The Olympic Council (Olympike Boule) was the supreme collective body of the city-state of Elis responsible for the administration and oversight of the sanctuary. It was composed of prominent citizens and initially possessed an oligarchic structure, consisting primarily of wealthy landowners. Following the synoikismos (unification) of Elis in 471 BC, the Council adopted more democratic characteristics, similar to those of Athens, while remaining the principal administrative and consultative body. While the exact number of members is not recorded for all periods, the discovery of a bronze ballot marked with the number 175 suggests the possible size of the body during the Roman era.
The seat of the Council was the Bouleuterion, located south of the Temple of Zeus, outside the sacred enclosure of the Altis. This complex served as an archive, housing official documents such as Elean laws, international treaties, proxeny decrees, and lists of Olympic victors. In this space stood the statue of Zeus Horkios (Zeus of the Oath), before which athletes, their relatives, and trainers took a sacred oath to compete honorably and follow the rules.
he Council supervised all religious ceremonies and, often in conjunction with the “Demos of the Eleans,” authorized the erection of honorary statues for benefactors or Olympic victors. Furthermore, it functioned as an international center for arbitration, resolving territorial or political disputes between other Greek city-states, such as a land dispute involving Xenophon in the 4th century BC
