Mikhail Yaroslavich of Tver

Mikhail Yaroslavich (1271–1318) became prince of Tver in 1285 and was named grand prince of Vladimir in 1304 after receiving his patent from the khan of the Golden Horde. His reign was dominated by his feud with Yury of Moscow.

In December 1317 he defeated Yury at Bortenevo and captured his wife, a sister of Uzbeg Khan; when she died in custody, he was charged with her murder. Summoned to Sarai, he was executed on 22 November 1318. The Russian Church later canonized him for meeting certain death meekly.
