Concept
Boris I of Bulgaria
Summary
Boris I (also Bogoris), venerated as Saint Tsar Boris I (Mihail) the Baptizer (Борисъ А҃ / Борисъ-Михаилъ Борис I / Борис-Михаил; died 2 May 907), was the ruler of the First Bulgarian Empire in 852–889. The historian Steven Runciman called him one of the greatest persons in history. Despite a number of military setbacks, the reign of Boris I was marked with significant events that shaped Bulgarian and European history. With the Christianization of Bulgaria in 864, paganism (i.e. Tengrism) was abolished. A skillful diplomat, Boris I successfully exploited the conflict between the Patriarchate of Constantinople and the Papacy to secure an autocephalous Bulgarian Church, thus dealing with the nobility's concerns about Byzantine interference in Bulgaria's internal affairs.
When in 885 the disciples of Saints Cyril and Methodius were banished from Great Moravia, Boris I gave them refuge and provided assistance which saved the Glagolithic and later promoted the development of the Cyrillic script in Preslav and the Slavic literature. After he abdicated in 889, his eldest son and successor tried to restore the old pagan religion but was deposed by Boris I. During the Council of Preslav which followed that event, the Byzantine clergy was replaced with Bulgarian, and the Greek language was replaced with what is now known as Old Church Slavonic.
He is regarded as a saint in the Orthodox Church, as the Prince and baptizer of Bulgaria, and as Equal-to-the-Apostles, with his feast day observed on May 2 and in Synaxis of all venerable and holy Fathers of Bulgaria (movable holiday on the 2nd Sunday of Pentecost).
The most common theory is that the name Boris is of Bulgar origin. After his official act of conversion to Christianity, Boris adopted the Christian name Michael. He is sometimes called Boris-Michael in historical research.
The only direct evidence of Boris's title are his seals and the inscription found near the town of Ballsh, modern Albania, and at Varna.
