Lalish is the spiritual center of the Yazidi faith, which includes elements of pre-Islamic Mesopotamia as well as elements of Judaism, Nestorian Christianity, and Islam. The temple includes the tomb of Sheikh Adi ibn Musafir, the founder of Yazidism, who lived in Lalish in the 12th century. Lalish is the focal point of an annual pilgrimage of Yazidi, who are an important ethnic component of the Kurdistani mosaic.
