Harun was as good as his word. He started that day with a large army to punish the emperor. As soon as he reached Roman territory he ravaged the country and took possession of everything valuable that he found. He laid siege to Her-a-cle'a, a city on the shores of the Black Sea, and in a week forced it to surrender. Then he sacked the place.

Nicephorus was now forced to agree to pay the tribute. Scarcely, however, had the caliph reached his palace in Bagdad when the emperor again refused to pay.

Harun, consequently, advanced into the Roman province of Phrygia, in Asia Minor, with an army of 15,000 men. Nicepherus marched against him with 125,000 men. In the battle which followed the emperor was wounded, and 40,000 of his men were killed.

After this defeat Nicephorus again promised payment of the tribute, but again failed to keep his promise.

Harun now vowed that he would kill the emperor if he should ever lay hands upon him. But as he was getting ready to march once more into the Roman provinces a revolt broke out in one of the cities of his own kingdom; and while on his way to suppress it the great caliph died of an illness which had long given him trouble.

EGBERT

KING FROM 802-837 A.D.

I

Egbert the Saxon lived at the same time as did Harun-al-Rashid and Charlemagne. He was the first king who ruled all England as one kingdom. Long before his birth the people who are known to us as Britons lived there, and they gave to the island the name Britain.

But Britain was invaded by the Romans under Julius Cæsar and his successors, and all that part of it which we now call England was added to the Empire of Rome. The Britons were driven into Wales and Cornwall, the western sections of the island.
