In the battle to suppress the Central Plains Rebel Army, the Yuan army also continued to grow and develop, and a number of outstanding emerging generals emerged, among which Chakhan Timur and Polo Timur were representatives.

Chahan Timur, a Hui people, the fourth-generation chieftain of the Turkic barbarian tribe, his great-grandfather Kuokuotai accompanied the Mongol army to Henan at the beginning of the Yuan Dynasty, and later settled in Shenqiu County, Yingzhou, Henan. The Naiban tribe was highly Mongolized because it was conquered by the Mongols earlier, and after entering the Central Plains, it was highly Sinicized, and Chahan's Han surname was Li, and he used the name Li Chahan to participate in the imperial examination, but he did not pass the examination.

Yingzhou was the starting point of the Red Turban Army uprising, and Cha rarely saw that his hometown was ruined and the imperial court was ineffective, so he led hundreds of Shenqiu's children to raise troops. He joined forces with Li Siqi, a native of Luoshan in Xinyang, and recovered Luoshan County for the imperial court, and the imperial court granted him the post of Zhongshun doctor and Daru Huachi in Runing Prefecture, and encouraged him to expand his army.

Chahan is also a representative of the pro-Yuan rebels who worked hard for the imperial court and achieved great success, which is different from those speculative pro-Yuan rebels in Jiangnan.

Chahan governed the army in a good way, bravely and strategically, defeated the Red Army many times, and his official position became bigger and bigger. During Liu Futong's Red Turban Army's three-way northern expedition, Chahan was transferred into Shaanxi to suppress the rebel army, and defeated Bai Buxin, Dadaoao, and Li Xixi's Western Route Army outside Fengxiang City, forcing them to withdraw into Sichuan. Chahan took advantage of the victory to kill Shanxi, divided troops to garrison the main roads of Taihang Mountain, and blocked the eastward way of the righteous army Mr. Guan, Potou Pan and other middle route armies, so that the righteous army could not implement the siege of the Yuan capital through Hebei, and the imperial court awarded him the right Cheng of Shaanxi Province, and the post of serving the imperial history of Shaanxi Xingtai and the privy council of Henan with the same knowledge.

Chahan killed to Henan again, defeated Liu Futong's Red Army, and captured Kaifeng, the capital of the Great Song Dynasty, the news spread to the capital, cheered up and down, Liu Futong took Han Lin'er to retreat to Baofeng, the Red Army uprising in the north turned into a trough, the imperial court issued an edict to the world for this, and sealed Chahan as the Pingzhang political affairs of Henan Province, and also knew the Privy Council of Henan, Shaanxi Xingtai Imperial History Zhongcheng, and acted cheaply.

Although the imperial court repeatedly gave Chahan official titles, it was limited to Henan and Shaanxi, because the imperial court also wanted to prevent Chahan from threatening the imperial power. For the two strategic places of Shanxi and Hebei, the imperial court meant to put Polo Timur in charge.

Polo Timur, Mongolian, after the uprising of the Red Turban Army, Polo's father replied to lose Badulu as Pingzhang of Henan Province, and was the main opponent of the righteous army, Polo followed his father to fight in the Central Plains, Liu Futong attacked and lost Badulu in Zhongmu, captured Polo, fortunately another general Liu Hara Buhua defeated Liu Futong, rescued Polo, and reunited their father and son.

Answer: Badulu died of grief, and Polo succeeded his father as the coach. In the war against the Northern Expeditionary Army, he fought mainly on the Eastern Front, winning a number of key battles.

Polo defeated the rebels at Weihui, and then conquered Puzhou, preventing the rebels from going north from Henan to Hebei to cooperate with Mao Gui to attack Dadu, so that Mao Gui's lone army was forced to retreat to Shandong. Polo drove south to defeat Sha Liu and other rebels in Pengcheng, opening up the connection with Lianghuai. He also attacked Caozhou and cut off the connection between Kaifeng and Shandong. The Shanxi rebels captured Shangdu and threatened Dadu from the north, and the Yuan Dynasty transferred Polo into Shanxi and appointed him as the governor of Datong, and Polo defeated Mr. Guan and drove him out of Shanxi that month.

