Fomin-Berezuesk

Fomin-Berezuesk was a small Rurikid appanage of Smolensk, centred on Fomin Gorodok on the Vazuza. It split from the Smolensk principality in the first half of the thirteenth century.

Fomin was first recorded in 1371. By the fourteenth century the original domain had split into the Fomin, Berezuy and Rzhev appanages, held by descendants of the same family; the Rzhevsky boyars traced their origin to this line. Lithuania absorbed the Fomin lands in the early fifteenth century.
