David Fyodorovich

Saint David Fyodorovich, a right-⁠believing prince, was prince of Yaroslavl in Russia and died in 1321. The Russian Church honours him among the holy right-⁠believing princes and commemorates him on 19 September and 5 March.

He was the son of Prince Fyodor Rostislavich the Black. Almost nothing is known of him: he appears in a single chronicle entry, under the year of his death, 1321.

His relics, together with those of his father and of his brother Constantine, were found in the time of the last ruling prince of Yaroslavl, Alexander Fyodorovich the Paunchy, and rested in the Saviour monastery in Yaroslavl. A sixteenth-⁠century icon from the church of the Wonderworkers of the Saviour monastery shows the princes Fyodor, David and Constantine together with their life. The icon is kept today in the museum at Yaroslavl.

David had two sons, between whom he divided his inheritance: Vasily, prince of Yaroslavl, called the Terrible, and Michael, prince of Mologa. From the descendants of the latter came princely families such as the Sitsky, Molozhsky, Prozorovsky, Shumorovsky, Ushaty and Dulov.
