The 1908 Summer Olympics, officially the Games of the IV Olympiad, were an international multi-sport event which was held in 1908 in London. These games were originally scheduled to be held in Rome. At the time they were the fifth modern Olympic games. However, the Athens Games of 1906 have since been downgraded by the International Olympic Committee and the 1908 Games are seen as the start of the Fourth Olympiad, in keeping with the now-accepted four-year cycle. Overall, 106 events in 24 disciplines were contested.
