What was bad about Hellenization?

Answer 1

• There were some among the Greeks who resented the influx of non-Greek elements into Greek culture (Hellenization was not a one-way street). This created some degree of conflict among the Greeks themselves (Professor Peter Green, in "Alexander to Actium").
• The native Greeks often considered themselves superior to others, whom they sometimes persecuted or subjected to discrimination (ibid).
• The Greeks brought their pantheon and their legal code to the lands which they colonized, including whatever excesses that these contained.

• To those peoples who had been steadfastly religious, the Greek concepts of agnosticism (from the Sophists) and materialism (from the Epicurians) were now introduced.
• Some of the ancients viewed Hellenization as a decline and as a reduction in freedom and excellence (Herodotus, quoted in T. Holland's "Persian Fire").

Answer 3

Hellenization led to the loss of cultural and religious diversity as Greek culture and customs were imposed on other societies. It also resulted in the suppression of local languages and traditions, causing resentment and unrest among the native populations. Additionally, Hellenization contributed to social inequality and discrimination against non-Greek populations.
