The Olympic Games are an international event of summer and winter sports, in which thousands of athletes compete in a wide variety of events. The Games are currently held every two years, with Summer and Winter Olympic Games alternating. Originally, the ancient Olympic Games were held in Olympia, Greece, from the 8th century BC to the 5th century AD. In the late 19th century, Baron Pierre de Coubertin was inspired by Olympic festivals to revive the Games. For this purpose, he founded the International Olympic Committee (IOC) in 1894, and two years later, the modern Olympic Games were established in Athens. The IOC has since become the governing body of the Olympic Movement, whose structure and actions are defined by the Olympic Charter.
