and people of Rome. He declined to be dictator. The grateful Senate in return gave him the reality instead of the forms of power. He was to be called not King indeed, but “Princeps” and “Augustus.” He became Augustus Cæsar, the first of the Roman emperors (27 B.C. to 14 A.D.).
He was followed by Tiberius Cæsar (14 to 37 A.D.) and he by others, Caligula, Claudius, Nero and so on up to Trajan (98 A.D.), Hadrian (117 A.D.), Antonius Pius (138 A.D.) and Marcus Aurelius (161- 180 A.D.). All these emperors were emperors of the legions. The soldiers made them, and some the soldiers destroyed. Gradually the Senate fades out of Roman-history, and the emperor and his administrative officials replace it. The boundaries of the empire crept forward now to their utmost limits. Most of Britain was added to the empire, Transylvania was brought in as a new province, Dacia; Trajan crossed the Euphrates. Hadrian had an idea that reminds us at once of what had happened at the other end of the old world. Like Shi-Hwang-ti he built walls against the northern barbarians; one across Britain and a palisade between the Rhine and the Danube. He abandoned some of the acquisitions of Trajan.
The expansion of the Roman Empire was at an end.
