Multiculturalism in the Sinjar region is rooted in the beginnings of Yazidis itself. An example to this is the architecture, i.e. the typical squared plan building, covered by a dome raised on a squared or octagonal drum. The form of the dome is influenced by the Shiite architecture of Mosul of the 13th century, when the city was the artistic centre at the time of Badr al-Din Lulu (1211-1259), the Atabeg of Mosul. These influences reconnect to the Shiite architecture of the mausolea of Mosul and Sinjar (Açıkyıldız 2009: 110).
From sources dated to the 20th century we know that the population of Sinjar was composed by Muslim Kurds, Sunnis, Shias, besides Yazidis, with tribes mainly Sunni and Christians living among settled people (Fuccaro 1994: 39). This is to say that Sinjar region has always been inhabited by different religious groups, which sometimes shared beliefs, practices and cultural themes, independently of their religious beliefs (Fuccaro 1994: 112), and moreover all tribes were integrated and not discriminated on the basis of their religious belief (Fuccaro 1994: 113).
