Great Khan of the Mongols The mysterious deaths of three
Jochid princes in Hulagu's service, the
siege of Baghdad, and unequal distribution of war spoils strained the Ilkhanate's relations with the Golden Horde. In 1262, Hulagu's complete purge of the Jochid troops and support for Kublai in his conflict with Ariq Böke brought open war with the Golden Horde. Kublai reinforced Hulagu with 30,000 young Mongols to stabilize the political crises in the western regions of the Mongol Empire. When Hulagu died on 8 February 1264, Berke marched to cross near
Tbilisi to conquer the Ilkhanate but died on the way. Within a few months of these deaths, Alghu Khan of the Chagatai Khanate also died. In the new official version of his family's history, Kublai refused to write Berke's name as the khan of the Golden Horde because of Berke's support for Ariq Böke and wars with Hulagu; however, Jochi's family was fully recognized as legitimate family members. (1375). The caption reads:
"The most powerful prince of the Tartars is named Holubeim [Kubilay Khan], which means Great Khan. This emperor is richer than any other emperor in the world. This emperor is protected by twelve thousand horsemen with their four captains that stay at the court three months of the year." Kublai Khan named
Abaqa as the new Ilkhan (obedient khan) and nominated Batu's grandson
Mentemu for the throne of
Sarai, the capital of the Golden Horde. The Kublaids in the east retained
suzerainty over the Ilkhans until the end of their regime. Kublai also sent his protege
Ghiyas-ud-din Baraq to overthrow the court of the
Oirat Orghana, the empress of the
Chagatai Khanate, who put her young son
Mubarak Shah on the throne in 1265, without Kublai's permission after her husband's death. Prince
Kaidu of the
House of Ögedei declined to personally attend the court of Kublai. Kublai instigated Baraq to attack Kaidu. Baraq began to expand his realm northward; he seized power in 1266 and fought Kaidu and the Golden Horde. He also pushed out Great Khan's overseer from the
Tarim Basin. When Kaidu and Mentemu together defeated Kublai, Baraq joined an alliance with the House of Ögedei and the Golden Horde against Kublai in the east and Abagha in the west. Meanwhile, Mentemu avoided any direct military expedition against Kublai's realm. The Golden Horde promised Kublai their assistance to defeat Kaidu whom Mentemu called the rebel. This was apparently due to the conflict between Kaidu and Mentemu over the agreement they made at the Talas kurultai. The armies of Mongol Persia defeated Baraq's invading forces in 1269. When Baraq died the next year, Kaidu took control of the Chagatai Khanate and recovered his alliance with Mentemu. Meanwhile, Kublai tried to stabilize his control over the
Korean Peninsula by mobilizing another Mongol invasion after he enthroned
Wonjong of Goryeo (r. 1260–1274) in 1259 on
Ganghwado. Kublai also forced two rulers of the Golden Horde and the Ilkhanate to call a truce with each other in 1270 despite the Golden Horde's interests in the Middle East and the
Caucasus. In 1260, Kublai sent one of his advisors, Hao Ching, to the court of
Emperor Lizong of Song to say that if Lizong submitted to Kublai and surrendered his dynasty, he would be granted some autonomy. Emperor Lizong refused to meet Kublai's demands and imprisoned Hao Ching and when Kublai sent a delegation to release Hao Ching, Emperor Lizong sent them back. Kublai ordered Möngke Temür to revise the second census of the Golden Horde to provide resources and men for his conquest of China. The census took place in all parts of the Golden Horde, including
Smolensk and
Vitebsk in 1274–1275. The Khans also sent
Nogai Khan to the
Balkans to strengthen Mongol influence there. Kublai renamed the Mongol regime in China Dai Yuan in 1271, and sought to sinicize his image as Emperor of China to win control of millions of Han Chinese people. When he moved his headquarters to
Khanbaliq, also called Dadu, in modern-day Beijing, there was an uprising in the old capital Karakorum that he barely contained. Kublai's actions were condemned by traditionalists and his critics still accused him of being too closely tied to Han Chinese culture. They sent a message to him: "The old customs of our Empire are not those of the Han Chinese laws ... What will happen to the old customs?" Kaidu attracted the other elites of Mongol Khanates, declaring himself to be a legitimate heir to the throne instead of Kublai, who had turned away from the ways of Genghis Khan. Defections from Kublai's dynasty swelled the Ögedeids' forces. The Song imperial family surrendered to the Yuan in 1276, making the Mongols the first non-Han Chinese people to conquer all of China. Three years later,
Yuan marines crushed the last of the Song loyalists. The Song Empress Dowager and her grandson,
Emperor Gong of Song, were then settled in
Khanbaliq where they were given tax-free property, and Kublai's wife Chabi took a personal interest in their well-being. However, Kublai later had Emperor Gong sent away to become a monk to
Zhangye. Kublai succeeded in building a powerful empire, created an academy, offices, trade ports, and canals, and sponsored science and the arts. The record of the Mongols lists 20,166 public schools created during Kublai's reign. However, Kublai's costly invasions of
Vietnam (1258),
Sakhalin (1264),
Burma (1277),
Champa (1282), and
Vietnam again (1285) secured only the
vassal status of those countries.
