The Summer Olympic Games are the largest international competitions in summer and all-season sports, held once every 4 years under the auspices of the International Olympic Committee (IOC).
Games began to be held in 1896.
The revival of the Olympic movement in modern times is associated with the name of Baron Pierre de Coubertin.
Countries that have hosted the Games once are marked in green. Countries that have hosted the Games two or more times, in blue.
