In 1465, Ahmed Khan seized power in the Horde by rising against his brother Mahmud bin Küchük, who had been its ruler since 1459.
In 1472, Ahmed Khan entered into alliance with the Polish king Casimir IV against Ivan III of Russia.
In 1480, Ahmed Khan organized another military campaign against Muscovy, which would result in the Great Stand on the Ugra River, 150 miles from Moscow.
Panic set in, as both sides suddenly turned, deciding to flee rather than fight in the tradition of Genghis Khan.
Ahmed Khan's wife was the Timurid princess Badi' al-Jamal, a sister of Sultan Husayn Bayqara of Khorasan.
