It is also from Tacitus that we glean what were the names and descriptions of those tribes who occupied the territory adjacent to the Rhine. The basin of the river between Strassburg and Mainz was inhabited by the Tribacci, Nemetes, and Vangiones, further south by the Matiacci near Wiesbaden, and the Ubii in the district of Cologne. Further north lay the Sugambri, and the delta of the river in the Low Countries was the seat of the brave Batavii, from whom came the bulk of the legions by means of which Agricola obtained a footing in far Caledonia. Before the Roman invasion of their territories these tribes were constantly engaged in internecine warfare, a condition of affairs not to be marvelled at when we learn that at their tribal councils the warrior regarded as an inspired speaker was he who was most powerfully affected by the potations in which all habitually indulged to an extent which seemed to the cultured Roman as bestial in the last degree. The constant bearing of arms, added to their frequent addiction to powerful liquors, also seemed to render the Germanic warriors quarrelsome to excess, and to provoke intertribal strife.
The Romans in the Rhine Country
Caesar is the first Roman writer to give us any historical data concerning the peoples who inhabited the basin of the Rhine. He conquered the tribes on the left bank, and was followed a generation or so later by Augustus, who established numerous fortified posts on the river. But the Romans never succeeded in obtaining a firm occupancy of the right bank. Their chief object in colonizing the Rhine territory was to form an effective barrier between themselves and the restless barbarian tribes of the Teutonic North, the constant menace of whose invasion lay as a canker at the heart of rich and fruitful Italy. With the terror of a barbarian inroad ever before their eyes, the cohorts of the Imperial City constructed a formidable vallum, or earthen wall, from the vicinity of Linz to Regensburg, on the Danube, a distance of three hundred and fifty miles, for the purpose of raising a barrier against the advance of the warlike men of the North. They further planted a colony of veterans in the Black Forest neighbourhood in order that invasion might be resisted from that side. But as the Empire began to exhibit signs of decadence the barbarians were quick to recognize the symptoms of weakness in those who barred their advance to the wealthy South, the objective of their dreams, hurled themselves against the boundary, now rendered feeble by reason of the withdrawal of its most experienced defenders, and, despite a stern resistance, flooded the rich valleys of the Rhine, swamped the colonies on the left bank which had imbibed Roman civilization, and made all wholly Teutonic.
The Rebellion of the Barbarians
This was, however, a process of years, and by no means a speedy conquest. The closing years of Augustus’ reign were clouded by a general rising of the Rhine peoples. Quintilius Varus, an officer who had been entrusted with the government of the provinces beyond the Rhine, proved totally unequal to curbing the bolder spirits among the Germans, who under their chief, Arminius, boldly challenged the forces of this short-sighted officer. Arminius belonged to the Cherusci. He had served with the German horsemen in the Rhenish armies, and was conversant with the Latin language. Observing that half, at least, of the Roman forces were on leave, he incited the tribes of Lower Saxony to revolt. The weak Varus, who had underestimated the influence of Arminius, attempted to quell the rising, but without success, and the bank of the river was the scene of a wholesale slaughter. Varus, completely losing his nerve, attempted to separate the cavalry from the infantry and endeavoured to escape with three squadrons of the former; but the Germans surrounded them, and after a hand-to-hand struggle of three days the Roman army was annihilated. The news of this disaster prompted the aged Emperor to dispatch his son Tiberius to suppress what appeared to be a general rising of the North. The Rhenish tribes, however, were too wary to meet the powerful force now sent against them in the open field, and during the remainder of the year Tiberius, left in peace, occupied himself in strengthening the Rhine fortifications.
He was soon after recalled to Rome to assume the purple on the death of Augustus. Germanicus, who had taken command of the legions on the Rhine, became conscious of discontent among the soldiers, who threatened to carry him into Rome and thrust him into the seat of empire. But he soothed the passions of his soldiers by gifts and promises. A road was opened from the Rhine into the German hinterland, and Germanicus led his army into the heart of a country of which he knew but little to avenge the disasters of the Varian legions. The forest folk eluded the invading host, which now sought to return to headquarters; but ere they had completed the journey they were assailed and suffered a severe reverse.
Numerous revolts occurred among the Gaulish legions in the service of the Roman Empire in Germany. But the stubborn and trained resistance of the Romans no less than the inexperience of the Gauls led to a cessation of hostilities. The secret of Roman power in Rhenish territory lay in the circumstance that the two great elements of German nationality, the nobility and the priesthood, were becoming Romanized. But a rude culture was beginning to blossom, and a desire arose among the barbarians for unity. They wished to band themselves into a nation.
The Franks and Goths
The most dangerous enemies of Rome during the reigns of Valerian and Gallienus were the Franks, the Alemanni, and the Goths, whose action finally decided the conquest of the Rhenish provinces of Rome. The name Frank, or Freedman, was given to a confederacy formed in A.D. 240 by the old inhabitants of the Lower Rhine and the Weser. It consisted of the Chauci, the Cherusci, and the Chatti, and of several other tribes of greater or less renown. The Romans foresaw the power of this formidable union and, by the presence of the Emperor himself and his son, endeavoured to stem the invasion, which threatened their suzerainty. The Franks, fond of liberty and imbued with a passion for conquest, crossed the Rhine, in spite of its strong fortifications, and carried their devastations to the foot of the Pyrenees. For twelve years Gallienus attempted to stem the torrent thus freed.
The Alemanni, who belonged to the Upper Rhine, between the Main and the Danube, were composed of many tribes, the most important of which was the celebrated Suevi. This people, who had now become a permanent nation, threatened the Empire with an invasion which was checked with difficulty after they had fought their way to the gates of Rome itself. In A.D. 271 Aurelian completely subdued the Rhenish peoples, numbers of whom were dragged in his triumph through the streets of Rome; but after his brief reign the old condition of things reasserted itself, until Probus, who assumed the purple in 276, restored peace and order by the construction of a massive wall between the Rhine and the Danube over two hundred miles in length. The barbarians were driven beyond the river, which had hitherto served as a boundary-line, even past the Elbe and the Neckar. Finally, however, the internecine strife in the Imperial City forced the Romans to return thence, and Rhineland was abandoned to the will of its semi-barbarian inhabitants.
