At the end of the 19th century the French nobleman Pierre de Coubertin [ˈpjer də ˈkʊbɜ:tən] got the idea to bring the Olympic Games back to life. With the help of the people who supported him he organized the first modern Olympic Games. So the Olympic Games returned to our life in 1896. They were a success. Athletes from thirteen countries came to Greece and had competitions in nine sports. Russia took part in them too. Now the number of countries taking part in the Olympic Games is much larger and so is the number of athletic events.Like in ancient times, the Olympic Games take place every four years. In 1926 the tradition of the Win-ter Olympic Games also began. The noble idea of the Games is to make all people friends by meeting on football fields, courts and stadiums and to live in peace. The International Olympic Committee [kəˈmɪti] heads the Olympic movement. Among other things the Committee chooses the place for the coming Olympics. It is a great honour to become an Olympic city. In 1980 Moscow joined the family of Olympic cities and in 2014 Sochi did. The XXII Olympics in Sochi were a huge success.The Olympic Games are probably the most important international sports event. Millions of people watch them all over the world. They support their Olympic teams and favourite athletes who fight peaceful battles in honour of sport. A lot of people enjoy the opening and closing ceremonies of the Olympics, co-lourful and original.Many things have changed but like in ancient times winners of the Olympics become national heroes in their countries.
