Thirty years after this peace between Mahmud and Sandjar, Behramshah, the last prince but one of the once powerful dynasty of the sultans of Gasna, attempted to shake off the yoke of the Seljukides; feeling, however, the enterprise to be beyond his powers, he sent ambassadors to renew his homage to Sandjar. With him he succeeded, but not so with Hossein Jehansus, the founder of the Indian dynasty of the Gurides, who, about this time,[137] raised themselves on the ruin of the power of the Gasnewides. Behramshah, the Gasnewide, yielded to the power of Hossein, the Guride, as did the latter to that of Sultan Sandjar, who drove the founder of the Gurides out of Khorassan, and then appointed him his viceroy of the Indian province of Gur (whence the name of the dynasty). The fortune, which had smiled on Sandjar in his enterprises against Mahmud, Behramshah, and Hossein, was not so favourable to him, in his wars against the people of Karakhatai, whom he attacked in the obscurity of their forests; nor against the Turcomans of the race of Oghuz, who invaded Khorassan. He lost, in the battle which he fought with Gurjash, the prince of the former, thirty thousand men, together with his harem; and Tarkhau Khatun, the first of his wives, was made captive by the Karakhtaiyis. Still worse was his success against the Oghuz Turcomans, whom he wished to compel to an annual tribute of sheep, which they refused. He was taken prisoner by them, and confined, for four years, in an iron cage. The Turkish historians, who relate this unworthy treatment of the great Sultan Sandjar, deny Sultan Bajazet’s having experienced the same from his conqueror, Timur.
