Siméon Mstislavitch

Siméon Mstislavitch (Simeon Mstislavich) was prince of Vyazma and of Torzhok, who died in 1406 at Torzhok, and is venerated locally as a devout prince in the Smolensk region. He was killed in 1406, together with his wife, Ulyana.

His fate was bound with that of Prince Yury Svyatoslavich of Smolensk. After Vytautas took Smolensk in 1403, Yury went to Great Novgorod, and Prince Simeon followed him. In 1406 he moved with him to Torzhok, half of which he received from the Grand Prince of Moscow. In the same year, according to the chronicle, Yury Svyatoslavich came from Novgorod to Moscow, received Torzhok and killed Prince Simeon Mstislavich and his princess Ulyana there. His memory is kept on 21 December and on the Sunday before the feast of the Smolensk icon of the Mother of God, in the synaxis of the saints of Smolensk (new style).
