November 11, 1480 - The Battle of the Ugra is over. The Russian army put an end to the Tatar-Mongolian yoke.
As a state, the Golden Horde had effectively ceased to exist since the second half of the 15th century, having collapsed into several states, the main one being the Great Horde. The Grand Duke of Moscow Ivan III, who understood the position of the Horde, decided to end the forced dependence and stopped paying tribute.
A little earlier, the sovereign began to look for allies among the khans who had fallen from the Golden Horde. In 1472 Ivan III began diplomatic negotiations with the Crimean Khanate and in 1480 signed an alliance agreement with him against the Great Horde.
In 1476 Khan Akhmat ordered Ivan III to appear in great splendor to explain why Moscow did not pay tribute - which he refused. According to the laws of the time, the khan had to immediately move his army against the rebellious Moscow, but at this stage he settled relations first with the Uzbek khan, and then with Crimea. It was only in 1480 that Khan Akhmat gathered an army for a campaign against Rus and enlisted the support of the Polish king Casimir IV, who was also supposed to attack the Muscovite state from the west.
The year 1480 was not chosen by chance for the campaign against Moscow, since Ivan III solved complex issues at that time: the attack of the Knights of the Lebanese Order on Pskov and the rebellion of the brothers Prince Andrei Uglitsky and Boris Volotsky. During this difficult period for Ivan III, Khan Akhmet decided to bypass the border of the Moscow Principality from the west along the Oka and stand on the banks of the Ogra River at the Lithuanian border.
Adar soldiers approached Ugra in early October and immediately began fighting in several places. Russian soldiers managed to build fortifications. Using bows, arquebuses and artillery, they stopped new streams of Horde soldiers trying to cross the Ogra and gain a foothold on the Russian coast.
