Crimean Tatar is written in both Latin and Cyrillic. Historically, the Persian script was also used.
Before 1990s Persian alphabet which was used by the Turks before the introduction of the new Latin-based alphabet was used but since 1990s when Verkhovna Rada of Crimea officially accepted the new Common Turkic-based Latin alphabet, it had been dominant mostly on the internet while the Soviet Cyrillic alphabet remained dominant in printed productions. After the 2014 Russian annexation of Crimea, the Russian government requires the use of Cyrillic script only. In 2021 the Ukrainian government started the switch of Crimean Tatar language to the Latin script.[1]
