of Chaghatai.  Indeed, it is not easy to point out the mutual limits of their territories, and these must have been somewhat complex, for we find Kaidu and Borrak Khan of Chaghatai at one time exercising a kind of joint sovereignty in the cities of Bokhara and Samarkand.  Probably, indeed, the limits were in a great measure tribal rather than territorial.  But it may be gathered that Kaidu’s authority extended over Kashgar and the cities bordering the south slopes of the Thian Shan as far east as Kara Khoja, also the valley of the Talas River, and the country north of the Thian Shan from Lake Balkhash eastward to the vicinity of Barkul, and in the further north the country between the Upper Yenisei and the Irtish.

Kaidu died in 1301 at a very great age.  He had taken part, it was said, in 41 pitched battles.  He left 14 sons (some accounts say 40), of whom the eldest, called Shabar, succeeded him.  He joined Dua Khan of Chaghatai in making submission to Teimur Kaan, the successor of Kublai; but before long, on a quarrel occurring between the two former, Dua seized the territory of Shabar, and as far as I can learn no more is heard of the house of Kaidu.  Vambery seems to make the Khans of Khokand to be of the stock of Kaida; but whether they claim descent from Yunus Khan, as he says, or from a son of Baber left behind in his flight from Ferghana, as Pandit Manphul states, the genealogy would be from Chaghatai, not from Kaidu.

NOTE 2.—­“To the N.N.W. a desert of 40 days’ extent divides the states of Kublai from those of Kaidu and Dua.  This frontier extends for 30 days’ journey from east to west.  From point to point,” etc.; see continuation of this quotation from Rashiduddin, in Vol.  I. p. 214.

CHAPTER II.

OF CERTAIN BATTLES THAT WERE FOUGHT BY KING CAIDU AGAINST THE ARMIES OF HIS UNCLE THE GREAT KAAN.

Now it came to pass in the year of Christ’s incarnation, 1266, that this King Caidu and another prince called YESUDAR, who was his cousin, assembled a great force and made an expedition to attack two of the Great Kaan’s Barons who held lands under the Great Kaan, but were Caidu’s own kinsmen, for they were sons of Chagatai who was a baptized Christian, and own brother to the Great Kaan; one of them was called CHIBAI, and the other CHIBAN.[NOTE 1]

Caidu with all his host, amounting to 60,000 horse, engaged the Kaan’s two Barons, those cousins of his, who had also a great force amounting to more than 60,000 horsemen, and there was a great battle.  In the end the Barons were beaten, and Caidu and his people won the day.  Great numbers were slain on both sides, but the two brother Barons escaped, thanks to their good horses.  So King Caidu returned home swelling the more with pride and arrogance, and for the next two years he remained at peace, and made no further war against the Kaan.
