Semeiskie

The Semeiskie are a community of orthodox Old Believers who have lived in the Transbaikal since the reign of Catherine the Great.

[1] The sacred rites and rituals of the Old Believers came to be in opposition to those of the official state church after the introduction of the 17th century religious reforms known as the Raskol.

The Semeiskie were a particular group of Old Believers who fled to Gomel in Belarus (at that time part of Poland).

[1] Catherine the Great then exiled the group to Buryatia, on the pretext that they could there become farmers for the Cossack guards who defended the borders of the empire.

The Semeiskie songs are notable for their polyphonic dissonance[3] in both sacred and secular music.
