Dmitry Donskoy - Struggle Against Mamai

Struggle Against Mamai

Dmitry's thirty-year reign saw the beginning of the end for Mongol domination of parts of what is now Russia. The Golden Horde was severely weakened by civil war and dynastic rivalries. Dmitry took advantage of this lapse in Mongol authority to openly challenge the Tatars.

While he kept the Khan's patent to collect taxes for all of Russia, Dmitry is also famous for leading the first Russian military victory over the Mongols. Mamai, a Mongol general and claimant to the throne, tried to punish Dmitry for attempting to increase his power. In 1378 Mamai sent a Mongol army, but it was defeated by Dmitry's forces in the Battle of Vozha River. Two years later Mamai personally led a large force against Moscow. Dmitry met and defeated it at the Battle of Kulikovo.

The defeated Mamai was presently dethroned by a rival Mongol general, Tokhtamysh. That khan reasserted Mongol rule over parts of what now is Russia and overran Moscow for Dmitry's resistance to Mamai. Dimitry, however, pledged his loyalty to Tokhtamysh and to the Golden Horde and was reinstated as Mongol principal tax collector and Grand Duke of Vladimir. Upon his death in 1389, Dimitry was the first Grand Duke to bequeath his titles to his son Vasiliy without consulting the Khan.
