The Great Stand on the Ugra River (Russian: Великое стояние на Угре) or the Standing on the Ugra River, also known as the Battle of the Ugra, was a standoff in 1480 on the banks of the Ugra River between the forces of Akhmat Khan of the Great Horde, and Grand Prince Ivan III of the Grand Duchy of Moscow. After Ivan III stopped paying tribute to the Horde, Akhmat Khan led an army towards Moscow, leading to a standoff between the two armies on the banks of the river. Akhmat Khan waited for his Lithuanian reinforcements to arrive, but they never did, with one Mongol attempt to cross the river failing leading Akhmat Khan to retreat. Both armies departed after little fighting. Nevertheless, the outcome of the campaign corresponded to the strategic plan of the Russians to defend the capital and the border from the Tatars. In Russian historiography, it has been interpreted as the end of the "Tatar yoke" in Russia, though some historians believe that the event itself was insignificant and did not change Russo-Tatar relations. Nevertheless, the event is usually regarded as the end of nominal Tatar suzerainty over Russia. This did not end the threat from the Tatars to the Russians.
