The first meeting of the Congrès was held in London and Oxford in 1934 (see A62). There after the intention was to hold it every four years. Following the second meeting in 1938 the third, due in 1942 could not be held, was then to be held in 1947 in Prague but the invitation was withdrawn. The third meeting finally took place in 1948 in Brussels and Tervuren and has been held subsequently every four years as originally planned. See also A93, Conseil Permanent.
