Thus it was then that the Mughal i-mak was exterminated, with the exception of two males, Kayan and Naguz, and two females, their wives, and, hence, all Mughals whatsoever are descended from them—with the exception of those of the i-mak who followed the uncles of Aghuz into the farther east, according to the traditions contained in some works—and are not Tattars, although they are, by descent, Turks. From what has just been stated, and what has been previously mentioned, it will now be clearly seen why such hostility existed—and continues to exist to boundaries of Rum and Sham, fell into the hands of the this day—between the Turks of the Tattar I-mak, from that time known in the writings of Oriental historians under the general name of Turks as well as Tattars, and the descendants of the two Mughals who escaped this general massacre, and who were destined to become the progenitors of that sanguinary conqueror, the Chingiz Khan. This enmity, doubtless, burnt in the breasts of himself and his tribe, when he invaded and attacked the dominions of Sultan Muhammad, Khwarazm Shah, besides the provocation he had received through the treatment of his envoys and merchants, that Sultan being a Turk of the Tattar I-mak, and also allied to them by marriage.
