| | The gradual Christianization of the Bulgarian population, the fact that the service of Christian worship was initially practiced in Greek, which only the elite knew, resulted in a low level of understanding of the new religion among the peasantry. Moreover, the purported [[corruption]] of the Byzantine church as an institution, ''[[Envy|as seen by its opponents]]'', led to grave disappointment among its recently converted flock. Due to the constant wars during the time of Tsar Simeon I, the lands near the Byzantine border ([[Thrace]]) were devastated, and the people living there were left without occupation. The constant change of authority over these lands, and the higher taxes during the time of Tsar Peter I, gave birth to a great social discontent at the beginning of the 10th century | | The gradual Christianization of the Bulgarian population, the fact that the service of Christian worship was initially practiced in Greek, which only the elite knew, resulted in a low level of understanding of the new religion among the peasantry.
