There were many changes in the administrative system in Iraq from the late Ottoman era until the British occupation in the years (1914-1918) in the formation of administrative units and their abolition as a result of the weakness of the Ottoman Empire in the late twentieth century on the one hand, and British policy on the other hand. Despite the creation of a Al-Mawali (Al-Humaydat itself) at the end of the Ottoman era in 1899, but it was quickly abolished and its districts were linked to the Mosul district in 1905, This continued until the British control of Mosul in1918, when the British authorities divided Mosul, after taking control of it in1918, into the right-side areas. On the left side, Al-Mawali district was re-established as Al-Humaidat district within the areas of the right side, It witnessed administrative instability, as the British authorities attached it to the Tal Afar District after its creation in 1919, but after the establishment of the modern Iraqi state in 1921, it was attached to the Mosul District during the period (1928-1933), and this continued until the year 1956, after the creation of the Shura District, so it was attached to it. After that, it was separated from the Shura District and annexed to the Mosul District in 1962. It continued as it was until it was abolished in 1987, and all its districts were annexed to the Mosul District.
