According to his father’s will, Iurii Dmitrievich was to become grand prince after the death of his brother Vasilii I Dmitrievich. Iurii Dmitrievich led campaigns into the Novgorod lands and against the princes of the Suzdal’–Nizhny Novgorod Principality and the detachments of the Golden Horde. In 1425 he entered into a struggle with Vasilii II Vasil’evich for the grand prince’s throne (seeFEUDAL WAR IN RUSSIA IN THE SECOND QUARTER OF THE 15TH CENTURY).
On the initiative of Iurii Dmitrievich, a number of important cathedrals were built—the Uspenskii Cathedral in Zvenigorod, the Rozhdestvenskii Cathedral of the Savvino-Storozhevskii Monastery (Zvenigorod), and the Troitskii Cathedral of the St. Sergius Trinity Monastery (present-day Zagorsk).
