The first Olympics in the city of Olympia in Greece took place in 776 BC. They continued to be celebrated when Greece came under Roman rule, until the emperor Theodosius I suppressed them in AD 393 as part of the campaign to impose Christianity as the State religion of Rome. The games were held every four years, or olympiad, which became a unit of time in historical chronologies.
