The Roman Empire reached its greatest extent under Marcus Ulpius Traianus, the fourteenth emperor. Of him it was said that he "built the world over," and the Romans themselves regarded him as the best, and perhaps the greatest of their emperors. He was a native of Italica, in Spain. The family to which he belonged was probably Italian, and not Iberian, by blood. His father began life as a common legionary soldier, and fought his way up to the consulship and the governorship of Asia. He was one of the hardest fighters in Judaea under Vespasian and Titus; he served, too, against the Parthians, and won the highest military distinction open to a subject, the grant of the triumphal insignia. Thus he acquired a prominent place among the brand new patricians created by the Flavians as substitutes for the nobles of old descent who had succumbed to the cruelty and rapacity of the emperors from Tiberius to Nero. The younger Trajan was rigorously trained by his father, and deeply imbued with the same principles and tastes. He was a soldier born and bred. No better representative of the true old hardy Roman type, little softened either by luxury or education, had come to the head of affairs since the days of Marius. The date of his birth was probably 53 A.D. His training was almost exclusively military, but his experience as an officer gave him an acquaintance with almost every important province of the empire, which was of priceless value to him when he came to the throne. For ten years he held a commission as military tribune, which took him to many lands far asunder; then he filled important posts in Syria and Spain. How much actual warfare Trajan saw in those days we can hardly tell; he certainly went through some severe service under his father's command against the Parthians. By the year 89 he had achieved a considerable reputation. At that time L. Antonius Saturninus headed a rebellion in Germany, which threatened seriously to bring Domitian's rule to an end. Trajan was ordered in hot haste from Farther Spain to the Rhine. Although he carried his troops over that long and arduous march with almost unexampled rapidity, he only arrived after the insurrection had been put down. But his promptitude raised him higher in the favor of Domitian, and he was advanced to the consulship in 91. Of the next five years of his life we know nothing positively. It is not unlikely that they were spent at Rome or in Italy in the fulfilment of some official duties.
