Meanwhile, as the population sank into exhaustion, it yielded less and less revenue, the police deteriorated, and the guards became unable to protect the frontier. In 376, the Goths, hard pressed by the Huns, came to the Danube and implored to be taken as subjects by the emperor. After mature deliberation the Council of Valens granted the prayer, and some five hundred thousand Germans were cantoned in Moesia. The intention of the government was to scatter this multitude through the provinces as _coloni,_ or to draft them into the legions; but the detachment detailed to handle them was too feeble, the Goths mutinied, cut the guard to pieces, and having ravaged Thrace for two years, defeated and killed Valens at Hadrianople. In another generation the disorganization of the Roman army had become complete, and Alaric gave it its death-blow in his campaign of 410. Alaric was not a Gothic king, but a barbarian deserter, who, in 392, was in the service of Theodosius. Subsequently he sometimes held imperial commands, and sometimes led bands of marauders on his own account, but was always in difficulty about his pay. Finally, in the revolution in which Stilicho was murdered, a corps of auxiliaries mutinied and chose him their general. Alleging that his arrears were unpaid, Alaric accepted the command, and with this army sacked Rome. During the campaign the attitude of the Christians was more interesting than the strategy of the soldiers. Alaric was a robber, leading mutineers, and yet the orthodox historians did not condemn him. They did not condemn him because the sacred class instinctively loved the barbarians whom they could overawe, whereas they could make little impression on the materialistic intellect of the old centralized society. Under the empire the priests, like all other individuals, had to obey the power which paid the police; and as long as a revenue could be drawn from the provinces, the Christian hierarchy were subordinate to the monied bureaucracy who had the means to coerce them. Yet only very slowly, as the empire disintegrated, did the theocratic idea take shape. As late as the ninth century the pope prostrated himself before Charlemagne, and did homage as to a Roman emperor. [Footnote: Perz, _Annales Lauressenses_, I, 188.] Saint Benedict founded Monte Cassino in 529, but centuries elapsed before the Benedictine order rose to power. The early convents were isolated and feeble, and much at the mercy of the laity, who invaded and debauched them. Abbots, like bishops, were often soldiers, who lived within the walls with their wives and children, their hawks, their hounds, and their men-at-arms; and it has been said that, in all France, Corbie and Fleury alone kept always something of their early discipline.
