Yury of Moscow in the context of "Neva River"

The Grand Principality of Moscow, or Muscovy, known as the Principality of Moscow before 1389, was a late medieval Russian monarchy. Its capital was the city of Moscow. Originally established as an appanage principality in the 13th century, the grand principality was transformed into a centralized Russian state in the late 15th century.

Moscow became a separate principality when Daniel (r. 1263–1303), the youngest son of Alexander Nevsky, received the city and surrounding area as an appanage. By the end of the 13th century, Moscow had become one of the leading principalities within the Vladimir grand principality, alongside Tver. A struggle between the princes of Moscow and Tver began after Mikhail of Tver became grand prince in 1304. Yury (r. 1303–1325) contested the title and was later made grand prince in 1318 by the khan of the Golden Horde, who held suzerainty over the princes. However, Yury would lose the title four years later.
