Due to the absence of concrete historical records, it is challenging to ascertain the exact starting point of the ancient Olympic games. However, historians generally attribute the first recorded Olympic victor, Koroibos of Elis, to the year 776 B.C. The games continued to flourish and evolve over the centuries, even as Greece’s influence waned and Rome rose to prominence.
During the Hellenistic and Roman periods, political and economic shifts affected both the Olympic site and the games themselves. Nonetheless, some Roman emperors, recognizing the cultural significance of the games, revived their splendor and undertook restoration efforts at the site.By the 3rd century A.D., uncertainties surrounding the lists of victors began to arise, and by the end of that century, the lists ceased to exist entirely.
The official end of the ancient Olympic games came when the emperor Theodosius I, after adopting Christianity as the state religion, issued a decree in 393 or 394 A.D. abolishing all pagan religious practices. Since the Olympics were deeply intertwined with the worship of Zeus, they fell victim to this prohibition.
