The Roman conquest and civilization—or rather assimilation—of North Africa were slow, tentative and reluctant. Scipio Æmilianus burnt Carthage in 146 B.C.; it was more than a hundred years later that Julius Cæsar handed over Cirta to the soldiers of Sittius. Under Augustus a camp was established at Theveste (Tebessa), and the Third Legion, Augusta, was stationed there with the object of protecting the territory of Cirta, and the proconsular province which is now Tunisia. Under the shelter of this post, during the first century of our era, the great corn lands enclosed by the Aurès mountains were gradually brought under Roman control. The building of Thamagudi in the reign of Trajan, in the year A.D. 100, is evidence of the importance to which this region had by that time risen. This process continued during the next two centuries. No doubt as the population of Italy declined, and her fertility decreased, Rome came to rely more and more on the corn of Africa, and more land was continually brought under cultivation. This is the significance of such a city as Timgad, lying over 3000 feet above the sea on a slope of the Aurès mountains. Our ideas of the Roman Empire are perhaps coloured by the title of Gibbon’s great work. We are disposed to think that its decline began with its establishment. Gibbon had always at the back of his mind the belief that Christianity was the cause of its ultimate ruin, and that the Empire began to totter on the day when the first Roman citizen was baptised a Christian. But for two or three hundred years, though the Empire was frequently torn by political dissensions, its material prosperity was very great. We know now that it was ruined in the end by its financial errors, its unwise and unjust system of land taxation, the grasping greed of Treasury officials and the anxiety of upstart Emperors to gratify their supporters in the army and the Roman mob at anybody’s cost. It is a vice of civilizations to believe themselves invulnerable. As late as the fifth century it was inconceivable to a Roman gentleman that the mighty structure could be swept away; and it is perhaps true that even then it might have been saved by a return to sounder systems of finance. Even so to-day the European nations are arming to the teeth against each other, instead of husbanding their resources and concerting measures of defence against races more numerous and more prolific. The uprising of the Asiatic peoples is a fact to which we cannot be other than wilfully blind. A beginning of the trouble may be upon us at any minute.
