Then the Senate, wildly afraid that Cæsar would return at the head of his troops and become a tyrant like Sulla, declared war against Cæsar and put in Pompey's hands the task of humbling his former friend. Cæsar had no intention of disbanding his troops. His soldiers loved him deeply and would follow wherever he led them. And Cæsar exhorted his men to stand by him, promising them honor and riches if he should succeed in overcoming his enemies at Rome, and the men with wild cheers swore that they would follow him to the death.
At the head of a powerful and well disciplined army that was devoted to him, Cæsar advanced on Rome. When he came to a stream called the Rubicon, which marked the limit of his power as governor of Gaul, he hesitated for a brief time, as there was still time for him to draw back from his tremendous venture had he seen fit to do so—but at length he plunged into the stream with the remark, "The die is cast," and advanced upon the city that he intended to win for himself.
Pompey had been through an exceedingly hard time in getting soldiers to follow his banner, for the reputation of Cæsar was very formidable and his army even more so. Finding that it was impossible to make a stand against Cæsar in Italy, Pompey fled across the Mediterranean Sea, leaving Cæsar the master of Rome and Italy as well. Cæsar, however, was not in the habit of leaving an enemy to fly unmolested. He pursued Pompey to Thessaly and there fought a battle against him in which Pompey was utterly defeated and his soldiers scattered and routed. Pompey fled to Egypt, where Cæsar followed him—and the first thing that was brought to Cæsar when he arrived was Pompey's head. The once great Roman had been treacherously murdered by the Egyptians, who believed that in so doing they would curry favor with Cæsar.
In Egypt there was a beautiful queen named Cleopatra, who used all her great art to force Cæsar to fall in love with her. She believed that when he loved her he would place her firmly on the Egyptian throne and send the Roman soldiers against her enemies. So completely did she succeed that Cæsar, who never had been averse to the charms of beautiful women, remained at her court for a considerable time and led his armies against a king named Pharnaces at Cleopatra's bidding. After this he returned to Rome, where he was made dictator, with absolute power, and was as great as Sulla had ever been.
But there were still a number of Romans who refused to submit to his power, and Cæsar was compelled to go once more to Africa to vanquish Pompey's friends, Scipio and Cato, who were raising a new army against him. With his usual military genius, he overthrew them easily and returned again to Rome.
Nothing in Roman history equalled his welcome there. He was received as a returning king and the honors that were heaped upon him were greater than had been given to any other Roman in all the long centuries that Rome had been a city. He was called "Father of His Country" and had a bodyguard of Roman noblemen to accompany him wherever he went. His person was considered sacred, and the month of Quintilis was called after his name, July, for Julius, the name it has borne from that far time to the present day.
Now, in his hour of triumph and greatness, Cæsar showed himself of far different mettle from any Roman who had previously gained power over the state. He did not mar his success by murdering his enemies as Sulla had done, but rather sought to be the friend of all, and busied himself with good deeds and public works that would benefit the people. And while a royal crown was offered to him many times,—notably by the same Marc Antony who had fled to his camp as a fugitive when the Senate rose against his power—Cæsar refused to accept it, believing that he could govern wisely and temperately without the name of King, which was bitter in the ears of all true Romans.
However, his kindness did not save him, and his glory was short lived. Certain Romans considered that their state had fallen under the power of a tyrant, and believed that Rome could be brought back to its former freedom by Cæsar's death. A conspiracy was hatched against him among the senators, and one of its leaders was a man named Brutus, to whom Cæsar had shown every kindness. Brutus, with his comrade, Cassius, and some sixty others held secret meetings at night in which they discussed the best way to murder Cæsar, and it was finally decided that they would fall upon him with swords and daggers when he entered the Senate House.
In connection with this evil plot a strange thing happened. Cæsar was approached by an old man who claimed to be a prophet or a soothsayer. This man warned him that on a certain day, which began what was called the Ides of March, he must not stir out of his house or evil would come to him. Cæsar laughed at this prediction, but on the night before this very day, his wife, Calpurnia, had an evil dream in which she beheld specters walking in the streets of Rome; and she begged Cæsar as he loved her to remain at home. Cæsar was about to give in to her request when Brutus called at his house to take him to the Senate, and, knowing of the conspiracy, of which he was one of the leaders, Brutus ridiculed Cæsar for being frightened by the dream of his wife and persuaded him to go, although Calpurnia wept bitterly when he departed, believing that she would never see him again.
On the way to the Senate Cæsar passed the soothsayer, and remembering his prediction called out to him that the Ides of March were come.