After Polo came to Shanxi, there was a conflict with Chahan, earlier Chahan made great contributions to pacify Shanxi, but the imperial court handed over Shanxi to Polo, which made Chahan very dissatisfied, but he could not do anything to the central government, he could only spread his anger on Polo's body, Chahan and Polo fought, and the imperial court issued several edicts to stop it, but Chahan ignored it.

The reason why the imperial court handed over Shanxi and Hebei to Luo Polo was considered, Polo was a Mongol, Chahan was a Semu person, Polo was a regular soldier of the imperial court, Chahan started from a cottage, and most importantly, Polo's daughter married Emperor Yuan Shun, and he himself jumped to become the ruler of the country, whether from the perspective of blood relations or political reliability, the imperial court had reason to favor Polo, so Shanxi and Hebei, which were closer to the capital, were handed over to Polo, and the surrounding Shaanxi and Henan were handed over to Chahan.

This partiality led to Chahan's dissatisfaction, he ignored the orders of the imperial court, appointed officials and mobilized troops without authorization, waited for the mechanism to subdue Polo and expand his own huge military machine, the friction between the two sides interrupted the process of the Yuan army's suppression of the rebel army, so that the Jiangbei rebel army got a chance to breathe, but also created conditions for the Jiangnan rebel army to continue to bite each other, during this period Zhu Yuanzhang and Chen Youliang fought for the right to control the river in Jiangxi Province and the upper reaches of the Yangtze River.

Fortunately, Chahan did not completely abandon his duties, just when the Yuan army was in dispute, the Shandong Righteous Army also had serious infighting, and Mao Gui, the leader of the Shandong Righteous Army, was murdered by Zhao Junyong, and Mao Gui's subordinate Jizu killed Zhao Junyong, which seriously weakened the strength of the Righteous Army.

Hearing this, Chahan decided to stop attacking Polo and began to attack Shandong, Chahan led all walks of life, with his adopted son Kuangku Timur as the vanguard and marched eastward, Chahan fought and pacified, and the military operation progressed rapidly, and in the second year he recovered the entire territory of Shandong except Yidu.

The strategic location of Shandong is very important, not only controlling the economic lifeline of the canal, but also the rebel army can march along the canal at any time to overthrow the Yuan government, it can be said that as long as the rebel army controls Shandong, the Yuan capital will always be within the range of the rebel army. Once the capital of Yuan is captured, the sparks of the stars across the country will ignite a raging flame, burning the Great Yuan to ashes.

Therefore, the significance of Chahan's recovery of Shandong is very significant, and the imperial court sealed Chahan as the political affairs of Zhongshu Pingzhang, the Privy Council of Henan and Shandong, and the Taichung Cheng of Shaanxi.

However, the rebels were not willing to lose, and Chen Yutou, who insisted on resisting in Yidu, contacted Tian Feng and Wang Shicheng, who had surrendered to the Yuan army, and plotted to assassinate Chahan. Tian Feng and Wang Shicheng were originally generals of the Yuan Army, responsible for the defense of Shandong, and when the Red Turban Army swept through Shandong, they surrendered to the Red Army.

Considering that Tian Feng had been running Shandong for a long time and enjoyed a certain prestige among the military and civilians, Chahan suggested that the imperial court pardon Tian Feng's crimes and surrender him, so as to speed up military progress and better maintain the stability of Shandong. At the same time, Chahan wrote a letter of persuasion to Tian Feng, asking him to change his ways, return to the arms of the imperial court, and serve the imperial court to pacify Shandong. In the face of huge military pressure, Tian Feng surrendered reluctantly, and Wang Shicheng also surrendered.

