Mosul vilayet
The Mosul Vilayet was a first-level administrative division of the Ottoman Empire. It was created from the northern sanjaks of the Baghdad Vilayet in 1878. Mosul Vilayet was part of 'the Iraq Region'.
At the beginning of the 20th century, it reportedly had an area of, while the preliminary results of the first Ottoman census of 1885 gave the population as 300,280. The accuracy of the population figures ranges from "approximate" to "merely conjectural" depending on the region from which they were gathered.
The city of Mosul and the area south to the Little Zab was allocated to France in the 1916 Sykes-Picot Agreement of the First World War, and later transferred to Mandatory Iraq following the Mosul Question.
Administrative divisions
In official Ottoman correspondence, the Mosul Vilayet was considered part of 'the Iraq region', a term that collectively referred to the provinces of Mosul, Baghdad, and Basra. Ottoman officials used this designation in administrative and military documents to emphasize the interconnected nature of these three provinces, which were regarded as forming the core of Ottoman Iraq. This regional framework, which predated the Sykes-Picot Agreement, reflected the Ottoman state's view of Iraq as a coherent and administratively linked zone within the empire. Initially subordinate to the Baghdad Vilayet, Mosul was separated and elevated to vilayet status in 1878, a change that weakened administrative cohesion in the region. The separation reflected broader Ottoman efforts to manage the security and tribal dynamics of Northern Mesopotamia, where frequent uprisings and external pressures from Qajar Persia and Britain made centralized control increasingly difficult.Sanjaks of the vilayet and their capitals:
