Latinisation in the Soviet Union
Latinisation or latinization (Russian: латиниза́ция, romanized: latinizatsiya [ɫətʲɪnʲɪˈzat͡sɨjə]) was a campaign in the Soviet Union to adopt the Latin script during the 1920s and 1930s. Latinisation aimed to replace Cyrillic and traditional writing systems for all languages of the Soviet Union with Latin or Latin-based systems, or introduce them for languages that did not have a writing system.
