There is no agreement on when the Games officially ended, but many historians think it is 393 AD, when the Christian Roman emperor Theodosius I declared that all Pagan religious practices should end. Another date might be 426 AD, when the next emperor Theodosius II ordered the destruction of all Greek temples. The stadium in Olympia got buried by landslides and other natural disasters. After the Olympics stopped, they were not held again until the modern Olympic Games were started in 1896 in Athens.
