An Olympic Congress, also known as IOC Congress is a large gathering of representatives from the different constituencies of the Olympic Movement, organised by the International Olympic Committee (IOC). As detailed in chapter 1, rule 4 of the Olympic Charter, the IOC President is responsible for convening a Congress, presiding over its proceedings and for determining its procedures. Olympic Congresses are not regular events in the IOC's calendar. As the Olympic Charter states, "The Olympic Congress gathers representatives of the constituents of the Olympic Movement, at intervals determined by the IOC".
As the role of an Olympic Congress is consultative, all recommendations from the Congress must be submitted to the IOC Session for formal adoption. The first Olympic Congress was held in Paris, France, in 1894. It was this Congress which founded and established the IOC and laid the groundwork for its statutes. The process of revival of the Olympic Games also began at the Paris Congress of 1894.