Chahan was convinced of the two of them, treated them sincerely, and entered Tian Feng's camp alone several times, but Tian Feng's deferential appearance had a volatile heart, in his opinion, the Yuan army was rotten, as long as Chahan died, it was easy to overthrow the Yuan Dynasty. Chen Yutou discussed with Tian Feng and Wang Shicheng, and assassinated Chahan when he came to inspect the army again.

After the agreement, Tian Feng invited Chahan to the camp to discuss military affairs, and Chahan's subordinates advised him not to go, but he didn't care, and said: "I treat people with my heart, how can I guard against everyone?"

His subordinates persuaded him to bring more guards, but Chahan did not allow it, and only brought eleven personal guards, but was assassinated by Wang Shicheng in Tianfeng's camp. Chahan's death is a major event that rewrites history, after his death, the Yuan army has no leader, the combat effectiveness is seriously weakened, and it is mired in internal strife and cannot extricate itself, if Chahan does not die, it will cause great trouble to Zhu Yuanzhang to overthrow the Yuan Dynasty, and history is likely to be rewritten.

It is said that before Chahan's death, there was a white light like a rope, more than 500 zhang long, rising from the Pleiades and sweeping over the Taiwei Wall. The officials thought that Shandong might be flooded, but Emperor Yuan said: "Otherwise, Shandong will lose a good general." ”

He immediately sent men to Shandong to warn Timur not to act rashly, but before the messenger arrived, Chakhan was already dead. When the news of Chahan's death reached Jingcheng, the officials of the DPRK and China and the people of the capital, men, women and children, wept uncontrollably.

After Chahan's death, the court gave him a series of rewards and nicknames, and appointed his nephew and adopted son, Kokor Timur, to succeed him.

Kuokuo, Hui, formerly known as Wang Baobao, is the son of Chahan's sister and a Han surnamed Wang, because Chahan has no heirs, Wang Baobao was passed on to Chahan as a son, or he was originally a Han and was adopted as an adopted son by Chahan. When he was ordered to deliver grain to Dadu, Emperor Yuan Shun met him and gave him the Mongolian name Kuokhor Timur.

The first thing after taking office was to avenge Chahan, Tian Feng and Wang Shicheng assassinated Chahan and fled to Yidu Chen Yutou, Kuangkuo mourned to please the thief, the siege of the city was urgent, the defenders of the city resisted desperately, the Yuan army used the method of digging tunnels to attack the city, captured Chen Yutou, Tian Feng, Wang Shicheng and others alive, and Guangkuo escorted more than 200 people such as Chen Yutou to the capital to offer prisoners, and executed Tian Feng and Wang Shicheng by himself, he dug out the hearts of the two to pay tribute to the dead of Chahan.

After leveling Shandong, the division was stationed in Kaifeng and Luoyang, and the entire northern Haiqing River weir was peaceful, and the imperial court was peaceful, but infighting ensued, and Polo took advantage of Chahan's death to expand his sphere of influence, and sent troops to fight for Shanxi and Hebei, and the two fought inseparably.

Polo also provoked a court struggle, he wanted to replace the crown prince Aiyu Darila, because the latter was not born to his empress daughter, but to one of Emperor Shun's favorite concubines, and he recruited Emperor Yuan Shun's uncle, the imperial historian Lao Sha, and the privy councillor Baljian Timur to participate in the plot.

The crown prince wanted to kill Lao Sha and Vuljian Timur, and the two fled to Datong to seek refuge in Polo. The prince refused to give up, he had to be poor, the prime minister and the eunuch Pu Buhua reported Polo and the old Sha plotter, Emperor Yuan Shun was forced to cut all the official positions of Polo under pressure, Polo was furious, and invaded the Jingshi in the name of the Qing monarch's side, and Emperor Yuan Shun had no choice but to hand over the Sijian and Pu Buhua to Polo for disposal, and Polo did not stop after killing the two, and continued to commit crimes.

The prince was in a hurry to turn to the expansion of the knot, the expansion of the general general white lock with 10,000 cavalry rescue, but was defeated, Luo Xiao led the army into the capital, self-proclaimed prime minister, the power of the court into the hands, the prince fled to Taiyuan to join the expansion.

