Pearson, assistant political officer at Zakho, by Kurds on 4 April 1919, the occupation of Jazirat Ibn ʿUmar was considered to ensure the security of British Iraq, but ultimately dismissed. Ahmed Hilmi, Mufti of Jazirat Ibn ʿUmar, was ordered to be arrested in May 1919 for his role in the massacre in 1915 as part of the Turkish courts-martial of 1919–1920, but he evaded arrest as he was under the protection of local Kurdish clans. Appeals from Kurds to the British government to create an independent Kurdish state spurred the appointment of Nihat Anılmış as commander at Cizre in June 1920 with instructions from the Prime Minister of Turkey Mustafa Kemal to establish local government and secure control of local Kurds by inciting them to engage in armed clashes against British and French forces, thus preventing good relations.

In response to Kurdish revolts in the 1920s, the Turkish government aimed to Turkify the population of eastern Turkey, but Christians were deemed unsuitable, and thus attempted to eradicate those who had survived the genocide. In this effort, 257 Syriac Orthodox men from Azakh and neighbouring villages were imprisoned by the government at Cizre in 1926, where they were beaten and denied food. Late 20th century and contemporary period Cizre received electricity and running water in the mid-1950s. In the 1960s, the infrastructure of the city was developed as a new bridge, municipal buildings, and new roads were constructed and streets were widened, and amenities such as a public park named after Atatürk and a cinema were built. Roughly 60 people were detained and tortured for 20 days by Turkish police after the killing of two Turkish policemen in Cizre on 13 January 1989. The economy of Cizre
