did not yet encroach upon the civil power. She had the right of acquiring property, of holding councils, subject to the imperial authority, and of the free election of bishops. But only the first germs of ecclesiastical jurisdiction are to be traced. In virtue of the laws, the bishops were privileged arbitrators, and in the matter of public sins exercised a disciplinary jurisdiction over the clergy and the faithful. In the second half of the 4th century, monasteries appeared in Gaul. After the fall of the Western empire, there was left to the Gallo-Romans as an expression of its law, which was also theirs, a written legislation. It consisted of the imperial constitutions, contained in the Gregorian, Hermogenian and Theodosian codes (the two former being private compilations, and the third an official collection), and the writings of the five jurists (Gaius, Papinian, Paulus, Ulpian and Modestinus), to which Valentinian III. had in 426 given the force of law. _The Barbarian Invasion._--The invasions and settlements of the barbarians open a new period. Though there were robbery and violence in every case, the various barbarian kingdoms set up in Gaul were established under different conditions. In those of the Burgundians and Visigoths, the owners of the great estates, which had been the prevailing form of landed property in Roman Gaul, suffered partial dispossession, according to a system the rules regulating which can, in the case of the Burgundians, be traced almost exactly. It is doubtful whether a similar process took place in the case of the Frankish settlements, but their first conquests in the north and east seem to have led to the extermination or total expulsion of the Gallo-Roman population. It is impossible to say to what extent, in these various settlements, the system of collective property prevailing among the Germanic tribes was adopted. Another important difference was that, in embracing Christianity, some of the barbarians became Arians, as in the case of the Visigoths and Burgundians; others Catholic, as in the case of the Franks. This was probably the main cause of the absorption of the other kingdoms into the Frankish monarchy. In each case, however, the barbarian king appeared as wishing not to overthrow the Roman administration, but to profit by its continuation. The kings of the Visigoths and Burgundians were at first actually representatives of the Western empire, and Clovis himself was ready to accept from the emperor Anastasius the title of consul; but these were but empty forms, similar to the fictitious ties which long existed or still exist between China or Turkey and certain parts of their former empires, now separated from them for ever.
