The ancient Olympic games were a series of athletic competitions among the city-states of ancient Greece one of the Pan-Hellenic games. This was held in the honour of Zeus which was the origins of the mythology. The tradition dated for the first was in 776 B.C. They continued the celebration and tradition when Greece came under Roman rule, until the Emperor Theodosius. While Christianity was the state religion of Rome, the games were held every four years or Olympiad.
During the events for the Olympics a truce was in place for athletes to travel to cities in safety, the victories were olive leaf or crowns. But the games became a political alliance in times of wars, priests would usually offer sacrifices to gods for victory. This was a widespread for games in the Hellenistic culture throughout the Mediterranean world. Which featured religious and artistic competitions. Artists and thinkers, would display their work.
The ancient Olympics had fewer events, and only free-born Greeks were allowed to play, although women appear to have been mentioned.
