Denga - Yury Dmitrievich

Yury Dmitrievich seized Moscow from his nephew Vasily II twice — briefly in 1433 and again in 1434 — making his coin-issuing window one of the shortest and most politically turbulent of any Muscovite ruler. He died in June 1434 while still holding the city, ending a dynastic conflict that would drag on for another two decades as the Muscovite civil war.
