Capitulation of Goryeo As Khagan, Möngke seemed to take the legacy of world conquest he had inherited much more seriously than had Güyük. His conquests were all directed at East Asia and the Middle East. In his first plans for additional conquests, Möngke chose
Korea and the
Dali Kingdom in
Yunnan in 1252. Möngke sent envoys to
Goryeo, announcing his coronation in October 1251. He also demanded that
King Gojong submit before him in person and to move his headquarters from
Ganghwa Island to the mainland of Korea. But the Goryeo court refused to send the king because he was elderly and unable to travel so far. Möngke dispatched his envoys with specific tasks again. The envoys were well received by the Goryeo officials, but they criticized the Goryeo officials because their king did not follow his overlord Möngke's orders. Möngke ordered prince Yeku to command the army against Korea. However, a Korean in the court of Möngke convinced them to begin their campaign in July 1253. Yeku, along with Amuqan, demanded that the Goryeo court surrender. The court refused but did not resist the Mongols and gathered the peasantry into mountain fortresses and islands. Working together with the Goryeo commanders who had joined the Mongols, Jalairtai Qorchi ravaged Korea. When one of Yeku's envoys arrived, Gojong personally met him at his new palace. The king Gojong sent his stepson as hostage to Mongolia. The Mongols agreed to a truce in January 1254. Möngke realized that the hostage was not the blood prince of the Goryeo dynasty and blamed the Goryeo court for deceiving him. Möngke's commander Jalairtai devastated much of Goryeo and took 206,800 captives in 1254. Famine and despair forced peasants to surrender to the Mongols. They established a
chiliarchy office at Yonghung with local officials. Ordering defectors to build ships, the Mongols began attacking the coastal islands from 1255 on. In the
Liaodong Peninsula, the Mongols formed Korean defectors into a colony of eventually 5,000 households. In 1258, the king and the Ch'oe clan retainer
Kim Chun staged a counter-coup, assassinated the head of the Ch'oe family, and sued for peace. When the Goryeo court sent the future king
Wonjong of Goryeo as hostage to the Mongol court and promised to return to
Gaegyeong, the Mongols withdrew from Korea.
Dali, Vietnam, and Tibet Möngke concerned himself more with the war in China, outflanking the
Song dynasty through the conquest of the
Kingdom of Dali (in modern
Yunnan) in 1254 and an invasion of Southeast Asia, which allowed the Mongols to invade from the north, west, and south. Möngke Khan dispatched Kublai to the
Dali Kingdom in 1253. The ruling family, Gao, resisted and murdered the Mongol envoys. The Mongols divided their forces into three. One wing rode eastward into the
Sichuan basin. The second column under Uryankhadai took a difficult way into the mountains of western Sichuan. Kublai himself headed south over the grasslands, meeting up with the first column. With Uryankhadai galloping in along the lakeside from the north, Kublai took the capital city of
Dali and spared the residents despite the slaying of his ambassadors. The Mongols appointed King Duan Xingzhi as local ruler and stationed a pacification commissioner there. After Kublai's departure, unrest broke out among the Black jang. By 1256, Uryankhadai, the son of
Subutai, had completely pacified Dali. in 1257 After subjugating the Dali, Kublai sent a column south under
Uriyangkhadai, the son of Subutai. Uriyangkhadai sent envoys to ask the
Vietnamese for a route to attack the
Southern Song, but the Tran Vietnamese imprisoned the Mongol envoys. In 1257, a Mongol column under Uriyangkhadai invaded Vietnam (then known as
Đại Việt) along with his son
Aju and an army of 3,000 Mongols and 10,000
Yi tribesmen. To avoid further war, the Tran sent tributes to the administration of Möngke. To strengthen his control over Tibet, Möngke made Qoridai commander of the Mongol and Han troops in Tibet in 1251. In 1252–1253,
Qoridai invaded Tibet, reaching as far as
Damxung. The Central Tibetan monasteries submitted to the Mongols, and the Mongol princes divided them as their
appanages.
Conflicts with the Delhi Sultanate In 1252–1253,
Sali Noyan of the
Tatar clan was sent to the Indian borderlands at the head of fresh troops and was given authority over the
Qara'unas. Sali himself was subordinate to Möngke's brother
Hulagu. Due to the internal conflicts of the
Delhi Sultanate, the
Mamluk Sultan
Nasiruddin Mahmud's brother, Jalal al-Din Masud, fled into Mongol territory in 1248. When Möngke was crowned as Khagan, Jalal al-Din Masud attended the ceremony and asked help from Möngke, who ordered Sali to assist him to recover his ancestral realm. Sali made successive attacks on
Multan and
Lahore.
