Arik Buga, left without friends, troops or resources, decided in 1264 to appeal to the mercy of his brother, and went to him. On [[338]]appearing at Kubilai’s tent men threw the curtain of the entrance around him; thus covered he made his prostrations. Such was the usage in cases of that kind. Admitted to the interior, he stood in the place given usually to secretaries. Kubilai looked at him long, and, seeing that he wept, could not repress his own tears and emotion. “Ah, my brother,” said he at last, “who was right, thou or I?” “I at first, but to-day the right is on thy side,” replied Arik Buga.

At this moment Atchigai, brother of Apishga, approached Assutai and asked: “Is it thou who killed my brother?” “I killed him at command of Arik Buga, at that time my sovereign. He did not wish that a prince of our house should die by the hand of some common man. Kubilai is my sovereign now; should he command, I would kill even thee in like manner.”

Kubilai imposed silence, and added: “This is not the time for such speeches.”

Togachar, a nephew of Jinghis, rose then and said: “The Khan desires no mention to-day of the past. He wishes you to feel nothing but pleasantness.” Turning to Kubilai then, he added: “Arik Buga is standing; what place dost thou give him?” He was seated with Kubilai’s sons and they passed that day in company. On the morrow, however, Arik Buga’s officers were all put in irons, and Kubilai appointed a commission of four princes and three generals to interrogate Arik Buga and his partisans. Arik Buga declared that he alone was responsible, that his officers were not guilty in any way. “How not guilty?” asked Kubilai. “The generals opposed to Mangu drew no bow against him; still it is known to thee how they were punished, simply for intentions. Ye who have begun civil war and slain so many princes and warriors, what are your deserts?” The officers made no reply. “My friends,” said Tuman Noyon, the most aged among them, “do ye not remember, that in raising Arik Buga to the throne we swore to die for his cause should the need come? The moment has come to make good that promise.”

Kubilai praised this fidelity and asked Arik Buga again, who had roused him to the enterprise. He declared at last that Alemdar and Bolga had said to him: “Hulagu and Kubilai are on distant expeditions, and our late sovereign has left you at the head of the principal ulus of the Mongols. Why hesitate? Make yourself [[339]]Grand Khan immediately.” He had consulted with the other officers; all held that opinion together. The officers present confirmed what Arik Buga had stated, and ten of them were sentenced to pay the death penalty. But to judge Arik Buga himself Kubilai wished the presence of Hulagu, Berkai, and Algu. After waiting a long time for them, princes of the blood and generals then present in Mongolia met to determine the fate of Assutai and Arik Buga. Through regard for Kubilai they decided with one mind to grant life to both princes. This decision was taken to Hulagu, Berkai and Algu for their approval. Algu replied, that, since he held power and office with Kubilai’s consent, he would give no opinion; the other two confirmed the decision.

Arik Buga and Assutai were set at liberty to render homage to the Khan and move about freely. One month later Arik Buga died of illness and was buried near Jinghis and Tului (1266).

The death of Arik Buga, his brother, did not save the great Emperor from civil war, and a long and terrible contest: Kaidu, a grandson of Ogotai, had his claim to the headship of the Mongols. He brought that claim forward and pushed it with such power, skill and resource that Kubilai had not strength enough to suppress him.

This struggle between the descendants of Ogotai and Tului was the greatest and by far the most striking event in the history of Jinghis Khan’s family. Though Kubilai was able to conquer all China and Burma he could not conquer Kaidu. He met him and held him in check,—he had power to do that, and to found at the same time a dynasty in China, but he could not crush him.

We will consider first the subjection of China, and then turn to Kaidu and his exploits.

Kubilai, now Grand Khan, had decided to conquer all China and he began that great work with seriousness. During 1260 he had sent an envoy named Hao king to inform the Sung Emperor of his election. This envoy was to see in addition that the treaty concluded at Wu chang fu with Kia se tao was respected. As soon as the envoy set foot on Sung territory he was cast into prison with all his attendants. This was done at direction of Kia se tao, the real author of the treaty by which the Sung Emperor was made a vassal of Kubilai. Kia se tao had removed from this world every person who knew of that treaty and its various provisions. He was [[340]]the only man living at that time in China who knew of it. The great point for Kia se tao was that the Sung Emperor must continue in ignorance of his thraldom. This man, whose sacred duty it was to explain the position, used his best power to conceal it, and adhered to his own direful policy at all costs. No one knew the great tragedy of China’s position save Kia se tao, first minister of the Empire.
