トゥグルク・ティムール
Under Tughlugh Timur, both amirs Tuluk and Bulaji had held the office of "ulus beg". After the death of Bulaji the office was given to his son Khudaidad. This was contested by Bulaji's brother, Qamar ud-Din, who desired to be "ulus beg" himself. His request for the office to be transferred to him was refused by Tughlugh Timur; consequently after the latter's death Qamar ud-Din revolted against Tughlugh Timur's son Ilyas Khoja Khan. He was likely responsible for the death of Ilyas Khoja; most of the family members of Tughlugh Timur were also killed. Qamar ud-Din proclaimed himself khan (the only Dughlat ever to do so) and, although he did not gain the support of many of the amirs, managed to maintain his position in Moghulistan.
