As subjects of a foreign king, the Athenians would never have had the opportunity to develop their unique democratic culture. Much that made Greek civilisation distinctive would have been aborted. The legacy inherited by Rome and passed on to modern Europe would have been immeasurably impoverished. Not only would the West have lost its first struggle for independence and survival, but it is unlikely, had the Greeks succumbed to Xerxes’ invasion, that there would ever have been such an entity as ‘the West’ at all.
