Having suffered a further defeat at the hands of Qādir Berdi, Edigu fled to the east and Sibir, where he proclaimed as khan the Shibanid Ḥājjī Muḥammad.
Although he naturally had Ḥājjī Muḥammad's support, Edigu died of mortal wounds sustained in battle against the forces of Qādir Berdi later the same year.
As Qādir Berdi himself perished in the struggle at this time, Edigu's sons, led by Manṣūr, quickly succeeded in making Ḥājjī Muḥammad the monarch of the majority of the territory of the Golden Horde.
[4] Ḥājjī Muḥammad's success, however, was tenuous and short-lived, especially where the western part of the Golden Horde was concerned, as he was soon faced with opposition by several rivals for the throne and their supporters.
The first assertions of the claims of Ulugh Muḥammad, supported by the Shīrīn emir Tekne, are dated variously to 1419 or 1421 or even 1424, and there is much confusion among scholars as to which khan is designated in the historical sources.
