4.3.3

The allies were beaten in a number of fights, and eventually fled for refuge to the territory of the Khakán (now Kúluk, a nephew of Uljaitu), while their dominions were appropriated by the house of Chaghatai, the clans who inhabited them becoming in part its subjects and in part those of the Kipchaks. "With Chapár," says Mr. Oliver, "the house of Oktai disappears, though representatives came to the front for a brief period again in the persons of Ali and of Dánishmanjah, while Timur (Tamerlane), after displacing the family of Chaghatai, selected his puppet khans from the Oktai stock." Within a year of his installation, Kabak made way for an elder brother, who ascended the throne of the Chaghatai under the name of Isan Bugha, though his historical identity (in connection with this name at least) is somewhat uncertain. He provoked the Khakan into war, and was beaten almost at the outset of his rule; afterwards he invaded Khorasan with a like result, and was finally forced to fly from the country, before the combined forces of one of his brothers and of the seventh Il-Khán, or King of Persia. This occurred in 1321, when Kabak seems to have resumed the throne which he had abdicated twelve years previously.
