Ancient Olympic Games- According to historical records, the first ancient Olympic Games can be traced back to 776 BC. They were dedicated to the Olympian gods and were staged on the ancient plains of Olympia. They continued for nearly 12 centuries, until Emperor Theodosius decreed in 393 A.D. that all such "pagan cults" be banned. The ancient Greek Olympic Games were initially a one-day event until 684 BC, when they were extended to three days. In the 5th century B.C., the Games were extended again to cover five days. The ancient Games included running, long jump, shot put, javelin, boxing, pankration, (including wrestling) and equestrian events.
