Description Available in: The Palestine Police Force was a British colonial police service established in Mandatory Palestine on 1 July 1920, when High Commissioner Sir Herbert Samuel's civil administration took over responsibility for security from General Allenby's Occupied Enemy Territory Administration (South). The police force was composed of Jewish, Arab and British officers. However, over the course of the Mandate, the police force became less representative of Palestinian populations and increasingly functioned to repress Palestinian political mobilization and to facilitate the establishment of a homeland for the Jewish people.
