Bogomilism

Bogomilism was a Gnostic religiopolitical sect founded in the First Bulgarian Empire by the priest Bogomil during the reign of Tsar Petar I in the 10th century. It most probably arose in what is today the region of Macedonia as a response to the social stratification that occurred as a result of the introduction of feudalism and as a form of political movement and opposition to the Bulgarian state and the church.
