Clement of Ohrid was a 9th-century scholar, writer, and archbishop who lived during the First Bulgarian Empire. As a prominent disciple of Cyril and Methodius, he played a vital role in spreading Slavic literacy and Christian teachings. He is widely credited with helping popularize the Glagolitic and Cyrillic scripts among Slavic populations. By establishing the Ohrid Literary School, he educated thousands of students in the Old Church Slavonic language, which helped preserve the distinct cultural identity of the Slavic people in the region.
