Romanian Cyrillic alphabet
The Romanian Cyrillic alphabet is the Cyrillic alphabet that was used to write the Romanian language and Church Slavonic as early as the 14th century, and used until the early 1860s, when it began to be gradually replaced by a Latin-based Romanian alphabet. Cyrillic remained in occasional use until the 1920s, mostly in Russian-ruled Bessarabia.
