The Azerbaijani alphabet (Azerbaijani: Azərbaycan əlifbası, آذربایجان الفباسی) has two versions.
North Azerbaijani, the official language of Republic of Azerbaijan, is written in a modified Latin alphabet. This superseded previous versions based on Cyrillic and Persian/Arabic scripts after the fall of Soviet Union and independence of Azerbaijan.
In Iran, where Azeri people make up the second largest ethnic group after Persians, a modified Persian script is widely used to write the South Azerbaijani language.
Azeris in Dagestan still use the Cyrillic script.[1]
