The Panhellenion (Greek: Πανελλήνιον) or Panhellenium was a league of Greek city-states established in the year 131–132 AD by the Roman EmperorHadrian while he was touring the Roman provinces of Greece. The League was established following a ceremony at the Temple of Olympian Zeus in Athens, the capital city of the Panhellenion. Evidence suggests that the Panhellenion continued to survive until the 250s AD.[1]
The Panhellenion was primarily a religious organization, and most of its deeds were related to self-governance. Admission to the Panhellenion was subject to the scrutiny of a city's Hellenic descent.[citation needed]
