"First initiated by Robert Jungk in 1964 at the inaugural congress of the International Confederation for Disarmament and Peace. Subsequently formed as an international committee in London and as an educational trust in the Netherlands in 1966. Mankind 2000 was reformed in November 1972 and registered under Belgian law on 5th April 1973 as an independent transnational association of cultural, scientific and educational character without profit motive.
The first Mankind 2000 international committee was formed in London in November 1965 following promotional efforts undertaken by the International Confederation for Disarmament and Peace (ICDP) on the basis of an original proposal received from Robert Jungk at the ICDP inaugural conference in 1964.
In September 1967 Mankind 2000 was responsible for convening the International Futures Research Inaugural Conference in the vicinity of Oslo. In addition to the subsequent publication of a book containing a selection of the papers contributed to the conference (edited by Johan Galtung and Robert Jungk : Mankind 2000. London, Allen and Unwin, 1969).
This meeting proved to be the forerunner of further international futures conferences held in Kyoto (1970), Bucharest (1972), Rome (Frascati 1973) and Dubrovnik (1976). Mankind 2000 continued to play a seminal role in the initiation of both the Kyoto and Rome conferences and with the early development of the international futures research movement, notably the World Futures Studies Federation. The prime instigator of these initiatives was James WeIlesley-Wesley who became the first Executive Director of Mankind 2000..
"From 1972, as noted below, it engaged in a strategic initiative, effectively a Union of Intelligible Associations, in partnership with the Union of International Associations. This partnership gave rise to a succession of editions of the Yearbook of World Problems and Human Potential (later titled as the Encyclopedia of World Problems and Human Potential) and its current online variant. From this initiative subsequently emerged the Union of Imaginative Associations and three other complementary bodies. Although effectively dormant, Mankind 2000 holds 50% copyright in the Encyclopedia on the basis of the agreement dating from 1972 and the investment subsequrnly made on its behalf in that initiative.
