Intangible cultural heritage (ICH)—as opposed to a place's tangible cultural heritage, cultural properties such as historic sites, monuments, and artefacts—comprises manifestations of intellectual wealth such as customs, beliefs, traditions, folklore, language, and knowledge, as expressed in particular through craftsmanship and performance.
Responding to the perceived over-representation of Western Europe among World Heritage Sites, to help valorize cultural diversity, and following on from earlier related measures in Japan (1950) and in South Korea (1962), in 2001, UNESCO made a survey among states and NGOs to try to agree on a definition, and the Convention for the Safeguarding of the Intangible Cultural Heritage was drafted in 2003 for its protection and promotion.
