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. 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. 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. This inflamed the first commercial war in Europe won by Simeon I after the decisive
battle of Boulgarophygon. ==Notes==
