A bloody war was instantly excited among the barbarians of Spain; and the contending princes are said to have addressed their letters, their ambassadors, and their hostages, to the throne of the Western emperor, exhorting him to remain a tranquil spectator of their contest, the event of which must be favourable to the Romans, by the mutual slaughter of their common enemies. The Spanish War was obstinately supported during three campaigns, with desperate valour and various success; and the martial achievements of Wallia diffused through the empire the superior renown of the Gothic hero. He exterminated the Silingi, who had irretrievably ruined the elegant plenty of the province of Bætica. He slew in battle the king of the Alani; and the remains of those Scythian wanderers who escaped from the field, instead of choosing a new leader, humbly sought a refuge under the standard of the Vandals, with whom they were ever afterwards confounded. The Vandals themselves, and the Suevi, yielded to the efforts of the invincible Goths. The promiscuous multitude of barbarians, whose retreat had been intercepted, were driven into the mountains of Gallæcia; where they still continued, in a narrow compass, and on a barren soil, to exercise their domestic and implacable hostilities. In the pride of victory, Wallia was faithful to his engagements; he restored his Spanish conquests to the obedience of Honorius; and the tyranny of the imperial officers soon reduced an oppressed people to regret the time of their barbarian servitude.
His victorious Goths, forty-three years after they had passed the Danube, were established, according to the faith of treaties, in the possession of the second Aquitania, a maritime province between the Garumna (Garonne) and the Liger (Loire), under the jurisdiction of Bordeaux. The Gothic limits were enlarged by the additional gift of some neighbouring dioceses; and the successors of Alaric fixed their royal residence at Tolosa, which included five populous quarters, or cities, within the spacious circuit of its walls. About the same time, in the last years of the reign of Honorius, the Goths, the Burgundiones, and the Franks obtained a permanent seat and dominion in the provinces of Gaul. The liberal grant of the usurper Jovinus to his Burgundian allies was confirmed by the lawful emperor; the lands of the First or Upper Germany were ceded to those formidable barbarians; and they gradually occupied, either by conquest or treaty, the two provinces which still retain, with the titles of Duchy and of County, the national appellation of Burgundy.
The Franks, the valiant and faithful allies of the Roman Republic, were soon tempted to imitate the invaders whom they had so bravely resisted. Augusta Trevirorum, the capital of Gaul, was pillaged by their lawless bands; and the humble colony which they so long maintained in the district of Toxandria, in Brabant, insensibly multiplied along the banks of the Meuse and Scheldt, till their independent power filled the whole extent of the Second or Lower Germany.
The ruin of the opulent provinces of Gaul may be dated from the establishment of these barbarians, whose alliance was dangerous and oppressive, and who were capriciously impelled, by interest or passion, to violate the public peace. The odious name of conquerors was softened into the mild and friendly appellation of the “guests” of the Romans; and the barbarians of Gaul, more especially the Goths, repeatedly declared that they were bound to the people by the ties of hospitality, and to the emperor by the duty of allegiance and military service.
[409-423 A.D.]
Whilst Italy was ravaged by the Goths, and a succession of feeble tyrants oppressed the provinces beyond the Alps, the British island separated itself from the body of the Roman Empire. The regular forces which guarded that remote province had been gradually withdrawn; and Britain was abandoned, without defence, to the Saxon pirates and the savages of Ireland and Caledonia. The Britons, reduced to this extremity, no longer relied on the tardy and doubtful aid of a declining monarchy. They assembled in arms, repelled the invaders, and rejoiced in the important discovery of their own strength. Afflicted by similar calamities, and actuated by the same spirit, the Armorican provinces (a name which comprehended the maritime countries of Gaul, between the Seine and the Loire) resolved to imitate the example of the neighbouring island. They expelled the Roman magistrates, who acted under the authority of the usurper Constantine; and a free government was established among a people who had so long been subject to the arbitrary will of a master. The independence of Britain and Armorica was soon confirmed by Honorius himself, the lawful emperor of the West; and the letters, by which he committed to the new states the care of their own safety, might be interpreted as an absolute and perpetual abdication of the exercise and rights of sovereignty (409).