Mongol invasions of Japan (1274 and 1281), the
third invasion of Vietnam (1287–1288), and the
invasion of Java (1293) failed. At the same time, Kublai's nephew Ilkhan Abaqa tried to form
a grand alliance of the Mongols and the Western European powers to defeat the
Mamluks in Syria and North Africa that constantly invaded the Mongol dominions. Abaqa and Kublai focused mostly on foreign alliances and opened trade routes. Khagan Kublai dined with a large court every day and met with many ambassadors and foreign merchants. Kublai's son Nomukhan and his generals occupied
Almaliq from 1266 to 1276. In 1277, a group of Genghisid princes under Möngke's son
Shiregi rebelled, kidnapped Kublai's two sons and his general
Antong and handed them over to Kaidu and Möngke Temür. The latter was still allied with Kaidu who fashioned an alliance with him in 1269, although Möngke Temür had promised Kublai his military support to protect Kublai from the Ögedeids. When
Tekuder seized the throne of the Ilkhanate in 1282, attempting to make peace with the Mamluks, Abaqa's old Mongols under prince
Arghun appealed to Kublai. After the assassination of
Ahmad Fanakati and execution of his sons, Kublai confirmed Arghun's coronation and awarded his commander in chief
Buqa the title of
chancellor. Kublai's niece, Kelmish, who married a
Khongirad general of the Golden Horde, was powerful enough to have Kublai's sons Nomuqan and Kokhchu returned. Three leaders of the Jochids,
Tode Mongke,
Köchü, and Nogai, agreed to release two princes. The court of the Golden Horde returned the princes as a peace overture to the Yuan dynasty in 1282 and induced Kaidu to release Kublai's general. Konchi, khan of the
White Horde, established friendly relations with the Yuan and the Ilkhanate, and as a reward received luxury gifts and grain from Kublai. Despite political disagreement between contending branches of the family over the office of Khagan, the economic and commercial system continued.
Emperor of the Yuan dynasty Kublai Khan considered China his main base, realizing within a decade of his enthronement as Great Khan that he needed to concentrate on governing there. From the beginning of his reign, he adopted Chinese political and cultural models and worked to minimize the influences of regional lords, who had held immense power before and during the Song dynasty. Kublai heavily relied on his Chinese advisers until about 1276. He had many Han Chinese advisers, such as
Liu Bingzhong and
Xu Heng, and employed many Buddhist
Uyghurs, some of whom were resident commissioners running Chinese districts. Kublai also appointed the Sakya lama Drogön Chögyal Phagpa ("the Phags pa Lama") his
Imperial Preceptor, giving him power over all the empire's
Buddhist monks. In 1270, after the Phags pa Lama created the
'Phags-pa script, he was promoted to imperial preceptor. Kublai established the Supreme Control Commission under the Phags pa Lama to administer the affairs of
Tibetan and Chinese monks. During Phagspa's absence in
Tibet, the Tibetan monk Sangha rose to high office and had the office renamed the Commission for Buddhist and Tibetan Affairs. In 1286, Sangha became the dynasty's chief fiscal officer. However, their corruption later embittered Kublai, and he later relied wholly on younger Mongol aristocrats. Antong of the
Jalairs and Bayan of the Baarin served as grand councillors from 1265, and Oz-temur of the Arulad headed the
censorate. Borokhula's descendant, Ochicher, headed a
kheshig (Mongolian imperial guard) and the palace provision commission. In the eighth year of Zhiyuan (1271), Kublai officially created the Yuan dynasty and proclaimed the capital as Dadu (, known as
Khanbaliq or Daidu to the Mongols, modern Beijing) the following year. His summer capital was in
Shangdu (, also called Xanadu, near what today is
Dolon Nor). To unify China, Kublai began a massive offensive against the remnants of the
Southern Song in 1274 and finally destroyed the Song in 1279, unifying the country at last at the
Battle of Yamen where the last Song Emperor
Zhao Bing committed suicide by jumping into the sea and ending the
Song dynasty. flourished during Yuan China. Most of the Yuan domains were administered as provinces, also translated as the "Branch Secretariat", each with a governor and vice-governor. This included China proper, Manchuria, Mongolia, and a special Zhendong branch Secretariat that extended into the Korean Peninsula. The Central Region () was separate from the rest, consisting of much of present-day
North China. It was considered the most important region of the dynasty and was directly governed by the
Zhongshu Sheng at Dadu. Tibet was governed by another top-level administrative department called the
Bureau of Buddhist and Tibetan Affairs. Kublai promoted economic growth by rebuilding the
