IUCN was founded in which year?
International Union for Conservation of Nature was constituted on 5 October 1948 at Fontainebleau near Paris following an international congress sponsored by UNESCO and French government with Julian Huxley as driving force. Initially named International Union for Protection of Nature IUPN, it represented first global alliance of governments, NGOs, and scientists dedicated to nature protection. Establishment responded to post-war recognition of habitat destruction and need for data-driven conservation. Today IUCN hosts World Conservation Congress every four years. This pattern is frequently tested in NCERT-based competitive examinations requiring precise recall of taxonomic hierarchy principles.