Sham al-Din Muhammad Kart, the client malik of
Herat, accompanied the Mongols. Jalal al-Din was installed as client ruler of Lahore, Kujah, and
Sodra. In 1254 the Delhi official Kushlu Khan offered his submission to Möngke and accepted a Mongol
darughachi. When he failed to take Delhi, Kushlu turned to Hulagu. In the winter of 1257–1258, Sali Noyan entered
Sind in strength and dismantled the fortifications of Multan; his forces may also have invested the island fortress of Bakhkar on the
Indus. Möngke followed the schemes of his predecessor against the
Nizari Ismailis (Assassins). Möngke's decision to launch a campaign against Nizari castles followed anti-Nizari urges by Sunnis in the Mongol court, new anti-Nizari complaints (including Shams-ud-Din, the chief judge of
Qazvin), and warnings from local Mongol commanders in Persia. In 1252, Möngke entrusted the mission of conquering the rest of Western Asia to his brother
Hülegü, with the highest priority being the conquest of the Nizari state and the Abbasid Caliphate. In 1253, William of Rubruck went on a mission to Karakorum in Mongolia, was struck by the security precautions there, reportedly in response to the more than forty assassins who had been sent by Imam
Ala al-Din Muhammad there to assassinate Möngke; it is possible that the assassination attempt was merely rumored. Möngke ordered the Jochid and Chagataid families to join Hulagu's expedition to Iran and strengthened the army with 1,000 siege engineers from China. Möngke's armies, led by his brother Hulagu, launched an attack on the Ismailis in Iran, crushing the last major resistance there by the end of 1256. The Hashashin Imam Rukn ad-Din requested permission to travel to Karakorum to meet with the Great Khan Möngke himself. Hulagu sent him on the long journey to Mongolia, but once the Imam arrived there, Möngke criticized his action and dismissed him. Rukn ad-Din was killed in uncertain circumstances. For the
Abbasids, envoys from Baghdad attended the coronation of Möngke in 1251 to come to terms with the Mongols. However, Möngke told Hulagu that if the caliph
Al-Musta'sim refused to meet him in person, then Hulagu was to destroy Baghdad. Hulagu then advanced on
Iraq, taking the capital at Baghdad in 1258. Hulagu sent Möngke some of his war booty with the news of his conquest of Baghdad. Möngke dispatched a Chinese messenger to congratulate him for his victory. Outraged by the attack on the caliphate, Malik Kamil revolted, killing his Mongol overseer. Hulagu's son Yoshumut invested Mayyafariqin and executed Malik Kamil. From there they moved into
Syria in 1259, took
Damascus and Aleppo, and reached the shores of the Mediterranean. Fearing the Mongol advance, the Ayyubid Sultan Malik Nasir Yusuf refused to see Hulagu and fled. However, the Mongols captured him at
Gaza.
South China In 1241,
Töregene Khatun had sent an envoy to make peace proposals and discuss with Zhao Yun (posthumously known as
Emperor Lizong). The Song court arrested the envoy and imprisoned him in a fortress with his suite of seventy persons. The envoy died, but his suite were detained until 1254. That year the Mongol army attacked to take Hejiu but failed. The Chinese freed the suite of the late envoy to show their desire for peace. Möngke concentrated all his attention on the conquest of the
Song dynasty. Taking personal command late in the decade, he captured many of the fortified cities along the northern front. In 1252, Möngke commissioned Kublai and experienced general
Uriyangkhadai to conquer the
Dali Kingdom. From the summer of 1253 to early 1254, Möngke forbade his army to plunder civilians. When his son accidentally destroyed a
crop in the field of the Chinese peasants, Möngke punished him. On 18 February 1259,
Tsagaan Sar, the Mongol New Year feast was given by Möngke near the mountain Zhonggui. At this feast his relative, Togan, a chief of the Jalairs, declared that
South China was dangerous because of its climate, and that the Great Khagan should go northward for safety. Baritchi of the Erlat tribe called this advice cowardly and advised Möngke to remain with his army. These words pleased Möngke who wished to take the city nearby. The Song commander slew his envoy who had been sent to ask the city's submission. In 1259, Uriyangkhadai's forces attacked
Guangxi as part of a coordinated Mongol attack in 1259 with armies attacking in Sichuan under Möngke and other Mongol armies attacking in modern-day
Shandong and
Henan. ==Wives, concubines, and children==