Grand Canal, repairing public buildings, and extending highways. However, his domestic policy included some aspects of the old Mongol living traditions, and as his reign continued, these traditions would clash increasingly frequently with traditional Chinese economic and social culture. Kublai decreed that partner merchants of the Mongols should be subject to taxes in 1262 and set up the Office of Market Taxes to supervise them in 1268. After the Mongol conquest of the Song, the Muslim, Uyghur, and Chinese merchants expanded their operations to the
South China Sea and the
Indian Ocean. The Mongol administration had issued paper currencies from 1227 on. In August 1260, Kublai created the first unified paper currency called
Jiaochao; bills were circulated throughout the Yuan domain with no expiration date. To guard against devaluation, the currency was convertible with silver and gold, and the government accepted tax payments in paper currency. In 1273, Kublai issued a new series of state-sponsored bills to finance his conquest of the Song, although eventually, a lack of fiscal discipline and inflation turned this move into an economic disaster. It was required to pay only in the form of paper money. To ensure its use, Kublai's government confiscated gold and silver from private citizens and foreign merchants, but traders received government-issued notes in exchange. Kublai Khan is considered to be the first
fiat money maker. The paper bills made collecting taxes and administering the empire much easier and reduced the cost of transporting coins. In 1287, Kublai's minister Sangha created a new currency, Zhiyuan Chao, to deal with a budget shortfall. It was non-convertible and denominated in
copper cash. Later
Gaykhatu of the Ilkhanate attempted to adopt the system in the Middle East, which was a complete failure, and shortly afterward he was assassinated. , and

Tranquillo Cremona, 1863 Kublai encouraged Asian arts and demonstrated religious tolerance. Despite his anti-Taoist edicts, Kublai respected the Taoist master and appointed Zhang Liushan as the patriarch of the Taoist
Xuánjiào (玄教, "Mysterious Order"). Under Zhang's advice, Taoist temples were put under the Academy of Scholarly Worthies. Several Europeans visited the empire, notably the Italian explorer
Marco Polo in the 1270s, who was appointed to serve as Khan's foreign emissary throughout the empire and lived in the emperor's lands for 17 years. During the Southern Song, the descendant of
Confucius at
Qufu,
Duke Yansheng Kong Duanyou fled south with the Song emperor to
Quzhou, while the newly established
Jin dynasty in the north appointed Kong Duanyou's brother Kong Duancao who remained in Qufu as Duke Yansheng. From that time up until the Yuan dynasty, there were two Duke Yanshengs, one in the north in Qufu and the other in the south at Quzhou. An invitation to come back to Qufu was extended to the southern Duke Yansheng Kong Zhu by the Yuan Dynasty Emperor Kublai Khan. The title was taken away from the southern branch after Kong Zhu rejected the invitation, so the northern branch of the family kept the title of Duke Yansheng. The southern branch still remained in Quzhou where they lived to this day. Confucius's descendants in Quzhou alone number 30,000. Yuan emperors like Kublai Khan forbade practices such as butchering according to Jewish (
kashrut) or Muslim (
dhabihah) legal codes and other restrictive decrees continued.
Circumcision was also strictly forbidden.

Fancheng and
Xiangyang Thirty Muslims served as high officials in the court of Kublai Khan. Eight of the dynasty's twelve administrative districts had Muslim governors appointed by Kublai Khan. Among the Muslim governors was
Sayyid Ajjal Shams al-Din Omar, who became administrator of
Yunnan. He was a well-learned man in the
Confucian and Taoist traditions and is believed to have propagated
Islam in China. Other administrators were
Nasr al-Din and
Mahmud Yalavach (mayor of the Yuan capitol). Kublai Khan patronized Muslim scholars and scientists, and Muslim astronomers contributed to the construction of the observatory in
Shaanxi. Astronomers such as
Jamal ad-Din introduced 7 new instruments and concepts that allowed the correction of the Chinese calendar. Muslim cartographers made accurate maps of all the nations along the
Silk Road and greatly influenced the knowledge of
Yuan dynasty rulers and merchants. Muslim physicians organized hospitals and had their institutes of medicine in Beijing and
Shangdu. In Beijing was the renowned
Guang Hui Si "Department of extensive mercy", where
Hui medicine and surgery were taught.
Avicenna's works were also published in China during that period. Muslim mathematicians introduced
Euclidean geometry,
spherical trigonometry, and
Arabic numerals in China. Kublai brought siege engineers
Ismail and
Al al-Din to China, and together they invented the "
Muslim trebuchet" (or
Huihui Pao), which was utilized by Kublai Khan during the
Battle of Xiangyang. ==Warfare and foreign relations==
