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.
