QÃÂdir Berdi (Turki/Kypchak and Persian: ÃÂçïñ èñïÃÂ) was briefly the khan of the Golden Horde in 1419.
QÃÂdir Berdi was one of the several sons of Tokhtamysh Khan to reign briefly in the early fifteenth century. They were descendants of Tuqa-Timur, the son of Jochi, the son of Chinggis Khan. QÃÂdir Berdi's mother is said to have been a Circassian concubine.
In 1417, the beglerbeg Edigu eliminated Tokhtamysh's son JabbÃÂr Berdi and made khan another Tuqa-Timurid, Darwësh. For a short while, Edigu seemed to have triumphed over his foes, the sons of Tokhtamysh. However, there was yet another one of them, QÃÂdir Berdi, able and willing to claim his father's throne, once more with the support of Grand Prince Vytautas of Lithuania. In the summer of 1419, QÃÂdir Berdi advanced from Lithuania into the Golden Horde, and apparently eliminated Darwësh Khan, assuming the throne of the Golden Horde. QÃÂdir Berdi's reign found support from the sons of his sister JÃÂnika: emir Tegene Bey of the Shirin clan and Edigu's son Nà «r ad-Dën, who was often in disagreement with his father. QÃÂdir Berdi issued coins at Bolghar. Edigu had fled to the Crimea and proclaimed yet another Tuqa-Timurid, Beg á¹¢à «fë, as his khan, while sending an envoy to seek peace from Vytautas, in vain. QÃÂdir Berdi pressed his advantage, defeating Edigu's new khan (who survived in the Crimea until 1421), and causing Edigu to flee eastward, toward his power base. Here he declared a new khan, the Shibanid ḤÃÂjjë Muḥammad, and swore his sons to uphold his cause. QÃÂdir Berdi continued his pursuit of Edigu, crossing the Volga and advancing to the Ural. Here in late 1419 or early 1420 he closed battle with Edigu, with fatal consequences for both leaders: QÃÂdir Berdi was killed in the fight and his forces dispersed; but Edigu's troops also routed and he also perished. He was heavily wounded in the battle and finished off on the orders of a former emir of Tokhtamysh, who had learned of Edigu's location. The opponents of Edigu's sons now looked to QÃÂdir Berdi's younger brother Kà «chuk Muḥammad (not to be confused with the later khan called Küchük Muḥammad) as their khan.
