The international speleological community, mostly Europeans, agreed in a meeting in 1949 in Valence-sur-Rhone, France, to hold international speleological congresses beginning in Paris in 1953. The International Union of Speleology formed in 1965 upon the initiative of the International Speleological Congress in that year.[2]

Its activities take place in a number of commissions and working groups, such as the UIS Informatics Commission formed in 1986, the Speleotherapy Commission and the Karst Hydrogeology and Speleogenesis Commission.[3]


The UIS publishes the International Journal of Speleology.
