The Battle of Kulikovo was fought between the armies of the Golden Horde, under the command of Mamai, and various Russian principalities, under the united command of Prince Dmitry of Moscow. The battle took place on 8 September 1380, at the Kulikovo Field near the Don River (now Tula Oblast, Russia) and was won by Dmitry, who became known as Donskoy, 'of the Don' after the battle. Although the victory did not end Mongol domination over Rus, it is widely regarded by Russian historians as the turning point at which Mongol influence began to wane and Moscow's power began to rise. The process eventually led to Grand Duchy of Moscow independence and the formation of the modern Russian state.
