The ICF was initially formed in 1966 as a committee of the Royal Caledonian Curling Club in Perth after the success of the Scotch Cup series of world championships held between Canada and Scotland. At the outset, it comprised the associations of Scotland, Canada, Sweden, Norway, Switzerland, and the United States. In the wake of its formation, it sanctioned the World Curling Championships. The WCF currently sanctions fifteen international curling events (see below). The WCF is managed by eight Board Directors, one president, three vice-presidents (one from each WCF regional zone - Americas, Europe, Pacific-Asia) and six Board Directors. The six Board Directors must all come from different member associations. All positions on the Board of Directors are elected by WCF member associations. The Board of Directors are supported by and a permanent staff of 20 employees.
