republican side, and laws were passed to bring Cæsar to trial for his breaches of law and his disobedience to the decrees of the Senate.
It was illegal for a general to bring his troops out of the boundary of his command, and the boundary between Cæsar’s command and Italy was the Rubicon. In 49 B.C. he crossed the Rubicon, saying “The die is cast” and marched upon Pompey and Rome.
It had been the custom in Rome in the past, in periods of military extremity, to elect a “dictator” with practically unlimited powers to rule through the crisis. After his overthrow of Pompey, Cæsar was made dictator first for ten years and then (in 45 B.C.) for life. In effect he was made monarch of the empire for life. There was talk of a king, a word abhorrent to Rome since the expulsion of the Etruscans five centuries before. Cæsar refused to be king, but adopted throne and sceptre. After his defeat of Pompey, Cæsar had gone on into Egypt and had made love to Cleopatra, the last of the Ptolemies, the goddess queen of Egypt. She seems to have turned his head very completely. He had brought back to Rome the Egyptian idea of a god-king. His statue was set up in a temple with an inscription “To the Unconquerable God.” The expiring republicanism of Rome flared up in a last protest, and Cæsar was stabbed to death in the Senate at the foot of the statue of his murdered rival, Pompey the Great.
Thirteen years more of this conflict of ambitious personalities followed. There was a second Triumvirate of Lepidus, Mark Antony and Octavian Cæsar, the latter the nephew of Julius Cæsar. Octavian like his uncle took the poorer, hardier western provinces where the best legions were recruited. In 31 B.C., he defeated Mark Antony, his only serious rival, at the naval battle of Actium, and made himself sole master of the Roman world. But Octavian was a man of different quality altogether from Julius Cæsar. He had no foolish craving to be God or King. He had no queen-lover that he wished to dazzle. He restored freedom to the Senate
