Wayang also known as Wajang, is a form of puppet theatre art found in Indonesia and other parts of Southeast Asia, wherein a dramatic story is told through shadows thrown by puppets and sometimes combined with human characters. The art form celebrates the Indonesian culture and artistic talent; its origins are traced to the spread of Hinduism in the medieval era and the arrival of leather-based puppet arts called Tholu bommalata from southern India.
UNESCO designated wayang kulit, a shadow puppet theatre and the best known of the Indonesian wayang, as a Masterpiece of Oral and Intangible Heritage of Humanity on 7 November 2003. In return for the acknowledgment, UNESCO required Indonesians to preserve their heritage. Wayang has also been a significant historical art form in Malaysia, Thailand, Cambodia and Laos.
