The result of all these invasions was a progressive barbarization of Italy, which was not altogether unfortunate, because fraught with some renewal of strength. The Teutons brought their customs; and at least one Teuton people, the Lombards, maintained them masterfully. The Ostrogoth, Theodoric, had preserved the Italian municipal organization, and had drawn his code for all from Roman sources. But the first Lombard Code, that of King Rothari, promulgated about 643, ignored Roman law, and apparently the very existence of Romans. Though written in barbarous Latin, it is Lombard through and through. So, to a scarcely less degree, is the Code of King Liutprand, promulgated about 725.[136] Even then the Lombards looked upon themselves as distinct from the “Romans.” Their laws were still those of the Lombards, yet of Lombards settling down to urban life. Within Lombard territories the “Romans” were subjects. In Liutprand’s Code they seem to be referred to under the name of _aldii_ and _aldiae_, male and female persons, who were not slaves and yet not free. Instead of surrendering one-third of the land, the Romans were obliged to furnish one-third of its produce. Hence their Lombard masters were interested in keeping them fixed to the soil, perhaps in a state of serfdom. Little is known as to the intermarriage of the stocks, or when the Lombards adopted a Latin speech.[137] It is difficult, either in Italy or elsewhere, to follow the changes and reciprocal working of Roman and Teutonic institutions through these obscure centuries. They wrought upon each other universally, and became what neither had been before. The Roman State was there no longer; where the names of its officials survived they stood for altered functions. The Roman law prevailed within the dominions of the eastern Empire and the popes. Everywhere the crass barbarian law and the pure Roman institution was passing away, or changing into something new. In Italy another pregnant change was taking place, the passing of the functions of government to the bishops of Rome. Its stages are marked by the names of great men upon whose shoulders fell the authority no longer held by a remote ruler. Leo the Great heads the embassy which turns back the Hun; a century and a half afterwards Gregory the Great leads the opposition to the Lombards, still somewhat unkempt savages. Thereafter each succeeding pope, in fact the papacy by necessity of its position and its aspirations, opposes the Lombards when they have ceased to be either savage or Arian. It is an absent supporter that the papacy desires, and not a rival close at hand: Charlemagne, not Desiderius.
