The 'Great Horde', or 'Big Horde' was the central principality of the Mongol-Tartar
Golden Horde, the westernmost successor state of
Genghis Khan's legacy.
Following
Timur's invasion (roughly reconstituting the Persia-based
Ilkhanate), the Golden Horde started to disintegrate. The major principalities of
Kazan and
Crimea gained independence as princely khanates. The Russian rising power
Muscovy,
Astrakhan Khanate,
Nogay Horde and
Siberia Khanate followed. The remaining territory around capital
Saray on the Volga still claimed to be the legitimate khanate of the Golden Horde, but it retained neither the political clout nor the military might of the original Golden Horde. In
1502 the Great Horde was completely destroyed by
Meñli I Giray of the
Crimean Khanate, by then an Ottoman tributary state. Ultimately all these Turkic polities were to fall prey to Russian forces, including Cossack armies.
