Great Horde in the context of Ahmed Khan bin Küchük

Ivan III Vasilyevich (Russian: Иван III Васильевич; 22 January 1440 – 27 October 1505), also known as Ivan the Great, was Grand Prince of Moscow and all Russia from 1462 until his death in 1505. Ivan served as the co-ruler and regent for his blind father Vasily II before he officially ascended the throne.

He multiplied the territory of his state through conquest, purchase, inheritance and the seizure of lands from his dynastic relatives, and laid the foundations of the centralized Russian state. He also renovated the Moscow Kremlin and introduced a new legal code. Ivan is credited with ending the dominance of the Tatars over Russia; his victory over the Great Horde in 1480 formally restored its independence.

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.
