deprived Kublai of all his commands, and ordered him to proceed to Karakoram. At this harsh and unmerited treatment Kublai showed himself inclined to rebel and dispute his brother's authority. If he had done this, although the provocation was great, he would have confirmed the charges of his accusers, and a war would have broken out among the Mongols which would probably have rent their power in twain in Eastern Asia. But fortunately Yaochu was at hand to give prudent advice, and after much hesitation Kublai yielded to the impressive exhortations of his experienced and sagacious minister. He is reported to have addressed Kublai in the following terms: "Prince! You are the brother of the emperor, but you are not the less his subject. You cannot, without committing a crime, question his decisions, and, moreover, if you were to do so, it would only result in placing you in a more dangerous predicament, out of which you could hardly succeed in extricating yourself, as you are so far distant from the capital where your enemies seek to injure you. My advice is that you should send your family to Mangu, and by this step you will justify yourself and remove any suspicions there may be."

Kublai adopted this wise course, and proceeded in person to Karakoram, where he succeeded in proving his innocence and in discomfiting his enemies. It is said that Mangu was so affected at the mere sight of his brother that he at once forgave him without waiting for an explanation and reinstated him in all his offices. To ratify this reconciliation Mangu proclaimed that he would take the field in person, and that Kublai should hold joint command with himself. When he formed this resolution to proceed to China in person, he appointed his next brother, Arikbuka, to act as his lieutenant in Mongolia. It is necessary to recollect this arrangement, as Mangu died during the campaign, and it led to the separation of the Chinese empire and the Mongolian, which were divided after that event between Kublai and Arikbuka.

Mangu did not come to his resolution to prosecute the war with the Sungs any too soon, for Uriangkadai was beginning to find his isolated position not free from danger. Large as the army of that general was, and skillfully as he had endeavored to improve his position by strengthening the fortresses and recruiting from the warlike tribes of Yunnan, Uriangkadai found himself threatened by the collected armies of the Sungs, who occupied Szchuen with a large garrison and menaced the daring Mongol general with the whole of their power. There seems every reason to believe that if the Sungs had acted with only ordinary promptitude they might have destroyed this Mongol army long before any aid could have reached it from the north. Once Mangu had formed his resolution the rapidity of his movements left the Sungs little or no chance of attacking Uriangkadai. This campaign began in the winter of 1257, when the troops were able to cross the frozen waters of the Hoangho, and the immense Mongol army was divided into three bodies, while Uriangkadai was ordered to march north and effect a junction with his old chief Kublai in Szchuen. The principal fighting of the first year occurred in this part of China, and Mangu hastened there with another of his armies. The Sung garrison was large, and showed great courage and fortitude. The difficulty of the country and the strength of several of their fortresses seconded their efforts, and after two years' fighting the Mongols felt so doubtful of success that they held a council of war to decide whether they should retreat or continue to prosecute the struggle. It has been said that councils of war do not come to bold resolutions, but this must have been an exception, as it decided not to retreat, and to make one more determined effort to overcome the Chinese. The campaign of 1259 began with the siege of Hochau, a strong fortress, held by a valiant garrison and commander, and to whose aid a Chinese army under Luwenti was hastening. The governor, Wangkien, offered a stout resistance, and Luwenti succeeded in harassing the besiegers; but the fall of the fortress appeared assured, when a new and more formidable defender arrived in the form of dysentery. The Mongol camp was ravaged by this foe, Mangu himself died of the disease, and those of the Mongols who escaped beat a hasty and disorderly retreat back to the north. Once more the Sungs obtained a brief respite.

The death of Mangu threatened fresh disputes and strife among the Mongol royal family. Kublai was his brother's lawful heir, but Arikbuka, the youngest of the brothers was in possession of Karakoram, and supreme throughout Mongolia. He was hostile to Kublai, and disposed to assert all his rights and to make the most of his opportunities. No Great Khan could be proclaimed anywhere save at Karakoram, and Arikbuka would not allow his brother to gain that place, the cradle of their race and dynasty, unless he could do so by force of arms. Kublai attempted to solve the difficulty by holding a grand council near his favorite city of Cambaluc, the modern Pekin, and he sent forth his proclamation to the Mongols as their Khan. But they refused to recognize one who was not elected in the orthodox fashion at Karakoram; and Arikbuka not merely defied Kublai, but summoned his own kuriltai at Karakoram, where he was proclaimed Khakhan in the most formal manner and with all the accustomed ceremonies. Arikbuka was undoubtedly popular among the Mongols, while Kublai, who was regarded as half a Chinese on account of his education, had a far greater reputation south of the wall than north of it. Kublai could not tolerate the open defiance of his authority, and the contempt shown for what was his birthright, by Arikbuka; and in 1261 he advanced upon Karakoram at the head of a large army. A single battle sufficed to dispose of Arikbuka's pretensions, and that prince was glad to find a place of refuge among the Kirghiz. Kublai proved himself a generous enemy. He sent Arikbuka his full pardon, he reinstated him in his rank of prince, and he left him virtually supreme among the Mongol tribes. He retraced his steps to Pekin, fully resolved to become Chinese emperor in reality, but prepared to waive his rights as Mongol Khan. Mangu Khan was the last of the Mongol rulers whose authority was recognized in both the east and the west, and his successor, Kublai, seeing that its old significance had departed, was fain to establish his on a new basis in the fertile, ancient and wide-stretching dominions of China.

