Hezex is Kurdish for Idil (Azak or Bet Zabday in Syriac). It is a district in the province of Sirnak in Turkey. The main religion in the area is Islam, even though Idil was once home to the Aramaean people who adhered to the Syriac Orthodox Church -- they spoke the Syriac language, a dialect of Middle Aramaic that was once widely used across Eastern Arabia and the Fertile Crescent. Kayali is one of its most important villages; it is a historically Assyrian importing community near the province of Mardin.
Idil is a part of Tur Abdin (a hilly region in the southeast of Turkey) and was one of the districts which fell victim to the Assyrian Genocide (or seyfo in Syriac, which literally means "the sword" in English) between 1915 and 1918 (the waning years of the Ottoman Empire). After the Assyrian Genocide, many of Idil's (or Hezex) Assyrian population became part of a diaspora. Just like most of the other Armenians, the Assyrian survivors spread out and fled to many countries around the globe, including parts of the Middle East, Canada, Cyprus, Germany, Sweden, and the United States.
