Who Invented Cyrillic? Cyril, His Disciples and the Evidence
| Candidate | Case for | Case against |
|---|---|---|
| Saint Cyril | The script bears his name | He created Glagolitic; he died in 869, decades before the first Cyrillic texts |
| Clement of Ohrid | Traditionally credited; a leading disciple | The Ohrid school kept using Glagolitic for centuries |
| Preslav Literary School (Naum, Constantine of Preslav, John the Exarch and others) | Earliest Cyrillic finds are from the Preslav area | No source names a single author |
| Gradual development | Greek letters were already used to write Slavic | Someone still had to systematize it |
Who invented Cyrillic has no single-name answer. Saint Cyril created the earlier Glagolitic alphabet, not Cyrillic. Cyrillic was developed in the late 9th or early 10th century in the First Bulgarian Empire, most likely at the Preslav Literary School, by disciples of Cyril and Methodius. Clement of Ohrid is traditionally credited, but most scholars favor the Preslav circle.
Who invented Cyrillic is one of the most common questions about the alphabet, and the honest answer is: nobody knows the exact person. What scholars agree on is that Saint Cyril did not invent it, despite the name. It was created a generation after him, in the First Bulgarian Empire, by people trained in his tradition.
The short answer: not Saint Cyril
Saint Cyril (born Constantine) and his brother Methodius began their mission to Great Moravia in 863. For it, Cyril created a script, but that script was the Glagolitic alphabet, with its distinctive loops and crosses.
Cyril died in Rome in 869. The earliest dated Cyrillic inscription, from Krepcha in northeastern Bulgaria, is from 921, half a century later. Britannica and most modern reference works say the same: Cyrillic was devised by Cyril’s followers, and its name is an homage to him rather than a record of authorship.
In Bulgarian the two scripts are глаголица (glagolitsa) and кирилица (kirilitsa). Medieval Bulgarian writers wrote about “Slavic letters” in general and never named a separate creator for the second script, which is part of why the authorship question is so hard to settle.
Who invented Cyrillic: the main candidates
After Methodius died in 885, his disciples were driven out of Moravia. Prince Boris I welcomed them to Bulgaria around 886. Two schools grew from that move, and the debate about Cyrillic’s origin mostly comes down to them.
Clement of Ohrid
Clement is the name most often linked to Cyrillic. He was one of the senior disciples and taught at Ohrid from 886 to 893, where a later biography credits him with some 3,500 students. Many popular sources say he created Cyrillic.
The problem is that the Ohrid school kept writing in Glagolitic, into the 12th century. Many scholars therefore see Clement as a great teacher and writer of Slavic texts, but not as the most likely creator of the new script. Wikipedia sums up the current view: the invention is “usually ascribed” to Clement, but Cyrillic was most likely developed at Preslav.
The Preslav Literary School
Preslav became Bulgaria’s capital in 893. Its literary school, supported by Tsar Simeon I, gathered scholars such as Naum of Preslav, Constantine of Preslav, John the Exarch and the monk known as Chernorizets Hrabar.
Several things point here. The earliest dated Cyrillic texts come from the Preslav area, including the Krepcha inscription (921) and a ceramic vessel from Preslav (931). The Preslav school also moved quickly from Glagolitic to a script based on Greek capitals. Many scholars think Cyrillic was the work of this circle rather than of one person.
Some historians link the new script to the Council of Preslav in 893, which made Slavic the language of church and state in Bulgaria. That would have been a natural moment to systematize a new alphabet, but no medieval source says so directly.
A gradual development
A third view, associated with the American Slavist Horace Lunt, is that Slavs in areas close to Greek missions were already writing their language in Greek letters. A Slavic scholar then standardized that practice by adding letters for Slavic sounds. In this view, Preslav codified Cyrillic rather than inventing it from nothing.
How Cyrillic was built
Whoever designed it, the method is clear from the letters. The core of the Cyrillic alphabet is Greek uncial script, the rounded capitals of 9th- and 10th-century Greek books. Letters such as А, В, Г, Д, Е, К, М, О, П, Р, С and Т follow Greek models.
Greek had no letters for some Slavic sounds, so the designers took or adapted Glagolitic letters. Ж, Ц, Ч, Ш, Щ, Ъ and Ь are traced to Glagolitic models. That borrowing is one reason scholars are confident Glagolitic came first.
The choice of Greek letters also made sense politically. Bulgaria’s elite and clergy knew Greek writing, and a Greek-looking script fit the Byzantine church world Bulgaria belonged to.
What medieval writers said
No medieval text names the inventor of Cyrillic. The Bulgarian treatise On the Letters by Chernorizets Hrabar, written in the late 9th or early 10th century, defends Slavic writing and credits Constantine (Cyril) with creating 38 letters. Scholars mostly read it as a defense of Slavic letters against Greek critics. Some think it may instead defend Glagolitic against the newer Cyrillic, which would show that the two scripts were competing at Preslav.
One later account sometimes cited is the biography of Clement by Theophylact of Ohrid, written around 1100, which praises Clement’s work on Slavic letters. How much weight to give it is debated, since it was written two centuries after the events.
Why the question still matters
The debate is mostly about evidence, but it also touches national pride. Bulgaria celebrates Cyrillic as a Bulgarian creation, and the Preslav origin supports that. North Macedonia honors Clement and Ohrid. Both traditions are part of the same story, and the evidence suggests both schools mattered: Ohrid preserved Glagolitic learning, and Preslav produced Cyrillic. See Bulgarian alphabet history for the full timeline.
Common mistakes
- “Cyril and Methodius invented Cyrillic.” They created Glagolitic. Cyrillic was named after Cyril by later followers.
- “Cyrillic was invented in Russia.” It was developed in the First Bulgarian Empire and reached Rus with church books.
- “Clement of Ohrid definitely invented it.” He is the traditional candidate, but the evidence points more strongly to Preslav.
- “Cyrillic came before Glagolitic.” Some 19th-century scholars argued this, but Cyrillic’s borrowed Glagolitic letters show Glagolitic is older.

Frequently asked questions
Who invented Cyrillic?
No single inventor is known. Cyrillic was developed in the late 9th or early 10th century in the First Bulgarian Empire, most likely at the Preslav Literary School, by disciples of Saints Cyril and Methodius.
Did Saint Cyril invent the Cyrillic alphabet?
No. Cyril created the Glagolitic alphabet around 863. Cyrillic was developed after his death in 869 and named in his honor.
Did Clement of Ohrid create Cyrillic?
He is traditionally credited, but many scholars doubt it because his Ohrid school kept using Glagolitic. Most now place Cyrillic’s origin at Preslav.
Where was Cyrillic invented?
In the First Bulgarian Empire. The earliest dated Cyrillic inscriptions, from 921 and 931, come from northeastern Bulgaria near the capital Preslav.
Why is it called Cyrillic if Cyril did not invent it?
The name honors Cyril as the creator of the first Slavic script and the founder of Slavic literacy. It is a tribute, not a statement of authorship.
