In The Footsteps Of Alexander The Great

Alexander remains one of the most well-known figures of Antiquity. He was one of the most successful military commanders in history, and he is usually considered to have been undefeated in battle. The states that emerged from Alexander's conquests lasted for centuries after his death, however, his cultural influence proved even more enduring. Alexander became the measure against which generals still compare themselves and his tactical exploits are taught in military academies throughout the world. Alexander's achievements very quickly became legendary, and he features prominently in both the history and myth of Greek and non-Greek cultures. The life of Alexander inspired its own literary tradition, in which he appeared as a legendary hero in the mould of Achilles.
