(1.) “but he was killed in a battle.”—Tchadibek Khan was raised to the throne by Ydegou or Edekou in 1399, upon the death of his brother, Timour Koutlouh. The coins struck during his reign and Russian chronicles show, that his rule lasted until 1407, in the early part of which year Toktamish died near Tioumen, in Siberia, whither he had retired after his defeat by Ydegou and Timour Koutlouh in 1399. Clavijo says that he had effected a reconciliation with Timour, who desired to oppose him to Ydegou, the latter having refused to acknowledge his suzerainty. Upon his return from Siberia, Ydegou quarrelled with Tchadibek, who did not lose his life, but fled to the Caucasus, never again to return to the Horde—a statement which, though at variance with Schiltberger’s narrative, is based on a coin of the reign of Tchadibek, struck at Shemahà. Of this coin, Savelieff (_Mon. Joud._, ii, 225) says, “It certifies that although Tchadibek’s influence in the Horde was lost to him, he contrived to enjoy an appanage in the Caucasus.” But this unique coin might have been struck when Tchadibek was still at Saraï, for we learn from Dorn (_Versuch. einer Gesch. d. Schirwan-Sch._, 572) that prayers were offered at Shirwan in the name of Tchadibek, and in the presence of Ydegou so late as the year 1406, and nothing can force us to admit that the same honours would have been paid to the khan after his expulsion by that same amir, or that an appanage would have been bestowed upon him in the Caucasus.—BRUUN. (2.) “Polet, who reigned one year and a half.”—Schiltberger may have slightly shortened the duration of the reign of this khan, who was the son of Timour Koutlouh, and was placed on the throne by Ydegou, as successor to Tchadibek. His coins, struck at Saraï, Bolgar, and Astrahan, prove that he must have reigned in Kiptchak from 1407 to 1410, when he was expelled by Jalal uddin, the “Segelalladin” of the text, who was the son of Toktamish.—BRUUN.
