He was determined now to make a new incursion into Katay, and that with a larger force than he had had before. So he made an alliance with the chieftain of a neighboring tribe, called the Naymans; and, in order to seal and establish this alliance, he contracted that his son should marry the daughter of his ally. This was the time when Temujin was but thirteen years old. The name of this his first wife was Karizu--at least that was one of her names. Her father's name was Tayian. Before Yezonkai had time to mature his plans for his new invasion of Katay, he fell sick and died. He left five sons and a daughter, it is said; but Temujin seems to have been the oldest of them all, for by his will his father left his kingdom, if the command of the group of tribes which were under his sway can be called a kingdom, to him, notwithstanding that he was yet only thirteen years old.

In the language of the Monguls and of their neighbors the Tartars, a collection of tribes banded together under one chieftain was designated by a name which sounded like the word _orda_. This is the origin, it is said, of the English word _horde_. The orda over which Yezonkai had ruled, and the command of which, at his death, he left to his son, consisted of a great number of separate tribes, each of which had its own particular chieftain. All these subordinate chieftains were content to be under Yezonkai's rule and leadership while he lived. He was competent, they thought, to direct their movements and to lead them into battle against their enemies. But when he died, leaving only a young man thirteen years of age to succeed him, several of them were disposed to rebel. There were two of them, in particular, who thought that they were themselves better qualified to reign over the nation than such a boy; so they formed an alliance with each other, and with such other tribes as were disposed to join them, and advanced to make war upon Temujin at the head of a great number of squadrons of troops, amounting in all to thirty thousand men. The names of the two leaders of this rebellion were Taychot and Chamuka.
