Jabbār Berdi (Turki/Kypchak and Persian: جبار بردی; the name is rendered as Yeremferden in some western sources),[1] was the khan of the Golden Horde, reigning twice, in 1414–1415 and 1416–1417.
[2] Tokhtamysh's son Karīm Berdi broke with his family's traditional alliance with Grand Prince Vytautas of Lithuania, and assumed a hostile attitude.
Nevertheless, Karīm Berdi was apparently still at large, and Jabbār Berdi had another dangerous enemy in the beglerbeg Edigu, who had already proclaimed his own khan, a Tuqa-Timurid named Chekre.
Later the same year, Jabbār Berdi was defeated by Edigu and fled to the Crimea.
Edigu declared another Tuqa-Timurid, Darwīsh khan, while Jabbār Berdi was killed by his own retinue as he attempted to seek refuge in Lithuania.
