The khanate closely connected with the history of Russia was that of Kipchak or the Golden Horde, the khans of which settled, as we have seen, on the lower Volga and built for themselves a capital called Sarai.
At last in 1378 Toktamish, of the Eastern Kipchaks, succeeded in ousting all rivals, and establishing himself as ruler of eastern and western Kipchak.
During the forty-five years after the death of Omar (he died in 1822) the khanate of Khokand was the seat of continuous wars between the settled Sarts and the nomad Kipchaks, the two parties securing the upper hand in turns, Khokand falling under the dominion or the suzerainty of Bokhara, which supported Khudayar-khan, the representative of the Kipchak party, in 1858-1866; while Alim-kul, the representative of the Sarts, put himself at the head of the gazawat (Holy War) proclaimed in 1860, and fought bravely against the Russians until killed at Tashkent in 1865.
Olgierd's most memorable feat was his great victory over the Tatars at Siniya Vodui on the Bug in 1362, which practically broke up the great Kipchak horde and compelled the khan to migrate still farther south and establish his headquarters for the future in the Crimea.
One of the most formidable of his opponents was Toktamish, who after having been a refugee at the court of Timur became ruler both of the eastern Kipchak and the Golden Horde, and quarrelled with Timur over the possession of Khwarizm.
