[13] The peaceful system of his predecessors was interrupted by scenes of war and conquest; and the legions, after a long interval, beheld a military emperor at their head.
The first exploits of Trajan were against the Dacians, the most warlike of men, who dwelt beyond the Danube, and who, during the reign of Domitian, had insulted, with impunity, the Majesty of Rome.

[14] To the strength and fierceness of barbarians they added a contempt for life, which was derived from a warm persuasion of the immortality and transmigration of the soul.

[15] Decebalus, the Dacian king, approved himself a rival not unworthy of Trajan; nor did he despair of his own and the public fortune, till, by the confession of his enemies, he had exhausted every resource both of valor and policy.

[16] This memorable war, with a very short suspension of hostilities, lasted five years; and as the emperor could exert, without control, the whole force of the state, it was terminated by an absolute submission of the barbarians.
[17] The new province of Dacia, which formed a second exception to the precept of Augustus, was about thirteen hundred miles in circumference.
Its natural boundaries were the Niester, the Teyss or Tibiscus, the Lower Danube, and the Euxine Sea.

The vestiges of a military road may still be traced from the banks of the Danube to the neighborhood of Bender, a place famous in modern history, and the actual frontier of the Turkish and Russian empires.
