Mstislav

Mstislav Andreyevich was the second son of Great Prince Andrey Bogolyubsky and a prince in north-⁠eastern Rus. He is commemorated in the Greek calendar on 28 March (new style, the calendar of the Church of Greece) as a right-⁠believing saint, and the English calendar calls him prince of Vladimir-⁠Suzdal and places him in the year 1173. According to the chronicles, he died on a 28 March, the year being reckoned as 1172 or 1173, and was buried in the Dormition Cathedral at Vladimir.

In 1169 his father set him at the head of a coalition of princes against Kiev, and in 1172 he led the army in a campaign against the Volga Bulgars. The sources consulted do not say when and by whom he was canonized; he is honoured in calendars, without a known synodal canonization.
