Taking into consideration these several facts, is it not possible, that the White Tatars of Schiltberger are to be identified with those of the White Horde of Eastern writers; the Blue, as they were sometimes alluded to by Russian annalists, perhaps because of their encampments on the shores of the Blue Sea, the Lake Aral? This Horde, as the patrimony of the elder branch of the house of Jujy, whose chief town was Ssaganak, near the upper Syr Darya, was dependent to a certain extent on the Golden Horde, ruled over by the descendants of Batou, the second son of Jujy. But this state of dependence was not of long duration, for towards the close of the 14th century, the famous Toktamish, a prince of the elder branch, succeeded in annexing the whole of the Golden Horde to his possessions, after having, with the assistance of Timour, rid himself of his uncle Ourous Khan. Having quarrelled with his protector, this ambitious man was under the necessity of courting the friendship of Bajazet, who was only too pleased to secure another ally against the threatening domination of the ruler of Jagatai; there is, therefore, nothing surprising in the fact of the sultan sending a certain number of Christian captives to Toktamish, were it only to console him for the unfortunate termination to his war with Timour in 1395. At all events, the partisans of Toktamish, who effected their escape under the leadership of Timour Tash, upon the defeat of the former near the banks of the Terek, were received by the sultan with open arms. Savelieff (_Mon. Joud._, 314) gives it as his opinion, that Timour Tash who held the Crimea under the suzerainty of Toktamish, was himself a member of the Jujy family; in which case the sovereign of Sebaste might well have given his daughter in marriage to him, without contracting a misalliance, and the very nature of this alliance, may have incited Timour Tash to treat his benefactor with ingratitude in laying siege to Sebaste, his whole household being in his suite, after the custom of the country. Having necessarily become reconciled with the sultan, he might easily have treated him with treachery at the battle of Angora, by passing over to the ranks of his countrymen; in such a case they would have obtained a victory, in consequence of defection amongst the Tatars in the service of Bajazet, as we are informed by Arabian authors, and not, as Persian and Turkish historians have imagined, through defection among “the Turk princes of Asia Minor”. It is, nevertheless, no easy matter to reconcile this hypothesis with the statement made by Clavijo (_Hakluyt Soc. Publ._, 75). After alluding to the capture of Sebaste by Timour, the Spanish envoy continues:—“Before he arrived there, he met with a race called the White Tartars, who always wander over the plain; and he fought and conquered them, and took their lord prisoner; and took away as many as fifty thousand men and women with him. He then marched to Damascus,” etc., etc.
