by the blackness of the horizon. In fact, whilst in the Eastern Church the metaphysical ardour of the Greeks was spending itself in terrible combats in the oecumenical councils over the interpretation of the Nicene Creed, the clergy of Gaul, more simple and strict in their faith, abjured these theological logomachies; from the first they had preferred action to criticism and had taken no part in the great controversy on free-will raised by Pelagius. Another kind of warfare was about to absorb their whole attention; the barbarians were attacking the frontiers of the Empire on every side, and their advent once again modified Gallo-Roman civilization.
For centuries they had been silently massing themselves around ancient Europe, whether Iberian, Celtic or Roman. Many times already during that evening of a decadent civilization, their threatening presence had seemed like a dark cloud veiling the radiant sky of the peoples The barbarian invasion. established on the Mediterranean seaboard. The cruel lightning of the sword of Brennus had illumined the night, setting Rome or Delphi on fire. Sometimes the storm had burst over Gaul, and there had been need of a Marius to stem the torrent of Cimbri and Teutons, or of a Caesar to drive back the Helvetians into their mountains. On the morrow the western horizon would clear again, until some such disaster as that which befell Varus would come to mortify cruelly the pride of an Augustus. The Romans had soon abandoned hope of conquering Germany, with its fluctuating frontiers and nomadic inhabitants. For more than two centuries they had remained prudently entrenched behind the earthworks that extended from Cologne to Ratisbon (Regensburg); but the intestine feuds which prevailed among the barbarians and were fostered by Rome, the organization under bold and turbulent chiefs of the bands greedy for booty, the pressing forward on populations already settled of tribes in their rear; all this caused the Germanic invasion to filter by degrees across the frontier. It was the work of several generations and took various forms, by turns and simultaneously colonization and aggression; but from this time forward the pax romana was at an end. The emperors Probus, Constantine, Julian and Valentinian, themselves foreigners, were worn out with repulsing these repeated assaults, and the general enervation of society did the rest. The barbarians gradually became part of the Roman population; they permeated the army, until after Theodosius they recruited it exclusively; they permeated civilian society as colonists and agriculturists, till the command of the army and of important public duties was given over to a Stilicho or a Crocus. Thus Rome allowed the wolves to mingle with the dogs in watching over the flock, just at a time when the civil wars of the 4th century had denuded the Rhenish frontier of troops, whose numbers had already been diminished by Constantine. Then at the beginning of the 5th century, during a furious irruption of Germans fleeing before Huns, the limes was carried away (406–407); and for more than a hundred years the torrent of fugitives swept through the Empire, which retreated behind the Alps, there to breathe its last.
Whilst for ten years Alaric’s Goths and Stilicho’s Vandals were drenching Italy with blood, the Vandals and the Alani from the steppes of the Black Sea, dragging in their wake the reluctant German tribes who had been allies of Rome and who had already settled down to the cultivation of The Germans in Gaul. their lands, invaded the now abandoned Gaul, and having come as far as the Pyrenees, crossed over them. After the passing of this torrent the Visigoths, under their kings Ataulphus, Wallia and Theodoric, still dazzled by the splendours of this immense empire, established themselves like submissive vassals in Aquitaine, with Toulouse as their capital. About the same time the Burgundians settled even more peaceably in Rhenish Gaul, and, after 456, to the west of the Jura in the valleys of The Franks before Clovis. the Saône and the Rhône. The original Franks of Germany, already established in the Empire, and pressed upon by the same Huns who had already forced the Goths across the Danube, passed beyond the Rhine and occupied north-eastern Gaul; Ripuarians of the Rhine establishing themselves on the Sambre and the Meuse, and Salians in Belgium, as far as the great fortified highroad from Bavai to Cologne. Accepted as allies, and supported by Roman prestige and by the active authority of the general Aetius, all these barbarians rallied round him and the Romans of Gaul, and in 451 defeated the hordes of Attila, who had advanced as far as Orleans, at the great battle of the Catalaunian plains.
Thus at the end of the 5th century the Roman empire was nothing but a heap of ruins, and fidelity to the empire was now only maintained by the Catholic Church; she alone survived, as rich, as much honoured as ever, and more powerful, owing to the disappearance of the imperial The clergy and the barbarians. officials for whom she had found substitutes, and the decadence of the municipal bodies into whose inheritance she had entered. Owing to her the City of God gradually replaced the Roman imperial polity and preserved its civilization; while the Church allied herself more closely with the new kingdoms than she had ever done with the Empire. In the Gothic or Burgundian states of the period the bishops, after having for a time opposed the barbarian invaders, sought and obtained from their chief the support formerly received from the emperor. Apollinaris Sidonius paid court to Euric, since 476 the independent king of the Visigoths, against whom he had defended Auvergne; and Avitus, bishop of Vienne, was graciously received by Gundibald, king of the Burgundians. But these princes were Arians, i.e. foreigners among the Catholic population; the alliance sought for by the Church could not reach her from that source, and it was from the rude and pagan Franks that she gained the material support which she still lacked. The conversion of Clovis was a master-stroke; it was fortunate both for himself and for the Franks. Unity in faith brought about unity in law.
Clovis was king of the Sicambrians, one of the tribes of the Salian Franks. Having established themselves in the plains of Northern Gaul, but driven by the necessity of finding new land to cultivate, in the days of their king Childeric they had descended into the fertile valleys of the Clovis, the Frankish chief. Somme and the Oise. Clovis’s victory at Soissons over the last troops left in the service of Rome (486) extended their settlements as far as the Loire. By his conversion, which was due to his wife Clotilda and to Remigius, bishop of Reims, more than to the victory of Tolbiac over the Alamanni, Clovis made definitely sure of the Roman inhabitants and gave the Church an army (496). Thenceforward he devoted himself to the foundation of the Frankish monarchy by driving the exhausted and demoralized heretics out of Gaul, and by putting himself in the place of the now enfeebled emperor. In 500 he conquered Gundibald, king of the Burgundians, reduced him to a kind of vassalage, and forced him into reiterated promises of conversion to orthodoxy. In 507 he conquered and killed Alaric II., king of the Arian Visigoths, and drove the latter into Spain. Legend adorned his campaign in Aquitaine with miracles; the bishops were the declared allies of both him and his son Theuderich (Thierry) after his conquest of Auvergne. At Tours he received from the distant emperor at Constantinople the diploma and insignia of patricius and Roman consul, which legalized his military conquests by putting him in possession of civil powers. From this time forward a great historic transformation Clovis as a Roman officer. was effected in the eyes of the bishops and of the Gallo-Romans; the Frankish chief took the place of the ancient emperors. Instead of blaming him for the murder of the lesser kings of the Franks, his relatives, by which he had accomplished the union of the Frankish tribes, they saw in this the hand of God rewarding a faithful soldier and a converted pagan. He became their king, their new David, as the Christian emperors had formerly been; he built churches, endowed monasteries, protected St Vaast (Vedastus, d. 540), first bishop of Arras and Cambrai, who restored Christianity in northern Gaul. Like the emperors before him Clovis, too, reigned over the Church. Of his own authority he called together a council at Orleans in 511, the year of his death. He was already the grand distributor of ecclesiastical benefices, pending the time when his successors were to confirm the episcopal elections, and his power began to take
