Since then (the beginning of history of emergence of the Olympic Games — is short — read HERE) the Olympic Games are held each four years. In 1906 in honor of a decade of the first recreated Olympic Games passed extraordinary games – in Athens. However because of wars the Olympic Games didn't take place VI (1916), XII (1940), XIII (1944). Athletes of our country for the first time participated in the IV Olympic Games in 1908. The team was small – only 5 people, but it didn't prevent them to receive one gold and two silver medals. Secondary speech of our athletes took place at the following Olympic Games. And then, because of revolution, wars and other civil problems, athletes of our country could participate only in the XV Olympic Games of 1952 in Helsinki (in informal offset athletes from Russia divided the first place with a team of the USA). Olympic Games till 1924 included only summer sports though sometimes they joined hockey and figure skating on the skates. In 1924 in Shamoni (France) for the first time passed the independent winter Olympic Games. Further they began to be carried out already regularly at the beginning of the same year, as summer. Athletes from the USSR for the first time participated only in the VII winter Olympic Games in which came out winners (7 gold, 3 silver and 6 bronze medals). The following winter games in Squaw Valley (USA) brought to our athletes 21 medals (7 gold, 5 silver and 9 bronze). In February, 2014 in Sochi (Russia) XXII Winter Olympic games will be held, in which sportmen will pass competitions in 7 winter sports.
