Yury of Moscow

Yury (Georgy) Danilovich (Russian: Юрий (Георгий) Данилович; 1281 – 21 November 1325) was Prince of Moscow from 1303 to 1325 and Grand Prince of Vladimir from 1318 to 1322. He contested the title of Grand Prince of Vladimir with his uncle Mikhail of Tver. As Yury's father had never held the title, he had no legitimate claim. Despite two failed campaigns by Mikhail to subdue Yury, the latter allied with the Golden Horde and married the khan's sister Konchaka. However, he never had any children with her and was made grand prince after Mikhail's execution in 1318.

Yury III faced resistance and difficulties in collecting tribute for the Horde, prompting several punitive expeditions. In 1322, Mikhail's son Dmitry of Tver accused him of embezzlement and obtained the grand princely title. Dmitry also succeeded in killing Yury. Before his death, Yury led a campaign against the Swedes and founded a fort at the Neva River.
