Muscovite Civil War
The Muscovite Civil War, or Great Feudal War, was a prolonged conflict that cast its shadow over the entire reign of Vasily II of Moscow (from 1425 to 1453). The two warring parties were Vasily II, the Grand Prince of Moscow, as one party, and his uncle, Yury Dmitrievich, the Prince of Zvenigorod, and the sons of Yuri Dmitrievich, Vasily Kosoy and Dmitry Shemyaka, as the other party. In the intermediate stage, the party of Yury conquered Moscow, but in the end, Vasily II regained his crown. It was the first civil war in the history of Muscovy, whose largely peaceful rise had been predicated on a lack of conflict within the ruling family.
