What Cultural Ties United the Ancient Greek World?

The ancient Greek, or Hellenistic, world after Alexander the Great — comprising regions as diverse as the Middle East (Syria and Persia), North Africa (Egypt), Greece and Macedonia — was broadly unified by its language, art, literature, religion and philosophy. Cultural ties, particularly between ancient Macedonia and Asia, are believed to have been cultivated by Alexander as part of his strategy of "homonoia" — human unity or fusion — to "hellenize" the lands he conquered.
