The Historians' History of the World 06 [The Early Roman Empire]

Probus (M. Aurelius Probus), 276-282 A.D.

[276-279 A.D.]

On the death of Tacitus his brother Florianus claimed the empire as if fallen to him by inheritance, and the legions yielded him their obedience; but the army of the East obliged their general, Probus, to assume the purple, and a civil war commenced. The constitution of the European troops soon, however, began to give way under the heat of the sun of Asia; sickness spread among them, desertions became numerous, and when at Tarsus in Cilicia the army of Probus came to give them battle, they averted the contest by proclaiming Probus, and putting their emperor to death after a reign of less than three months.

Probus was another of those Illyrians who, born in a humble station, attained the empire by their merit, and honoured it by their virtues. He entered the army young, and speedily became distinguished for his courage and his probity. His merit did not escape the discerning eye of Valerian, who made him a tribune, though under the usual age; gave him the command of a body of auxiliary troops, and recommended him strongly to Gallienus, by whom and by the succeeding emperors he was greatly esteemed, and trusted with important commands. Aurelian rated him very highly, and is even thought to have destined him for his successor.

After the death of Florianus, Probus wrote to the senate, apologising for having accepted the empire from the hands of the soldiery, but assuring them that he would submit himself to their pleasure. A decree was unanimously passed investing him with all the imperial titles and powers. In return Probus continued to the senate the right of hearing appeals, appointing magistrates, and of giving force to his edicts by their decrees.

Tacitus had punished severely some of those concerned in the murder of Aurelian; Probus sought out and punished the remainder, but with less rigour. He exhibited no enmity toward those who had supported Florianus.

The Germans had taken advantage of the interregnum which succeeded the death of Aurelian to make a formidable irruption into Gaul, where they made themselves masters of not less than seventy cities, and were in possession of nearly the whole of the country. Probus, however, as soon as his affairs permitted (277), entered Gaul at the head of a numerous and well-appointed army. He gave the Germans several defeats, and forced them to repass the Rhine with a loss, it is said, of four hundred thousand men.[50] He pursued them over that river, and nine of their kings were obliged to come in person to sue for peace. The terms which the emperor imposed were the restoration of all their booty, the annual delivery of a large quantity of corn and cattle, and sixteen thousand men to recruit the Roman armies. These Probus distributed in parties of fifty and sixty throughout the legions, for it was his wise maxim that the aid derived from the barbarians should be felt, not seen. He also placed colonies of the Germans and other tribes in Britain, and some of the other provinces. He had further, it is said, conceived the idea of making the conquered Germans renounce the use of arms and trust for their defence to those of the Romans; but on considering the number of troops it would require he gave it up, contenting himself with making them retire behind the Nicer (Neckar) and Albis (Elbe), with building forts and towns in the country between these rivers and the Rhine, and running a wall two hundred miles in length from the Rhine to the Danube as a defence to Italy and the provinces against the Alamanni.
