Cizre (pronounced [dʒizˈɾe]; Kurdish: Cizîra Botan or Cizîr) is a town and district of Şırnak Province in the Southeastern Anatolia Region of Turkey, located at the border to Syria, just to the north-west of the Turkish-Syrian-Iraqi tripoint. Cizre is surrounded by the Tigris from the North, East and South, which has given it its name, which means island in Arabic. Its population is predominantly Kurdish.
Cizre is historical Jazīrat ibn ʿUmar (or Jezira ibn Umar or Gazarta) Arabic: ﺟزﯾرة اﺑن ﻋﻣر , an important town during the Abbasid period and the Crusades as a gateway connecting Upper Mesopotamia to Armenia. During the Early Iron Age, Cizre was in the kingdom of Kumme,north of Mesopotamia. In classical antiquity, it was located in Corduene (Kardu). In 19th century scholarship, it was often named as the location of Alexander's crossing of the Tigris in 331 BC, further identified with the Roman stronghold of Bezabde although Stein (1942) is sceptical of this.
In medieval Islamic tradition, it is the location of Thamanin, the town founded by Noah at the foot of Mount Judi where the Ark came to rest, and a "tomb of Noah" as well as a "tomb of Mem and Zin" can be visited in Cizre. Al-Masudi (d. 956) reports that the spot where the ark landed could still be seen in his time. Benjamin of Tudela in the 12th century adds that ʿUmar ibn al-Khaṭṭāb had made the remnants of the ark into a mosque.
In Ottaman Period, Cizre used to be a province including the neighbour towns Idil, Silopi and some neighbour villages in Northearstern Syria. It has always been considered the center of the Kurmanji Kurdish culture. Today the Mayor of the town is Leyla Guveb, from Demokratik Bölgeler Partisi (DBP).
