Pelops was a king who founded the Olympic Games. The first recorded Olympics were in 776 BCE where a cook named Coroebus won the sole event, a 192m run, making him the first Olympic champion. The Hellanodikai were judges who enforced rules and organized the games, selecting winners to receive olive wreath crowns. Zeus was the most important Olympic god. The ancient Olympics had fewer events than modern ones, including running, wrestling, and chariot racing. The games ended in 393 AD when the Roman emperor outlawed them to help establish Christianity as the state religion.