Before Kublai composed the difficulty with Arikbuka he had resumed his operations against the Sungs, and even before Mangu's death he had succeeded in establishing some posts south of the Yangtsekiang, in the impassability of which the Chinese fondly believed. During the year 1260 he laid siege to Wochow, the modern Wouchang, but he failed to make any impression on the fortress on this occasion, and he agreed to the truce which Litsong proposed. By the terms of this agreement Litsong acknowledged himself a Mongol vassal, just as his ancestors had subjected themselves to the Kins, paid a large tribute, and forbade his generals anywhere to attack the Mongols. The last stipulation was partly broken by an attack on the rear of Uriangkadai's corps, but no serious results followed, for Kublai was well satisfied with the manner in which the campaign terminated, as there is no doubt that his advance across the Yangtsekiang had been precipitate, and he may have thought himself lucky to escape with the appearance of success and the conclusion of a gratifying treaty. It was with the reputation gained by this nominal success, and by having made the Sungs his tributaries, that Kublai hastened northward to settle his rivalry with Arikbuka. Having accomplished that object with complete success, he decided to put an end to the Sung dynasty. The Chinese emperor, acting with strange fatuity, had given fresh cause of umbrage, and had provoked a war by many petty acts of discourtesy, culminating in the murder of the envoys of Kublai, sent to notify him of his proclamation as Great Khan of the Mongols. Probably the Sung ruler could not have averted war if he had shown the greatest forbearance and humility, but this cruel and inexcusable act precipitated the crisis and the extinction of his attenuated authority. If there was any delay in the movements of Kublai for the purpose of exacting reparation for this outrage, it was due to his first having to arrange a difficulty that had arisen in his relations with the King of Corea. That potentate had long preserved the peace with his Mongol neighbors, and perhaps he would have remained a friend without any interruption, had not the Mongols done something which was construed as an infraction of Corean liberty. The Corean love of independence took fire at the threatened diminution of their rights, they rose en masse in defense of their country, and even the king, Wangtien, who had been, well disposed to the Mongol rulers, declared that he could not continue the alliance, and placed himself at the head of his people. Seeing himself thus menaced with a costly war in a difficult country on the eve of a more necessary and hopeful contest, Kublai resorted to diplomacy. He addressed Wangtien in complimentary terms and disclaimed all intention of injuring the Coreans, with whom he wished to maintain friendly relations, but at the same time he pointed out the magnitude of his power and dilated on the extent of the Mongol conquests. Half by flattery and half by menace Kublai brought the Corean court to reason, and Wangtien again entered into bonds of alliance with Cambaluc and renewed his old oaths of friendship.

At this point of the long struggle with the Sungs it will be appropriate to consider what was the exact position of Kublai with regard to his own Chinese subjects, who now formed the backbone of his power. By this time Kublai had become to all practical intents and purposes a Chinese emperor. He had accepted all the traditional functions of the typical Hwangti, and the etiquette and splendor of his court rivaled that of the Sungs. He had not merely adopted the Chinese system of taxation and the form of administration to which the larger portion of his officials, being of Chinese race, had been accustomed, but he declared himself the patron of learning and of Buddhism, which had gained a hold on the minds of the Mongols that it has not lost to the present day. One of the most popular of his early measures had been the order to liberate all the literate class among his Chinese prisoners, and they had formed the nucleus of the civil service Kublai attached to his interests and utilized as his empire expanded. In his relations with Buddhism Kublai showed not less astuteness, and in realizing that to attain durable success he must appeal to the religious side of human character, he showed that he had the true instincts of a statesman.

At this time two facts were clearly apparent. The Chinese were sunk in a low state of religious disbelief, and the Sung rulers were not disposed to play the part of regenerators of their country. The second fact was that the only vigorous religion in China, or, indeed, in Eastern Asia, was Buddhism, which, since the establishment of Brahmanism in India, had taken up its headquarters in Tibet, where, however, the supreme authority was still secular--that is to say, it was invested in the hands of a prince or king, and not in those of a priest or Grand Lama. It so happened that there was resident at Kublai's court a Tibetan priest, of the family which had always supplied the Sanpou with his minister, who gained the ear of Kublai, and convinced him how politic and advantageous to him personally it would be if he were to secure the co-operation and sympathy of his priestly order. Kublai fell in with his plans, and proclaimed his friend Pakba Lama, and sent him back to Tibet, there to establish the ecclesiastical authority, which still exists in that country, in intimate alliance and sympathy with the Chinese rulers. By this and other similar proceedings Kublai gained over to his side several influential classes among the Chinese people, and many reflecting persons thought they saw in him a true regenerator of the empire, and a worthy successor of their greatest rulers. It was, therefore, with a thoroughly pacified country, and to a great extent a contented people, that Kublai began his last war with the rulers of Southern China.

In 1263 Kublai issued his proclamation of war, calling on his generals "to assemble their troops, to sharpen their swords and their pikes, and to prepare their bows and arrows," for he intended to attack the Sungs by land and sea. The treason of a Chinese general in his service named Litan served to delay the opening of the campaign for a few weeks, but this incident was of no importance, as Litan was soon overthrown and executed. Brief as was the interval, it was marked by one striking and important event--the death of Litsong, who was succeeded by his nephew, Chowki, called the Emperor Toutsong. Litsong was not a wise ruler, but, compared with many of his successors, he might be more accurately styled unfortunate than incompetent. Toutsong, and his weak and arrogant minister, Kiassetao, hastened to show that there were greater heights of folly than any to which he had attained. Acting on the advice of a renegade Sung general, well acquainted with the defenses of Southern
