"As there is but one God in heaven, " he said, "there ought to be but one ruler on the earth."

So he gathered an immense army from all parts of his dominion, and for weeks his subjects were busy making preparations for war. At length he started for Persia in command of a splendid army. After gaining some brilliant victories he forced the Persian king to flee from his capital.

All the rich country belonging to Persia , from the Tigris to the Euphrates , submitted to the Mongolian conqueror.

Tamerlane celebrated his Persian conquest by magnificent festivities which continued for a week. Then orders were given to march into the great Tatar empire of the North. Here Tamerlane was victorious over the principal chiefs and made them his vassals. In pursuing the Tatars he entered Russia and sacked and burned some of the Russian cities. He did not, however, continue his invasion of this country, but turned in the direction of India .

At last his army stood before the city of Delhi , and after a fierce assault forced it to surrender. Other cities of India were taken and the authority of Tamerlane was established over a large extent of the country.

Bajazet (baj-a-zet'), sultan of Turkey , now determined to stop Tamerlane's eastward march.

News of this reached the conqueror's ears. Leaving India , he marched to meet the sultan. Bajazet was a famous warrior. He was so rapid in his movements in war that he was called "the lightning."

Tamerlane entered the sultan's dominions and devastated them. He stormed Bagdad , and after capturing the place killed thousands of the inhabitants.

At length the rivals and their armies faced each other. A great battle followed. It raged four or five hours and then the Turks were totally defeated. Bajazet was captured.

Tamerlane then ordered a great iron cage to be made and forced the sultan to enter it. The prisoner was chained to the iron bars of the cage and was thus exhibited to the Mongol soldiers, who taunted him as he was carried along the lines.

As the army marched from place to place the sultan in his cage was shown to the people. How long the fallen monarch had to bear this humiliating punishment is not known.

Tamerlane's dominions now embraced a large part of Asia . He retired to his palace at Samarcand and for several weeks indulged in festivities.

He could not, however, long be content away from the field of battle. So he made up his mind to invade the Empire of China. At the head of a great army of two hundred thousand soldiers he marched from the city of Samarcand towards China . He had gone about three hundred miles on the way when, in February, 1405, he was taken sick and died. His army was disbanded and all thought of invading China was given up.

Thus passed away one of the greatest conquerors of the Middle Ages. He was a soldier of genius but he cannot be called a truly great man. His vast empire speedily fell to pieces after his death. Since his day there has been no leader like him in that part of Asia .

Of all the kings that England ever had Henry V was perhaps the greatest favorite among the people. They liked him because he was handsome and brave and, above all, because he conquered France .

In his youth, Prince Hal, as the people called him, had a number of merry companions who sometimes got themselves into trouble by their pranks. Once one of them was arrested and brought before the chief justice of the kingdom.

Prince Hal was not pleased because sentence was given against his companion and he drew his sword, threatening the judge. Upon this the judge bravely ordered the prince to be arrested and put into prison.

Prince Hal submitted to his punishment with good grace and his father is reported to have said, "Happy is the monarch who has so just a judge, and a son so willing to obey the law."

One of Prince Hal's companions was a fat old knight named Sir John Falstaff. Once Falstaff was boasting that he and three men had beaten and almost killed two men in buckram suits who had attacked and tried to rob them. The prince led him on and gave him a chance to brag as much as he wanted to, until finally Falstaff swore that there were at least a hundred robbers and that he himself fought with fifty. Then Prince Hal told their companions that only two men had attacked Falstaff and his friends, and that he and another man who was present were those two. And he said that Falstaff, instead of fighting, had run as fast as his legs could carry him.

There was real goodness as well as merriment in Prince Hal. And so the people found; for when he became king on the death of his father he told his wild companions that the days of his wildness were over; and he advised them to lead better lives in future.

As Henry V, Prince Hal made himself famous in English history by his war with France .

Normandy , you remember, had belonged to Henry's ancestor, William the Conqueror. It had been taken from King John of England by the French king, Philip Augustus, in 1203.

Soon after his coronation Henry sent a demand to the French king that Normandy should be restored, and he made the claim which his great-grandfather, Edward III, had made that he was by right the king of France .

Of course, the king of France would not acknowledge this. Henry therefore raised an army of thirty thousand men and invaded France .

Before he began to attack the French he gave strict orders to his men that they were to harm no one who was not a soldier and to take nothing from the houses or farms of any persons who were not fighting.

Sickness broke out among Henry's troops after they landed, so that their number was reduced to about fifteen thousand. Fifty or sixty thousand Frenchmen were encamped on the field of Agincourt (azh-an-koor') to oppose this little army.

The odds were greatly against Henry. The night before the battle one of his officers said he wished that the many thousand brave soldiers who were quietly sleeping in their beds in England were with the king.

"I would not have a single man more, " said Henry. "If god give us victory, it will be plain we owe it to His grace. If not, the fewer we are the less loss for England ."

The men drew courage from their king. The English archers poured arrows into the ranks of their opponents; and although the French fought bravely, they were completely routed. Eleven thousand Frenchmen fell. Among the slain were more than a hundred of the nobles of the land.

Agincourt was not the last of Henry's victories. He brought a second army of forty thousand men over to France . Town after town was captured, and at last Henry and his victorious troops laid siege to Rouen , which was then the largest and richest city in France .
