Alexander the Great, the young Macedonian military genius who forged an empire stretching from the eastern Mediterranean to India, dies in Babylon, in present-day Iraq, at the age of 33.
Two years later, the young king led a large army into Asia Minor to carry out his father's plans for conquering Persia. Consistently outnumbered in his battles against superior Persian forces, Alexander displayed an unprecedented understanding of strategic military planning and tactical maneuvers. He never lost a single battle, and by 330 B.C. all of Persia and Asia Minor was under his sway.
Within his empire, he founded great and lasting cities, such as Alexandria in Egypt, and brought about sweeping political and economic changes based on the advanced Greek models taught to him in his youth.
Although Alexander controlled the largest empire in the history of the world, he launched a new eastern campaign soon after his return from Persia. By 327 B.C., he had conquered Afghanistan, Central Asia, and northern India. In the next year, his army, exhausted after eight years of fighting, refused to go farther, and Alexander led them on a difficult journey home through the inhospitable Makran Desert.
Finally reaching Babylon, Alexander began constructing a large fleet to take his army back to Egypt. However, in June 323 B.C., just as the work on his ships was reaching its conclusion, Alexander fell sick after a prolonged banquet and drinking bout and died.
