Cyrillic script

The Cyrillic script (/sɪˈrɪlɪk/ ^ⓘ sih-RI-lik) is a writing system used for various languages across Eurasia. It is the designated national script in various Slavic, Turkic, Mongolic, Uralic, Caucasian and Iranic-speaking countries in Southeastern Europe, Eastern Europe, the Caucasus, Central Asia, North Asia, and East Asia, and used by many other minority languages.

As of 2019^[update], around 250 million people in Eurasia use Cyrillic as the official script for their national languages, with Russia accounting for about half of them. With the accession of Bulgaria to the European Union on 1 January 2007, Cyrillic became the third official script of the European Union, following the Latin and Greek alphabets.

The Early Cyrillic alphabet was developed during the 9th century AD at the Preslav Literary School in the First Bulgarian Empire during the reign of Tsar Simeon I the Great, probably by the disciples of the two Byzantine brothers Cyril and Methodius, who had previously created the Glagolitic script. Among them were Clement of Ohrid, Naum of Preslav, Constantine of Preslav, Joan Ekzarh, Chernorizets Hrabar, Angelar, Sava and other scholars. The script is named in honor of Saint Cyril.

Since the script was conceived and popularised by the followers of Cyril and Methodius in Bulgaria, rather than by Cyril and Methodius themselves, its name denotes homage rather than authorship.

The Cyrillic script was created during the First Bulgarian Empire. Modern scholars believe that the Early Cyrillic alphabet was created at the Preslav Literary School, the most important early literary and cultural center of the First Bulgarian Empire and of all Slavs:

Unlike the Churchmen in Ohrid, Preslav scholars were much more dependent upon Greek models and quickly abandoned the Glagolitic scripts in favor of an adaptation of the Greek uncial to the needs of Slavic, which is now known as the Cyrillic alphabet.

A number of prominent Bulgarian writers and scholars worked at the school, including Naum of Preslav until 893; Constantine of Preslav; Joan Ekzarh (also transcr. John the Exarch); and Chernorizets Hrabar, among others. The school was also a center of translation, mostly of Byzantine authors. The Cyrillic script is derived from the Greek uncial script letters, augmented by ligatures and consonants from the older Glagolitic alphabet for sounds not found in Greek. Glagolitic and Cyrillic were formalized by the Byzantine Saints Cyril and Methodius and their Bulgarian disciples, such as Saints Naum, Clement, Angelar, and Sava. They spread and taught Christianity in the whole of Bulgaria. Paul Cubberley posits that although Cyril may have codified and expanded Glagolitic, it was his students in the First Bulgarian Empire under Tsar Simeon the Great that developed Cyrillic from the Greek letters in the 890s as a more suitable script for church books.

Cyrillic spread among other Slavic peoples, within the First Bulgarian Empire (which encompassed modern day Romania, Serbia and parts of Ukraine) and beyond. The earliest datable Cyrillic inscriptions have been found in the area of Preslav, in the medieval city itself and at nearby Patleina Monastery, both in present-day Shumen Province, as well as in the Ravna Monastery and in the Varna Monastery. The new script became the basis of alphabets used in various languages in Orthodox Church-dominated Eastern Europe, both Slavic and non-Slavic languages. For centuries, Cyrillic was also used by Catholic and Muslim Slavs.
