Maroboduus, the King of the Marcomanni, settled his followers in the neighbourhood of Vienna, having formed the idea of creating a great military power in Germany; it was the first conception of a German Empire, for many tribes were to be united in the confederacy by which the aggressions of Rome were to be stopped, and the tide of invasion possibly turned in the opposite direction. This man, a Suevian by birth, had been a hostage, and was brought up under the care of Augustus at Rome; in this case, as in several others, the policy of educating a native prince, so that he might bring his people under Roman civilization, proved to be of doubtful advantage. Maroboduus applied the lessons which he learned at Rome to resisting the extension of the Empire. He got together a force of 70,000 foot and 4,000 cavalry, drilled them carefully in the Roman fashion, and fixed upon Bohemia as the suitable centre of his Empire. He did not attack the Romans, that was not his first object; he wished to civilize Germany and create a counterpoise to Rome. Tiberius saw that this could not be permitted; the proposed German Empire was too near the turbulent Pannonian region for safety; it was necessary to nip the nascent civilization of Central Europe in the bud. In order finally to break the power of Maroboduus, Tiberius decided to carry out another of those vast combined operations in which he had already twice succeeded. He sent Sentius Saturninus with one army to march from the Rhine through the Hercynian forest to the Danube, while he himself brought up another army from Cis-Alpine Gaul through the Julian Alps. The operation was so admirably planned and its details so well considered, that the two armies found themselves each within five days of their meeting point, when a fresh outbreak of Pannonia and Dalmatia threatened Tiberius in the rear, and compelled him to take his army back to another scene of war. Though this great operation failed in one way, it seems to have succeeded in another; it effectually cowed Maroboduus, who did not intervene, as might have been anticipated, in the Pannonian troubles, while it shook the confidence of the Germans in their self-appointed Emperor; we find him at a later time a fugitive living under the protection of Rome.
