The stadium hosted Olympics in 1870 and 1875.[35] Thirty thousand spectators attended that Games in 1870, though no official attendance records are available for the 1875 Games.[36] In 1890, after attending the Olympian Games of the Wenlock Olympian Society, Baron Pierre de Coubertin was inspired to found the International Olympic Committee (IOC).[37] Coubertin built on the ideas and work of Brookes and Zappas with the aim of establishing internationally rotating Olympic Games that would occur every four years.[37] He presented these ideas during the first Olympic Congress of the newly created International Olympic Committee. This meeting was held from 16 to 23 June 1894, at the University of Paris.
