42—The republican and aristocratic conspirators were defeated by Augustus and Antony at Philippi, in Greece. Brutus and Cassius, the republican leaders, and assassins of Cæsar, were slain. The second “Triumvirate,” composed of Augustus, Antony and Lepidus, having acquired possession of all the powers of the state, ruthlessly murdered thousands of their political enemies. They soon grew jealous of each other, and fought and intrigued for eleven years, Augustus, with great prudence, firmly settling himself in Rome, and Antony becoming the slave of the beautiful and infamous Cleopatra, queen of Egypt. 31—At length, at the battle of Actium, Antony was defeated, and soon after both Antony and Cleopatra committed suicide. Egypt became formally a Roman province, and Augustus absolute emperor of the world. SECTION IX. THE ROMAN EMPIRE. 1. B. C. 28—In this year Augustus, having fully consolidated his power, was formally recognized emperor. During all the contests of factions, and when Rome was itself in the throes of revolution, the subjection of all the provinces to the imperial city, and whoever was in power there, was rigorously maintained. The inhabitants were protected from invasion, and if they were often oppressed by Roman governors, it was far less than under their native rulers, and, in general, they were not desirous of a change. Roman law and order, and the power of appeal from great injustice to the Roman senate or emperor, maintained a state of generally tranquil prosperity, only disturbed by the contests of rivals for the control of the imperial city and its power. A long period of almost absolute quiet followed the establishment of the empire, which gave Rome and Italy great satisfaction, after nearly a hundred years of civil war. It is called the “Augustan Age,” when industry and commerce, literature and the arts, reached their highest development.
