The districts of Mandatory Palestine formed the first level of administrative division and existed through the whole era of Mandatory Palestine, namely from 1920 to 1948. The number and territorial extent of them varied over time, as did their subdivision into sub-districts. In Arabic, a district was known as a minṭaqah (منطقة, plural manaṭiq مناطق), while in Hebrew it was known as a mahoz (מחוז, plural mehozot מחוזות). Each district had an administration headed by a District Governor, a role renamed as District Commissioner in 1925.
