Background and evolution

The idea of shared world heritage grew from campaigns such as the international effort in the 1960s to save the Abu Simbel temples in Egypt from the waters of the Aswan High Dam. Conservation movements also pushed for protecting natural areas, and the two strands came together in the Convention Concerning the Protection of the World Cultural and Natural Heritage, adopted in 1972. It entered into force in 1975 and is now one of the most widely ratified international treaties.

Under it, each country nominates sites from a Tentative List it maintains. Advisory bodies evaluate them: ICOMOS for cultural sites, IUCN for natural sites and ICCROM for conservation training and advice. The World Heritage Committee then decides whether to inscribe, refer back, defer or reject a nomination at its annual session.
