The twelfth Olympic congress was held in Paris in 1994, on the occasion of the centenary of the modern games. The congress is there to decide upon the main issues concerning the Olympic movement, such as ethics, professionalism, doping, etc...The congress is made up of the I.O.C. members, the presidents of the national committees, the presidents of the sporting federations, and the organisation committee for the coming games. Today, the Olympic congress meets regularly, every eight years. It should be noted that from 1894 to 1933 the Olympic congress was held at regular intervals, but remained inactive for the following forty years, until the 1973 Varna summit in Bulgaria.
