodox emperor, who greatly increased the kingdom of the Franks and ruled gloriously for forty-seven years. He died when over seventy years of age, in the year of our Lord 814, the 7th indiction, on the fifth of the Kalends of February." {42} In the late Merovingian period the outlying parts of the kingdom had become practically independent under native rulers, called dukes. One of the first things undertaken by the rulers of the new line was the reduction of these great provinces to subjection as a necessary step in the restoration of the central authority. Much was accomplished in this direction by the mayors, Pippin the Younger (688-714) and Karl Martel (714-741), who attacked the Frisians, the dukes of Aquitaine, Bavaria, and Alamannia. But the work had to be done over and over, and indeed was never permanently accomplished. In Aquitaine Pippin the Short, king from 751 to 768, had several conflicts with the dukes of Aquitaine, Hunold and his son Waifer. This is the struggle which Karl brought to an end as here related. {43} Pippin had begun his war upon the Lombards for the purpose of freeing the papal domains from their attacks. The Lombards had conceived the ambitious plan of possessing all Italy, and under their kings Liutprand, Aistulf, and Desiderius had begun to carry it out by attacking the exarchate of Ravenna and the lands held by the pope. Pippin had forced Aistulf to give up his conquests (chiefly the exarchate) and had given that territory to the pope (see no. 45). Karl was called into Italy to defend the pope against a new attack by Desiderius, and put a definite end to this danger by conquering the Lombard kingdom and adding it to his own rule. This is a further stage in the connection between the popes and the emperor, between Germany and Italy.
