Like all Turkic languages in Central Asia, Uzbek was written in various forms of the Arabic script such as "Yana imla" by the literate population. Between 1928 and 1940, as part of comprehensive programmes to educate (and politically influence) Uzbek people, who for the first time now had their own cartographically delineated (administrative) region, Uzbek writing was switched to Latin script (Yanalif; a proposal for the latinization of Yana imla was already developed in 1924). The Latinization of Uzbek was carried out in the context of Latinization of all Turkic languages.
