Roland had a friend and companion named Oliver, who was as brave as himself. Many stories and songs have been written telling of the wonderful adventures they were said to have had and of their wonderful deeds in war.

The work of Charlemagne in Spain was quickly undone; for Abd-er-Rahman, the leader of the Mohammedans who had come from Damascus, soon conquered almost all the territory south of the Pyrenees.

ROLAND IN THE BATTLE OF RONCESVALLES

For more than forty years Charlemagne was king of the Franks; but a still greater dignity was to come to him. In the year 800 some of the people in Rome rebelled against the Pope, and Charlemagne went with an army to put down the rebellion. He entered the city with great pomp and soon conquered the rebels. On Christmas day he went to the church of St. Peter, and as he knelt before the altar the Pope placed a crown upon his head, saying:

"Long live Charles Augustus, Emperor of the Romans."

The people assembled in the church shouted the same words; and so Charlemagne was now emperor of the Western Roman Empire, as well as king of the Franks.[*]

[Footnote *: The emperors of Constantinople still called themselves Roman Emperors, and still claimed Italy, Germany and France as parts of their empire, though really their authority had not been respected in these countries for more than 300 years.]

Charlemagne built a splendid palace at Aix-la-Chapelle (aks-la-shap-el'), a town in Germany, where perhaps he was born.

Charlemagne was a tall man, with long, flowing beard, and of noble appearance. He dressed in very simple style; but when he went into battle he wore armor, as was the custom for kings and nobles, and often for ordinary soldiers in his day.
