Alexander
The Great

Greece and the Balkan Peninsula secured, Alexander
then crossed (334) the Hellespont (now the Dardanelles) and, as
head of an allied Greek army, undertook the war on Persia
that his father had been planning. The march he had begun was
to be one of the greatest in history. At the Granicus River (near
the Hellespont) he met and defeated a Persian force and moved
on to take Miletus and Halicarnassus. For the first time Persia
faced a united Greece, and Alexander saw himself as the spreader
of Panhellenic ideals. Having taken most of Asia Minor, he entered
(333) N Syria and there in the battle of Issus met and routed
the hosts of Darius III of Persia, who fled before him.
Alexander, triumphant, now envisioned conquest of
the whole of the Persian Empire. It took him nearly a year to
reduce Tyre and Gaza, and in 332, in full command of Syria, he
entered Egypt. There he met no resistance. When he went to the
oasis of Amon he was acknowledged as the son of Amon-Ra, and this
may have contributed to a conviction of his own divinity. In the
winter he founded Alexandria, perhaps the greatest monument to
his name, and in the spring of 331 he returned to Syria, then
went to Mesopotamia where he met Darius
again in the battle of Guagamela. The battle was hard, but Alexander
was victorious. He marched S to Babylon,
then went to Susa and on to Persepolis,
where he burned the palaces of the Persians and looted the city.
He was now the visible ruler of the Persian Empire,
pursuing the fugitive Darius to Ecbatana,
which submitted in 330, and on to Bactria.
There the satrap Bessus, a cousin of Darius, had the Persian king
murdered and declared himself king. Alexander went on through
Bactria and captured and executed Bessus. He was now in the regions
beyond the Oxus River (the present-day Amu Darya), and his men
were beginning to show dissatisfaction. In 330 a conspiracy against
Alexander was said to implicate the son of one of his generals,
Parmenion; Alexander not only executed the son but also put the
innocent Parmenion to death. This act and other instances of his
harshness further alienated the soldiers, who disliked Alexander's
assuming Persian dress and the manner of a despot.
Nevertheless Alexander conquered
all of Bactria and Sogdiana after hard
fighting and then went on from what is today Afghanistan into
N India. Some of the princes there received him favorably, but
at the Hydaspes (the present-day Jhelum River) he met and defeated
an army under Porus. He overran the Punjab, but there his men
would go no farther. He had built a fleet, and after going down
the Indus to its delta, he sent Nearchus with the fleet to take
it across the unknown route to the head of the Persian Gulf, a
daring undertaking. He himself led his men through the desert
regions of modern Baluchistan, S Afghanistan, and S Iran. The
march, accomplished with great suffering, finally ended at Susa
in 324
