Who banned the ancient olympic games?

Answer 1

Theodosius I attempted to ban all Olympic games in ancient Greece, although he may not have been entirely successful. He declared the ban in 394 AD as part of a larger ban on pagan celebrations and rituals.

Answer 2

Unlike how our Olympics are today, judges did not come from all over. They were drawn from Elis, the local region which included Olympia. The number of judges increased to 10 as more events were added to the Ancient Olympic Games.
