The Chatti, although thus driven away from the Rhine, appear in the sequel as the most powerful among the tribes of inland Germany who came into contact with the Romans; the lead which, under Augustus and Tiberius, had been possessed by the Cherusci on the middle Weser, passed, amidst the constant feuds with these their southern cognate neighbours, over to the latter. All the wars between Romans and Germans, of which we have any knowledge from the time after the death of Arminius down to the time when the migrations of the peoples began at the end of the third century, were waged against the Chatti; as in the year 41 under Claudius by Galba, who became afterwards emperor; and in the year 50 under the same emperor by Publius Pomponius Secundus, celebrated as a poet. These were the usual border incursions, and the Chatti had taken a part, but only a secondary one, in the great Batavian war (p. 133). But in the campaign which the Emperor Domitian undertook in the year 83 the Romans were the aggressors; and this war led, not indeed to brilliant victories, but doubtless to a considerable and momentous pushing forward of the Roman frontier.[74] At that time the frontier-line was arranged, as we find it thenceforth drawn; and within that line, which in its most northern portion was not far removed from the Rhine, must have been included a great part of the Taunus and the region of the Main as far as above Friedberg. The Usipes, who, after their already-mentioned expulsion from the region of the Lippe, appear about the time of Vespasian in the neighbourhood of Mentz, and may have found new settlements to the east of the Mattiaci on the Kinzig or in the Fuldan district, were then annexed to the empire, and, at the same time with them, a number of smaller tribes thrown off by the Chatti. Thereupon, when in the year 88, under the governor Lucius Antonius Saturninus, the upper German army rose against Domitian, the war was on the point of renewal; the revolted troops made common cause with the Chatti;[75] and it was only the interruption of the communications, when the ice broke up on the Rhine, that made it possible for the regiments which had remained faithful to settle matters with the revolters before the dangerous contingent arrived. It is stated that the Roman rule extended from Mentz towards the interior 80 _leugae_, and thus even beyond Fulda;[76] and this account appears worthy of credit, if we take into consideration that the military frontier-line, which certainly seems not to have gone far above Friedberg, doubtless kept here also within the territorial boundary.
