Great stand on the Ugra river, a standoff between the forces of Akhmat Khan, Khan of the Great Horde, and the Grand Duke Ivan III of Russia, which results in the retreat of the Tataro-Mongols and the eventual disintegration of the Horde.
The Great Stand on the Ugra River (Russian: Великое cтояние на реке Угре, also Russian: Угорщина, romanized: Ugorshchina, derived from "Ugra") was a standoff between the forces of Akhmat Khan of the Great Horde, and the Grand Prince Ivan III of Muscovy in 1480 on the banks of the Ugra River, which ended when the Tatars departed without conflict. It is seen in Russian historiography as the end of Tatar/Mongol rule over Moscow.
