Yuri Danilovich

Yuriy Danilovich, also known as Georgiy Danilovich (Юрий Данилович in Russian) (1281 – 21 November 1325) was Prince of Moscow (1303–1325) and Grand Prince of Vladimir (from 1318).

Yury was the oldest son of Daniel, the first prince of Moscow. His first official action was to defend Pereslavl-Zalessky against Grand Duke Andrew III. Upon Andrew's death the next year, Yury had to contend the title of Grand Duke of Vladimir with Mikhail of Tver. While the Tverian army besieged Pereslavl and Moscow itself, Mikhail went to the Golden Horde, where the Khan elevated him to the supreme position among Russian princes.

In the meantime, Yury arranged the murder of Prince Konstantin of Ryazan. This unlucky ruler had been captured by Yury's father back in 1302 and had been incarcerated in Moscow since then. While Ryazan was shocked by such a barbarity, Yury annexed the key Ryazanian fortress of Kolomna to Moscow Duchy. He also captured Mozhaisk, which formerly belonged to the princes of Smolensk. By 1314, Yury secured backing from the Metropolitan Peter and formed an alliance with Novgorod against Tver. Now, he felt strong enough to challenge Mikhail of Tver in the Horde.

In 1315 Yury went to the Golden Horde and, after spending two years there, constructed an alliance with Uzbeg Khan. Upon Yury's marriage to the khan's sister Konchaka, Uzbeg Khan deposed Mikhail and nominated Yury as the Grand Duke of Vladimir. Back in Russia with a large force of Mongols, Yury approached Tver. However, Yuri's army was defeated and his brother Boris and his wife were taken prisoners. Thereupon he fled to Novgorod and sued for peace. At that time his wife, still held in Tver as a hostage, died unexpectedly. Yury availed himself of the confusion that followed and announced to the khan that she had been poisoned on Mikhail's order. The khan summoned both princes to Sarai and, after a trial, had Mikhail executed.
