4. Return of the King

In Richard Miles's epic story of civilization, there have been plenty of examples of the great men of history, but none came close to the legend of Alexander of Macedon, known to us as 'the Great'. Uniting the fractious Greek city-states, he led them on a crusade against the old enemy, Persia, and in little more than a decade created an empire that stretched from Egypt in the west to Afghanistan in the east.\n\nBut it was Alexander's successors, the Hellenistic Kings, who had to make sense of the legacy of this charismatic adventurer. By knuckling down to the hard graft of politics, taxation and public works, they created something far more enduring than a mere legend - they built a civilization.\n\nRichard traces Alexander's battle-scarred route through Turkey, Syria and Lebanon to Egypt and ultimately to the western Punjab, Pakistan, where he discovers fascinating traces of a city where Greek west and Buddhist east were united in an intriguing new way.
