in Bulgaria, welcomed the disciples of Cyril and Methodius. Bulgaria was ruled then by Tsar Boris, who converted to Christianity in 864. After the christianization the religious ceremonies were conducted in Greek by a Byzantine clergy. Fearing growing Byzantine influence Boris viewed the adoption of the Old Church Slavonic as a way to preserve the political independence of Bulgaria. With such views, Boris made arrangements for the establishment of two literary academies where theology was to be taught in the Slavonic language. The first of the schools was founded in the capital, Pliska, and the second in Ohrid, in the region of Kutmichevitsa. The development of Old Church Slavonic literacy had the effect of preventing the assimilation into the neighboring cultures and promoted the formation of a distinct Bulgarian identity. Naum moved initially to the capital Pliska together with Clement, Angelarius and possibly Gorazd (according to other sources, Gorazd was already dead by that time). In Bulgaria, he spent the next 25 years of his life. Naum was one of the founders of the Pliska Literary School where he worked between 886 and 893. The most reliable first-hand account of the activities at the time in Pliska is "An Account of Letters" (O pismenech), a treatise on Slavic literacy written in Old Church Slavonic, thought to be composed shortly after 893. The piece calls for the creation of a common Slavic alphabet. In 893, shortly after his rise to power, the new Bulgarian ruler Simeon the Great, summoned an ecclesiastical council in the new capital Preslav, where Clement was ordained bishop of Drembica and Velika. To replace Clement in Ohrid, Simeon sent Naum, who until then had been active in Preslav. Afterwards, Naum continued Clement's work at Ohrid, another important centre of Slavic learning. In these years the Cyrillic script was created in the Preslav literary school, and was adopted in Bulgaria, possibly following Naum's initiative. In 905 Naum founded a monastery on the shores of Lake Ohrid, which later received his name. He died there in 910 and Clement initiated the process of his canonization. In this way Naum became the first “native” saint of Bulgaria. Cult The cults towards saint Naum revered particularly in the region of Ohrid. It spread in the first half of the 18th century with the development of Moscopole as a center of Orthodox culture and with the development of the Archbishopric of Ohrid.
