The world's greatest international sports games are known as the Olympic Games.
The Olympic idea means friendship, fraternity and cooperation among the people of the world. The Olympic Movement proves that real peace can be achieved through sport.
The Olympic emblem is five interlinked rings: blue, yellow, black, green and red. Any national flag contains at least one of these colours.
The original Olympic Games began in ancient Greece in 776 B.C. These games were part of a festival held every fourth year in honour of God Zeus at the place called Olympia. It was a great athletic festival, including competitions in wrestling, foot racing and chariot racing, rowing and others.
The games were for men only. Greek women were forbidden not only to participate but also to watch the Olympics.
The first modern Olympic Games were held in Athens in 1896. Then they were resumed in London after the Second World War. Since then the Olympics are held every fourth year in different countries.
The ancient Greeks had no winter sports. Only in 1924 the first Winter Olympic Games were held in France. Now they are being held regularly.
