Dmitry Shemyaka

Dmitriy Yurievich Shemyaka was the second son of Yury of Zvenigorod by Anastasia of Smolensk and grandson of Dmitri Donskoi. His hereditary patrimony was the rich northern town Galich-Mersky. When his uncle prince Vasily I of Moscow died in 1425, he and his 10-year-old nephew Vasily started fighting over the right to the throne, causing the Muscovite War of Succession (1425–1453). Intermittently, Shemyaka managed to be recognised twice as Prince of Moscow.
