However this may be, and whether his aid were besought or not, the Emperor had other matters to attend to, and left the Britons to themselves. He abandoned, in like manner, Narbonnese Gaul and Armorica. This last province, which was less corrupted by the influence of Roman civilization, displayed greater energy than the other two. It took measures for its own defence, by forming a kind of federative league against maritime invasions. Spain, which was also deserted, endeavoured to maintain itself in the same manner against attacks of the same nature; but acted with little vigour, and met with small success. In Great Britain, as well as in Gaul, the Roman government had destroyed the energy of their native independence, and had substituted in its stead nothing but its own artificial and despotic organization. When the Romans withdrew, the children of the Gauls, inhabiting Roman cities, were incapable alike of self-government or self-defence, and fell an easy prey to a few bands of foreign marauders, who had come in search of booty and adventures. Let us briefly glance at the progress of their conquests. Invasions Of The Germans. No determinate epoch can be accurately assigned to the first invasions of the Germans. In all ages, their hordes were wont to descend from their forest-fastnesses into countries less wild and more cultivated than their own. Among their early irruptions, the first regarding which we have any precise historical information is that of the Cimbri and Teutones, who, three hundred thousand in number, ravaged Italy during the time of Marius. [Footnote 6] [Footnote 6: In B.C. 113-101. Marius finally defeated the Teutones at Aix, in the year 102; and the Cimbri, near Vercelli, in the year 101.] From the age of Augustus to the fifth century, these invasions continued, but were very unequal in importance. Bands of men, unable to find means of subsistence in their own country, entered the imperial territory, and pillaged as they went; their fate was decided by the event of a battle; they were dispersed or annihilated by a defeat, or, if victorious, they took possession of some district which pleased them. Frequently, also, they settled in the country by the consent of the emperors. In the third century, Probus received three or four thousand Franks into Auvergne. {27} Foundation Of Barbarian Kingdoms.
