After the battle of Ghujduvān, in A.H. 918 (1512), in accordance with their established custom, _tūra_ and _yasāk_, the Shaybānī Sultans proceeded to elect their Khākān. Kuchunji Khān, as the eldest, was appointed to the high office; while Suyunjik was nominated _Kālgha_, or heir-apparent. The latter, however, died before Kuchunji, whereupon Jānībeg became the _Kālgha_; but he too predeceased Kuchunji, and the title of _Kālgha_ passed to Abū Sa`īd Khān, who eventually became Khākān, A.H. 936 (1529). On his death he was succeeded by `Ubaydullah Khān, A.H. 939 (1533). The various appanages of Transoxiana were thus apportioned in 918 by Jānībeg:--Kuchunji received Samarkand; Suyunjik, Tashkent; and `Ubaydullah, Karakul and Karshī, besides Bokhārā, which was his by inheritance. Jānībeg reserved for himself and his children all the country of Miyānkul, Soghd of Samarkand, and the town of Kerminé, which was his residence. Omitting the unimportant reigns of the seven following _Khākās_,[449] we will pass at once to a short account of the greatest of the Abū-l-Khayrides, `Abdullah II., the last but one of his dynasty; and for this purpose we cannot do better than summarise the account given by Professor Vambéry in his _History of Bokhara_[450]. In A.H. 964 (1556) he had put an end to the sub-dynasty of Bokhārā, and in A.H. 968 (1560) proclaimed his father in that town as “Khākān of the world”; in A.H. 986 (1578) he similarly abolished the sub-dynasty of Samarkand, which had sprung up during Iskandar’s reign at Bokhārā; and in A.H. 991 (1583), on his father’s death, he became Khākān.
