Modern Olympism was conceived by Pierre de Coubertin, on whose initiative the International Athletic Congress of Paris was held in June 1894. The International Olympic Committee (IOC) constituted itself on 23 June 1894. The first Olympic Games (Games of the Olympiad) of modern times were celebrated in Athens, Greece, in 1896. In 1914, the Olympic flag presented by Pierre de Coubertin at the Paris Congress was adopted. It includes the five interlaced rings, which represent the union of the five continents and the meeting of athletes from throughout the world at the Olympic Games. The first Olympic Winter Games were celebrated in Chamonix, France, in 1924.
