The International Ski Federation arranged annual Rendezvous races from 1925 to 1927 and annual FIS races from 1929 to 1935. At the FIS congress in 1936, it was decided that the first World Championships should be held in 1937 and take place in Chamonix, France. All Rendezvous and FIS races were given official World Championship status at FIS' 25th congress in 1965. This decision meant that the FIS Nordic World Ski Championships 1925 in Janské Lázně, Czechoslovakia, were given status as the first official World Championships.
