The earliest record of this games goes back to 776 BC. The ancient Games were held in honour of Zeus the most important god for  ancient Greeks. According to the earliest recordis, only one athletic event was held in the ancient Olympics-a footrace of about 183 metres, or the lengeth of the stadiom. A cook, Coroibus of Elis, was the recorded winner. Only men were allowed to compete or watch the games. When the powerful, warlike Spartans began to compete, they changed the programme of the Games. The 18th Olympics already included wrestling and pentathlon, and later Games-chariot races and other sports. The winners of the Games were heighly praised and honoured for their results. In 394 AD the Gameswere officially ended by the Roman emperor Theodosius, who felt that they had pagan meaning.

With the help of the people who supported him he managed to organize the first modern Olympic Gamec in 1896.

The nine countries were Belgium, England, France, Greece, Italy,Russia, Spain, Sweden and United States. They agreed that every four world.

Russia took the second place with 26 gold, 21 silver and 16 bronse medalce.
