THE BATTLE OF IPSUS
 DEMETRIUS, having failed to take Rhodes, now passed
over into Greece, hoping to overthrow Cassander; but
the other kings, growing afraid of him, agreed to help
the ruler of Macedon. They therefore collected a large
army, and forced Demetrius to stop and fight them all
at Ipsus, in Asia Minor.
Here, just twenty years after Alexander's death, his
generals met in a great battle. Seleucus, it is said,
brought a number of fighting elephants, such as Porus
had used, which added much to the confusion and
fierceness of the struggle.
Antigonus, the father of Demetrius, was slain, and
Demetrius himself was defeated, and driven to Ephesus.
The Athenians, who had been his friends and allies as
long as he was prosperous, now basely deserted him.
They declared themselves his enemies, and made a law
whereby any one who spoke well of him, or tried to make
peace with him, should be put to death.
The battle of Ipsus decided the fate of Alexander's
kingdom. It was now divided into four principal parts.
Ptolemy remained master of Egypt, and his family
reigned there many years, until under Cleopatra, the
last of his race, the country fell into the hands of
Seleucus and his descendants, the Seleucidæ, had
the Persian Empire, or Syria and the land between the
Indus and the Euphrates. The capital of this empire
was first Seleucia, near Babylon, and later
Antioch, which became a rich and well-known city.
 Lysimachus was given the kingdom of Thrace, which
however, soon passed into other hands; and Cassander
remained master of Macedon. As for Demetrius, although
he had lost a kingdom at the battle of Ipsus, he soon
managed to conquer another.
In his anger at the Athenians, he first marched against
them, and besieged them in their own city. The
Athenians were frightened, for they knew how well they
deserved punishment; but they resisted as well as they
could, and the siege dragged on for several months.
At the end of this time there was no food left in the
city, and the people suffered greatly from hunger.
Finally they were obliged to yield; and Demetrius rode
into Athens in triumph.
