Konstantin Davidovich

Konstantin Davidovich (c. 1184–1218) was a Smolensk Rurikid, the younger son of Davyd Rostislavich. When his father died in 1197, he was entrusted to his uncle Rurik Rostislavich in the Kyiv land, who presumably granted him an appanage, though no chronicle names his throne.

Polish chronicles record that he joined a campaign against Lithuania in 1207. He died in 1217 or 1218, and later genealogical tradition makes him ancestor of the princes of Fomin and Berezuysk.
