Fyodor Konstantinovich Krasny

Fyodor Krasny, called the Red, was born around 1300 as the eldest son of Prince Konstantin Yuryevich of Fomin, and ruled the Rurikid appanages of Fomin and Berezuysk jointly with his brothers. The chronicles name him as a commander in Ivan Kalita's 1340 campaign against Smolensk.

In late 1345 he married Yevpraksia, widow of the Muscovite grand prince Simeon the Proud. Genealogies credit him with four sons, ancestors of several Muscovite serving clans. He died in old age in Moscow on 5 March 1387, taking the monastic name Simeon.
