The People's Council of Preslav (Bulgarian: Преславски народен събор) took place in 893. It was among the most important events in the history of the First Bulgarian Empire and was a cornerstone of the Christianization of Bulgaria under prince Boris I.
In 889 Boris I abdicated and retired to a monastery and was succeeded by his eldest son Vladimir-Rasate who tried to restore Tengrism, the traditional religion of the country since 681. After Vladimir-Rasate was deposed by his father in 893, the latter gathered a People's Council[a] in Preslav to legitimate the changes.[1][2] Since the issues to be discussed were of great importance for the whole country, the attendance and approval of the higher and lower nobility, the clergy and representatives of all provinces was needed.[3] There is no direct mention of the Council in medieval sources. The most detailed description of the events that led to the downfall of Vladimir-Rasate comes from the Benedictine abbot Regino of Prüm in his work Chronicon:[4]
...The Prince of that people [Boris I], as they say, after accepting the blessing of Baptism, showed such a perfection, that during the day he appeared to his people in kingly garments and during the night, covered in crude clothes entered secretly in the church and lying on the floor of the temple, he spent his time in prayer, putting only sackcloth below. Soon he left the earthly kingdom and after he put into his place as a Prince his eldest son [Vladimir], he tonsured, took the garment of the holy asceticism and became a monk, dedicating his day and night to charity, vigil and prayers. In the meanwhile, his son whom he placed for Prince and who was by far less zealous and active than his father, began to plunder and spend his time in drinking, feasts and debauchery and with all means to turn his newly baptized people back to the pagan rituals. When his father learned that, inflamed by great anger took off his monastic clothes, put again the military sash, put on the royal garments and when he took those who feared God, set against his son. Soon he captured him without much difficulty, pulled out his eyes and sent him in prison. Then he gathered his whole empire and placed for Prince his younger son [Simeon I], and threatened him before everyone with the same punishment if he would betray the true Christianity. After he thus arranged that, he took off the sash, put on the holy monastic clothes and when he went to a monastery, he spend the rest of the time of his present life in holy asceticism
According to the historians the council was presided by Boris I and four major decisions were taken:[1]
The decisions taken during the Council of Preslav had a great impact on Bulgarian history. The official status of Old Bulgarian gave great impetus for the development of the Preslav and Ohrid Literary Schools. The Bulgarian culture and literature entered its Golden Age under the rule of the newly elected Simeon I and the country became the cultural and spiritual center of Slavic Europe.[12] The removal of the Byzantine clergy and the Greek language from the liturgy ensured that Bulgaria would stay away from any strong or direct Byzantine influence in its policy and religious life.[13]
The Byzantine reaction was quick. As soon as 894 emperor Leo VI moved the market of the Bulgarian merchants from Constantinople to Salonica which was a heavy blow to the Bulgarian economic interests.[14] This inflamed the first commercial war in Europe[15] won by Simeon I after the decisive battle of Boulgarophygon.
