Qādir Berdi was one of the several sons of Tokhtamysh Khan to reign briefly in the early fifteenth century.
[1] In 1417, the beglerbeg Edigu eliminated Tokhtamysh's son Jabbār Berdi and made khan another Tuqa-Timurid, Darwīsh.
However, there was yet another one of them, Qādir Berdi, able and willing to claim his father's throne, once more with the support of Grand Prince Vytautas of Lithuania.
Edigu had fled to the Crimea and proclaimed yet another Tuqa-Timurid, Beg Ṣūfī, as his khan, while sending an envoy to seek peace from Vytautas, in vain.
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.
