This important measure was not carried into execution till about six years after the association of Maximian, and that interval of time had not been destitute of memorable incidents. But we have preferred, for the sake of perspicuity, first to describe the more perfect form of Diocletian's government, and afterwards to relate the actions of his reign, following rather the natural order of the events, than the dates of a very doubtful chronology.

The first exploit of Maximian, though it is mentioned in a few words by our imperfect writers, deserves, from its singularity, to be recorded in a history of human manners. He suppressed the peasants of Gaul, who, under the appellation of Bagaudæ, had risen in a general insurrection; very similar to those which in the fourteenth century successively afflicted both France and England. It should seem that very many of those institutions, referred by an easy solution to the feudal system, are derived from the Celtic barbarians. When Cæsar subdued the Gauls, that great nation was already divided into three orders of men; the clergy, the nobility, and the common people. The first governed by superstition, the second by arms, but the third and last was not of any weight or account in their public councils. It was very natural for the plebeians, oppressed by debt, or apprehensive of injuries, to implore the protection of some powerful chief, who acquired over their persons and property the same absolute right as, among the Greeks and Romans, a master exercised over his slaves. The greatest part of the nation was gradually reduced into a state of servitude; compelled to perpetual labor on the estates of the Gallic nobles, and confined to the soil, either by the real weight of fetters, or by the no less cruel and forcible restraints of the laws. During the long series of troubles which agitated Gaul, from the reign of Gallienus to that of Diocletian, the condition of these servile peasants was peculiarly miserable; and they experienced at once the complicated tyranny of their masters, of the barbarians, of the soldiers, and of the officers of the revenue.

Their patience was at last provoked into despair. On every side they rose in multitudes, armed with rustic weapons, and with irresistible fury. The ploughman became a foot soldier, the shepherd mounted on horseback, the deserted villages and open towns were abandoned to the flames, and the ravages of the peasants equalled those of the fiercest barbarians. They asserted the natural rights of men, but they asserted those rights with the most savage cruelty. The Gallic nobles, justly dreading their revenge, either took refuge in the fortified cities, or fled from the wild scene of anarchy. The peasants reigned without control; and two of their most daring leaders had the folly and rashness to assume the Imperial ornaments. Their power soon expired at the approach of the legions. The strength of union and discipline obtained an easy victory over a licentious and divided multitude. A severe retaliation was inflicted on the peasants who were found in arms; the affrighted remnant returned to their respective habitations, and their unsuccessful effort for freedom served only to confirm their slavery. So strong and uniform is the current of popular passions, that we might almost venture, from very scanty materials, to relate the particulars of this war; but we are not disposed to believe that the principal leaders, Ælianus and Amandus, were Christians, or to insinuate, that the rebellion, as it happened in the time of Luther, was occasioned by the abuse of those benevolent principles of Christianity, which inculcate the natural freedom of mankind.

Maximian had no sooner recovered Gaul from the hands of the peasants, than he lost Britain by the usurpation of Carausius. Ever since the rash but successful enterprise of the Franks under the reign of Probus, their daring countrymen had constructed squadrons of light brigantines, in which they incessantly ravaged the provinces adjacent to the ocean. To repel their desultory incursions, it was found necessary to create a naval power; and the judicious measure was prosecuted with prudence and vigor. Gessoriacum, or Boulogne, in the straits of the British Channel, was chosen by the emperor for the station of the Roman fleet; and the command of it was intrusted to Carausius, a Menapian of the meanest origin, but who had long signalized his skill as a pilot, and his valor as a soldier. The integrity of the new admiral corresponded not with his abilities. When the German pirates sailed from their own harbors, he connived at their passage, but he diligently intercepted their return, and appropriated to his own use an ample share of the spoil which they had acquired. The wealth of Carausius was, on this occasion, very justly considered as an evidence of his guilt; and Maximian had already given orders for his death. But the crafty Menapian foresaw and prevented the severity of the emperor. By his liberality he had attached to his fortunes the fleet which he commanded, and secured the barbarians in his interest. From the port of Boulogne he sailed over to Britain, persuaded the legion, and the auxiliaries which guarded that island, to embrace his party,
