Demetrius of Chernigov

Holy Right-⁠believing Demetrius of Chernigov was a prince's son of Chernigov and died on 1 April 1223, in the battle at the river Kalka against the Tatars. He is commemorated on 1 April, by the old calendar.

Archimandrite Leonid, in "Holy Russia", writes of Demetrius Mstislavich, son of Grand Prince Mstislav, killed on the Kalka in 1223 and buried in the cathedral of Chernigov. The menologion of Dimitry Sambikin supposes that he was a son of Grand Prince Mstislav III Romanovich, although among that prince's sons there is none named Demetrius; it may have been a baptismal name of one of them. The burial in Chernigov points rather to a link with the family of the princes of Chernigov than with that of the grand princes of Kyiv.
