l, and prepared to seize the shares of his brothers and
sisters. Looking for aid in this design, he was attracted by the growing
fame of young Rodrigo, and gained his aid in the restoration of Zamora,
which the Moors had destroyed. While thus engaged there came to Rodrigo
messengers with tribute from the five Moorish kings whom he had captured
and released. They hailed the young warrior as Sid, or Cid, and the king,
struck by the title, said that Ruy Diaz should thenceforth bear it; also
that he should be known as campeador or champion.

King Sancho now knighted the young warrior with his own hand, and soon
after made him _alferez_, or commander of his troops. As such he was
despatched against Alfonso, who was soon driven from his kingdom of Leon
and sought shelter in the Moorish city of Toledo. Leon being occupied, the
Cid marched against Galicia, and drove out Garcia as he had done Alfonso.
Then he deprived Urraca and Elvira of the cities left them by their
father, and the whole kingdom was once more placed under a single ruler.

It did not long remain so. Sancho died in 1072, and at once Alfonso and
Garcia hurried back from exile to recover their lost realms. But Alfonso's
ambition equalled that of Sancho. All or none was his motto. Invading the
kingdom of Galicia, he robbed Garcia of it and held him prisoner. Then he
prepared to invade Castile, and offered the command of the army for this
enterprise to the Cid.

The latter was ready for fighting in any form, so that he could fight with
honor. But there was doubt in his mind if service under Alfonso was
consistent with the honor of a knight. King Sancho had been assassinated
while hunting, and it was whispered that Alfonso had some share in the
murder. The high-minded Cid would not draw sword for him unless he swore
that he had no lot or part in his brother's death. Twice the Cid gave him
the oath, whereupon, says the chronicle, "My Cid repeated the oath to him
a third time, and the king and the knights said 'Amen.' But the wrath of
the king was exceeding great; and he said to the Cid, 'Ruy Diaz, why dost
thou press me so, man?' From that day forward there was no love towards My
Cid in the heart of the king."

But the king had sworn, and the Cid entered his service and soon conquered
Castile, so that Alfonso became monarch of Castile, Leon, Galicia, and
Portugal, and took the title of Emperor of Spain. As adelantado, or lord
of the marches, Ruy Diaz now occupied hi
