^ A: The IOC site for the 1900 Olympic Games gives erroneous figure of 95 events, while the IOC database for the 1900 Olympic Games lists 85. Probably this discrepancy in IOC data is consequence that the figure 95 just derived from the "1900 Olympic Games — Analysis and Summaries" publication of Bill Mallon, who used his own determination of which sports and events should be considered as Olympic.
^ B: The IOC site for the 1904 Olympic Games gives erroneous figure of 91 events, while the IOC database for the 1904 Olympic Games lists 94. Probably this discrepancy in IOC data is consequence that the figure 91 just derived from the "1904 Olympic Games — Analysis and Summaries" publication of Bill Mallon, who used his own determination of which sports and events should be considered as Olympic.
^ C: The IOC site for the 1920 Olympic Games gives erroneous figure of 154 events, while the IOC database for the 1920 Olympic Games lists 156.
^ D: Owing to Australian quarantine laws, 6 equestrian events were held in Stockholm several months before the rest of the 1956 Games in Melbourne, 5 nations from 72 competed in the equestrian events in Stockholm, but did not attend the Games in Melbourne.
^ E: The IOC site for the 1956 Olympic Games gives total of 151 events (145 events in Melbourne and 6 equestrian events in Stockholm).
Note: Although the Games of 1916, 1940, and 1944 had been cancelled, the Roman numerals for those Games were still used because the Summer Games' official titles count Olympiads, not the Games themselves, per the Olympic Charter. This contrasts with the Winter Olympic Games, which ignore the cancelled Winter Games of 1940 & 1944 in their numeric count.
The 1896 Summer Olympics (Greek: Θερινοί Ολυμπιακοί Αγώνες 1896, translit. Therinoí Olympiakoí Agónes 1896), officially known as the Games of the I Olympiad, was the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by Pierre de Coubertin, it was held in Athens, Greece, from 6 to 15 April 1896.
Winners were given a silver medal, while runners-up received a copper medal. Retroactively, the IOC has converted these to gold and silver, and awarded bronze medals to third placed athletes. Ten of the 14 participating nations earned medals. The United States won the most gold medals, 11, host nation Greece won the most medals overall, 46. The highlight for the Greeks was the marathon victory by their compatriot Spyridon Louis. The most successful competitor was German wrestler and gymnast Carl Schuhmann, who won four events.
Athens had been unanimously chosen to stage the inaugural modern Games during a congress organised by Coubertin in Paris on 23 June 1894, during which the IOC was also created, because Greece was the birthplace of the Ancient Olympic Games. The main venue was the Panathenaic Stadium, where athletics and wrestling took place; other venues included the Neo Phaliron Velodrome for cycling, and the Zappeion for fencing. The opening ceremony was held in the Panathenaic Stadium on 6 April, during which most of the competing ath
