Cyrillic Script - History

History

The Cyrillic script was created in the First Bulgarian Empire and is derived from the Greek uncial script letters, augmented by ligatures and consonants from the older Glagolitic alphabet for sounds not found in Greek. Tradition holds that Cyrillic and Glagolitic were formalized either by the two Greek brothers born in Thessaloniki, Saints Cyril and Methodius who brought Christianity to the southern Slavs, or by their disciples. Paul Cubberley posits that while Cyril may have codified and expanded Glagolitic, it was his students in the First Bulgarian Empire that developed Cyrillic from the Greek letters in the 890s as a more suitable script for church books. Later Cyrillic spread among other Slavic peoples: Russians, Serbs and others, as well as among non-Slavic Vlachs and Moldavians.

Cyrillic and Glagolitic were used for the Church Slavonic language, especially the Old Church Slavonic variant. Hence expressions such as "И is the tenth Cyrillic letter" typically refer to the order of the Church Slavonic alphabet; not every Cyrillic alphabet uses every letter available in the script.
