The marriage was celebrated with great pomp and the king gave Rodrigo four cities as a marriage portion. Rodrigo, vowing that he would not be worthy of his wife until he had won five battles, after a pious pilgrimage to the shrine of the patron saint, hastened off to Calahorra, a frontier town claimed by two kings—the kings of Castile and Oregon.

It had been decided that the dispute over the town should be settled by combat. Rodrigo became the champion of Ferdinand of Castile. The other champion, Martin Gonzalez, began, as soon as the combat opened, to taunt the Cid.

"Never again will you mount your favorite steed Babieça," he said, "never will you return to your castle; never will you see your beloved Ximena again."

But the Cid was undaunted, and had soon laid his enemy low. Great praise then was given to the Cid—so great that the knights of Castile were jealous and plotted to kill him. But the Moorish kings whom he had captured and released warned him in time to avert the danger.

Then the Cid aided Ferdinand in defeating the hostile Moors in Estremadura, after a siege of Coimbra lasting seven months. Several other victories over his country's enemies were added to this, and then Rodrigo returned to his beloved wife.

But not for long was he permitted to remain in the quiet of home. Henry III, Emperor of Germany, complained to the Pope that King Ferdinand had refused to acknowledge his superiority. The Pope sent a message to Ferdinand, demanding homage and tribute. The demand angered both Ferdinand and the Cid.

"Never yet have we done homage," cried the Cid, "and shall we now bow to a stranger?"

A proud refusal was then sent to the Pope, and he, knowing of no better way to settle the dispute, bade Henry send a champion to meet Rodrigo. The emperor's champion was, of course, defeated, and all of Ferdinand's enemies were so awed by the outcome of the fight that none ever again demanded homage or tribute. Rodrigo was, indeed, a very useful subject. When Ferdinand died, he was succeeded by his son, Don Sancho. The latter, planning a visit to Rome, selected the Cid to accompany him. Arriving, they found that in the preparations that had been made for their reception a lower seat had been prepared for Don Sancho than for the King of France. The Cid would not suffer such a slight, and became so violent that the Pope excommunicated him. Nevertheless, the seats were made of equal height, and the Cid, who was a good Catholic, humbled himself before the Pope and was forgiven.

It was an age of great wars, and the Cid aided his king in many a brave fight. At last, in the siege of Zamora, the king was treacherously murdered, and, as he had no sons, Don Alfonso, his brother, succeeded. When he arrived at Zamora the Cid refused to acknowledge Alfonso until he should swear that he had no part in the murder. The king, angered by the Cid's attitude, plotted revenge. Opportunity came during a war with the Moors, and the Cid was banished upon a slight pretext.

"I obey, O king," replied the Cid, when he heard the decree. "I am more ready to serve you than you are to reward me. I pray that you may never more in battle need the right arm and sword that so often served your father."
