The wanderings of the Bavarian dukes had given another powerful neighbour, Charles Martel, the ruler of the Franks, the opportunity of interfering with them. There are proofs that friendly intercourse existed between the Franks and the Lombards, even before the latter migrated to Italy. Theudebert I, one of the few descendants of Clovis who has left an honourable name in history, was wedded to Wisigarda, a daughter of King Wacho, whose second daughter, Walderada, was the first wife of Theudebald, the illegitimate son of the successor of Theudebert. All friendly relations between these two peoples ceased with Alboin, who, before he married the notorious Rosamund, took to wife a daughter of Clotair I, named either Clotosuinda or Flutswinda, and after his time we find them opposed and hostile to one another. At first during the years 568, 571, 572, 574, and 575, there were only insignificant battles, brought about by the incursions of the Lombard tribes who were not yet settled in the Frankish territory. More serious, and not exactly conducive to fame or success for the Franks, were the wars which Childebert II, in pursuance of an agreement made by him with the East Roman emperor, himself conducted against Authari down to the year 590. It was only under Agilulf that peace was actually secured in 591.
In 605, in connection with the marriage of King Adalwald with a daughter of Theudebert II, a bond of “everlasting peace between the Franks and Lombards” was sworn to. We are also told by Paulus that King Grimwald almost completely annihilated a Frankish host, which had passed from Provence into upper Italy, but no exact date is furnished. It was only when under the strong rule of the first Carlovingians on the one hand and of Liutprand on the other, when order was to some extent restored in both kingdoms, that the two rulers once more approached one another with a view to the discussion of a foreign policy. In 725 Charles Martel undertook his first campaign, in order to put the Bavarians in mind of their long-forgotten dependence on the Franks. There are no chronicles which tell us whether or not Liutprand then came into communication with his great contemporary. But it is certain that a good understanding existed between them in the years which followed, a friendship which only grew closer with time. This is proved chiefly by the fact that Charles Martel, in his thirties, sent his youthful son Pepin (born 714 or 715) to the Lombard king that the king might cut off his hair “according to the custom.” This Liutprand did, assuming by this act the place of second father to the young man, afterwards sending him home, enriched by many presents. According to two later chroniclers Charles had then already concluded an alliance with Liutprand, an assertion which the historian has rather deduced from later occurrences, than based upon any exact knowledge of the actual facts.
When the Saracens again invaded Gaul, and had pushed on into Provence, Charles sent envoys bearing presents to Liutprand, and asked him for assistance, which was granted. The report of a Lombard army in the neighbourhood was sufficient to induce the “unbelievers,” who had reached the valley of Susa, to retreat, and to the abandonment of Arles (Arelate).
LIUTPRAND AND THE ITALIAN POWERS
[731-744 A.D.]
The expeditions to Bavaria and France are the only ones Liutprand undertook outside of Italy. Even within the peninsula his predecessors had not left him very much to do. The change of rulers repeatedly enforced in the second half of the seventh and the beginning of the eighth century was, of course, anything but advantageous to the aggrandisement of the Lombard royal house. The leading forces in the country, the dukes, whose power dated from the earliest monarchical times in Italy, made what use they could of the internecine discord to assert their own authority.
At the extreme point of independence of the crown stood the Beneventine dukes, who from time immemorial had maintained a unique position in the south, being indeed recognised by constitutional law as almost independent of the kingly power. They traced back their origin to royal blood, to Duke Gisulf of Friuli, a brother of Alboin.
In 731 Liutprand found an opportunity to interfere in Beneventine affairs. He came in person to Benevento, and took away with him his grand-nephew who was not of age, whilst in his place he installed his nephew Gregory, leaving him peacefully established before he returned.
