Zor Sanjak

The Sanjak of Zor () was a sanjak of the Ottoman Empire, which was created in 1857. Some of its area was separated from the Baghdad Vilayet. Zor was sometimes mentioned as being part of the Aleppo Vilayet, or of the Syria Vilayet.
The capital was Deir Ez-Zor, a town on the right (i.e., south) bank of the Euphrates, which was also the only considerable town of the sanjak. At the beginning of the 20th century, the sanjak had an area of , and an estimated population of 100,000, mostly Arab nomads. The capital itself was just a village before becoming the centre of the sanjak.
After the fall of the Ottoman Empire in 1918, Ottoman forces withdrew from the area leaving a no man's land. The region was subsequently occupied by Iraqi nationalists representing the Arab Kingdom of Syria in Damascus, and after the Paulet–Newcombe Agreement in 1923, it became part of the French Mandate for Syria.
