A report on Cyrillic script and First Bulgarian Empire

Exiled students of the two apostles, mainly Bulgarians (including Clement of Ohrid and Saint Naum), then brought the Glagolitic alphabet to the First Bulgarian Empire.

Both schools originally used the Glagolitic alphabet, though the Cyrillic script developed early on at the Preslav Literary School, where it superseded Glagolitic as official in Bulgaria in 893.

In 886, Clement of Ohrid (also known as Kliment), Naum, Gorazd, Angelar and Sava arrived in the First Bulgarian Empire where they were warmly accepted by the Tsar Boris I of Bulgaria.

Both the Glagolitic and Cyrillic alphabets were used until 13th-14th century in Bulgaria.

In 681, Constantine IV signed a treaty with the Bulgar khan Asparukh, and the new Bulgarian state assumed sovereignty over several Slavic tribes that had previously, at least in name, recognised Byzantine rule.

Cyril and Methodius, two Byzantine Greek brothers from Thessaloniki, contributed significantly to the Christianisation of the Slavs and in the process devised the Glagolitic alphabet, ancestor to the Cyrillic script.

830 – December 23, 910) was a medieval Bulgarian writer, enlightener, one of the Seven Apostles of the First Bulgarian Empire and missionary among the Slavs.

He was among the disciples of Saints Cyril and Methodius and is associated with the creation of the Glagolitic and Cyrillic script.

Tsar Simeon (also Symeon) I the Great (цѣсар҄ь Сѷмеѡ́нъ А҃ Вели́къ цар Симеон I Велики Συμεών Αʹ ὁ Μέγας) ruled over Bulgaria from 893 to 927, during the First Bulgarian Empire.

The newly independent Bulgarian Orthodox Church became the first new patriarchate besides the Pentarchy, and Bulgarian Glagolitic and Cyrillic translations of Christian texts spread all over the Slavic world of the time.

They fled to the First Bulgarian Empire, where they were welcomed and commissioned to establish theological schools.

There they and scholar Saint Clement of Ohrid devised the Cyrillic script on the basis of the Glagolitic.

Saint Clement of Ohrid (Bulgarian, Serbian and Macedonian: Свети Климент Охридски, ; Ἅγιος Κλήμης τῆς Ἀχρίδας; svätý Kliment Ochridský; c. 830-840 – 916) was one of the first medieval Bulgarian saints, scholar, writer and enlightener of the Slavs.

He was one of the most prominent disciples of Saints Cyril and Methodius and is often associated with the creation of the Glagolitic and Cyrillic scripts, especially their popularisation among Christianised Slavs.

After the Christianisation of Bulgaria in 864, the disciples of Cyril and Methodius in Bulgaria, the most important being Clement of Ohrid and Naum of Preslav, were of great importance to the Orthodox faith in the First Bulgarian Empire.

A major event in this effort was the development of the Cyrillic script in Bulgaria, at the Preslav Literary School in the ninth century; this script, along with the liturgical Old Church Slavonic, also called Old Bulgarian, were declared official in Bulgaria in 893.

The Preslav Literary School (Преславска книжовна школа), also known as the Pliska Literary School or Pliska-Preslav Literary school was the first literary school in the medieval Bulgarian Empire.

The school developed the Cyrillic script:

The Early Cyrillic alphabet, also called classical Cyrillic or paleo-Cyrillic, is a writing system that was developed in the First Bulgarian Empire during the late 9th century on the basis of the Greek alphabet for the Slavic people living near the Byzantine Empire in South East and Central Europe.

The modern Cyrillic script is still used primarily for some Slavic languages (such as Bulgarian, Macedonian, Serbian, Russian and Ukrainian), and for East European and Asian languages that have experienced a great amount of Russian cultural influence.
