Hellenization (American English) or Hellenisation (British) is the historical spread of ancient Greek culture and, to a lesser extent, language, over foreign peoples conquered by Greece or brought into its sphere of influence, particularly during the Hellenistic period following the campaigns of Alexander the Great (king of Macedon, r. 336–323 BCE). The result of Hellenisation was that elements of Greek origin combined in various forms and degrees with local elements; these Greek influences spread from the Mediterranean basin as far east as modern-day Pakistan. In modern times, Hellenisation has been associated with the adoption of modern Greek culture and the ethnic and cultural homogenization of Greece.
