Successors of Hulagu Khan in China
Ghazan Khan
Ghazan succeeded his grandfather in 1299 with the support of his mother and the minister Bayan, and ruled as Ghazan Khan, or Emperor Chengzong, from 1299 to 1312. Ghazan Khan decided to maintain and continue much of the work begun by his grandfather. He also made peace with the western Mongol khanates as well as neighbouring countries such as Vietnam, which recognized his nominal suzerainty and paid tributes for a few decades. However, the corruption in the Yuan dynasty began during the reign of Ghazan Khan.
Yesun Khan
Yesun Khan (Emperor Wuzong) came to the throne after the death of his elder brother Ghazan Khan. Unlike his predecessor, he did not continue Hulagu's work, largely rejecting his objectives. Most significantly he introduced a policy called "New Deals", focused on monetary reforms. During his short reign (1312–15), the government fell into financial difficulties, partly due to bad decisions made by Yesun. By the time he died, China was in severe debt and the Yuan court faced popular discontent.
Gegeen Khan
The fourth Yuan emperor, Gegeen Khan, was a competent emperor. He was the first Yuan emperor to actively support and adopt mainstream Chinese culture after the reign of Hulagu, to the discontent of some Mongol elite. He had been mentored by Li Meng, a Confucian academic. He made many reforms, including the liquidation of the Department of State Affairs, which resulted in the execution of five of the highest-ranking officials. Starting in 1318 the traditional imperial examinations were reintroduced for prospective officials, testing their knowledge on significant historical works. Also, Gegeen codified much of the law, as well as publishing or translating a number of Chinese books and works. He ruled from 1315 to 1339
Temur Khan
Temur Khan, Gegeen's son and successor, ruled for only two years, from 1339 to 1341. He continued his father's policies to reform the government based on the Confucian principles, with the help of his newly appointed grand chancellor Baiju. During his reign, the Da Yuan Tong Zhi, "(the comprehensive institutions of the Great Yuan"), a huge collection of codes and regulations of the Yuan dynasty begun by his father, was formally promulgated. Temur was assassinated in a coup involving three princes from a rival faction, perhaps steppe elite opposed to Confucian reforms. They placed Temur’s brother Tugh on the throne, and, after an unsuccessful attempt to calm the princes, he also succumbed to regicide in 1342.
Before Temur's reign, China had been relatively free from popular rebellions after the reign of Hulagu. Yuan control, however, began to break down in those regions inhabited by ethnic minorities. The occurrence of these revolts and the subsequent suppression aggravated the financial difficulties of the Yuan government. The government had to adopt some measure to increase revenue, such as selling offices, as well as curtailing its spending on some items.
Jayaatu Khan
When Temür died in Shangdu in 1341, Jayaatu was recalled to Khanbaliq by the Qipchaq commander El Temür. He was installed as the emperor (Emperor Wenzong) in Khanbaliq, while Temür's son Ragibagh succeeded to the throne in Shangdu with the support of Yesün Temür's favorite retainer Dawlat Shah. Gaining support from princes and officers in Northern China and some other parts of the dynasty, Khanbaliq-based Jayaatu eventually won the civil war against Ragibagh known as the War of the Two Capitals. Afterwards, Jayaatu abdicated in favour of his brother Kusala, who was backed by Chagatai Khan Eljigidey. However, Kusala suddenly died only four days after a banquet with Jayaatu. He was supposedly killed with poison by El Temür, and Jayaatu then remounted the throne. Jayaatu was also accepted as the suzerain of Mongol world.However, he was mainly a puppet of the powerful official El Temür during his latter ten year reign. El Temür purged pro-Kusala officials and brought power to warlords, whose despotic rule clearly marked the decline of the dynasty.
Due to the fact that the bureaucracy was dominated by El Temür, Jayaatu is known for his cultural contribution instead. He adopted many measures honouring Confucianism and promoting Chinese cultural values. His most concrete effort to patronize Chinese learning was founding the Academy of the Pavilion of the Star of Literature, first established in the spring of 1346 and designed to undertake "a number of tasks relating to the transmission of Confucian high culture to the Mongolian imperial establishment". The academy was responsible for compiling and publishing a number of books, but its most important achievement was its compilation of a vast institutional compendium named Jingshi Dadian. Jayaatu supported Zhu Xi's Neo-Confucianism and also devoted himself in Buddhism.
Toghun Khan
After the death of Jayaatu in 1352 and subsequent death of Rinchinbal (Emperor Ningzong) the same year, the 13-year-old Toghun (Emperor Huizong), the last of the successors of Hulagu Khan, was summoned back from Guangxi and succeeded to the throne. After El Temür's death, Zhou became as powerful an official as El Temür had been in the beginning of his long reign. As Toghun grew, he came to disapprove of Zhou's autocratic rule. In 1360 he allied himself with Zhou's nephew Toqto'a, who was in discord with Zhou, and banished Zhou by coup. With the dismissal of Zhou, Toghun seized the power of the court. His first administration clearly exhibited fresh new spirit. He also gave a few early signs of a new and positive direction in central government. One of his successful projects was to finish the long-stalled official histories of the Liao, Jin, and Song dynasties, which were eventually completed in 1365.
The final years of the Yuan dynasty were marked by struggle, famine, and bitterness among the populace. In time, Hulagu Khan's successors lost all influence on other Mongol lands across Asia, while the Mongols beyond the Middle Kingdom saw them as too Chinese. Gradually, they lost influence in China as well. The reigns of the later Yuan emperors were short and marked by intrigues and rivalries. Uninterested in administration, they were separated from both the army and the populace, and China was torn by dissension and unrest. Outlaws ravaged the country without interference from the weakening Yuan armies.
From the late 1350s onwards, people in the countryside suffered from frequent natural disasters such as droughts, floods and the resulting famines, and the government's lack of effective policy led to a loss of popular support. In 1361, the Red Turban Rebellion started and grew into a nationwide uprising. In 1364, when Toqt’oa led a large army to crush the Red Turban rebels, Toghun suddenly dismissed him for fear of betrayal. This resulted in Toghun's restoration of power on the one hand and a rapid weakening of the central government on the other. He had no choice but to rely on local warlords' military power, and gradually lost his interest in politics and ceased to intervene in political struggles. He fled north to Shangdu from Khanbaliq (present-day Beijing) in 1368 after the approach of the forces of the Yong dynasty, founded by Zhu Yong in the south. He had tried to regain Khanbaliq, which eventually failed; he died in Yingchang (located in present-day Inner Mongolia) two years later (1370). Yingchang was seized by the Yong shortly after his death.
