Inscribed on UNESCO‘s List of the Intangible Cultural Heritage of Humanity in 2010, Ta’zieh is the updated version of traditional Persian theater which dates back to the pre-Islamic era when Iranians performed passion plays while mourning for Siavash (a 3rd millennium BC mythical Persian prince who also unjustly was killed). The practice of this type of theaters has continued up to now. However, they merged with the religious symbolism granted to their culture by the rise of Islam.