The crown prince and the expansion of the army counterattack, they first captured Datong, the old nest of Polo, and then attacked the Jingshi, Emperor Yuan Shun then decided to abandon Polo, on the way to the court, Polo was hacked to death with an axe, Emperor Yuan Shun put his head into a box, sent someone to the prince, and said that the prince was welcome to return to the capital. Kuokuo and the prince entered the court together, and Emperor Yuan Shun sealed the kuokuo as the prince and the left prime minister.

After the expansion of the Kuo and the elimination of Polo, the infighting in the Yuan court not only did not end, but set off a new high. Although the credit for expanding the outline is great, after all, the qualifications are shallow, from a little-known small person suddenly became a prime minister, a very popular minister, which caused many old cadres to be dissatisfied, and he himself was not interested in palace politics, and he was unwilling to give up military power, and asked to go out to lead the army.

Soon after Zhu Yuanzhang eliminated Chen Youliang, Emperor Yuan Shun made him the king of Henan and ordered him to lead the world's soldiers and horses and go to Jiangnan on behalf of the crown prince. At this time, the Yuan army was strong and strong, if nothing else, it would cause great trouble to Zhu Yuanzhang, but at this critical time, the Yuan army had internal strife.

After Kuangkuo led the army into Henan, he ordered Li Siqi, Zhang Liangbi, Kong Xing, and Tolebo troops stationed in Guanzhong to come to join the division, and when Li Siqi got the order to transfer troops from Kuangkuo, Li Siqi scolded: "When I was dating your father, your fetal hair had not dried yet, how dare you give me an order?" He ordered that not a single soldier should be allowed to leave the customs.

Li Siqi and the father of the expansion of the army Chahan at the same time in Henan, fighting side by side, the two of them are the same age, official position, fame, as a meritorious senior, it is difficult to obey the command of the rich second generation of the expansion of the outline, Zhang Liangbi, Trebo and Kong Xing were Polo's comrades-in-arms, and they did not want to be subordinate to the expansion of the outline, they all refused the transfer of the expansion.

He said angrily: "I am ordered to lead the soldiers and horses of the world, and the town will not be controlled, what kind of thief do you want?"

So he sent his younger brother Toyin Timur to garrison Jinan, Shandong with a team of men and horses, to prevent the righteous army from attacking Dadu through Shandong along the canal, and personally led the army into the pass to attack Li Siqi and others.

After Li Siqi and others learned the news, they met with troops and swore to work together to resist the expansion, and the two sides held each other for a year, fought hundreds of battles, and did not distinguish the winner or loser. Zhu Yuanzhang took this opportunity to eliminate Zhang Shicheng, and there was a great tendency to unify Jiangnan, and Emperor Yuan Shun hurriedly sent an edict to Kuangkuo, ordering him to stop the civil war and attack the Jiangnan Righteous Army, but Kuangkuo had been carried away by the civil war, and insisted on pacifying Li Siqi and others first, and then sending troops to Jiangnan.

In order to end the civil war as soon as possible, the expansion of the general Gao led the army to raid Fengxiang, in an attempt to overturn Li Siqi's lair, Gao is the old general of Chahan, outstanding achievements, seniority, he and Li Siqi are not satisfied with the expansion, and most of his subordinates are the old Polo department, but also dissatisfied with the expansion, when the troops to Wei Hui, the troops mutinied, Gao betrayed the expansion, he led the troops to attack Wei Hui, Zhangde, and wrote to the court to expose the crime of expansion.

Emperor Yuan Shun made three decisions: he stripped him of the posts of the Taifu of Kuangkuo and the prime minister of Zhongshu Zuo, and ordered him to serve as the king of Henan and hand over the troops to other generals; he was awarded the Privy Council of Kochi and the Pingzhang, who was in charge of the Hebei army and gave him the military title of Loyal and Righteous Meritorious Hero; and the crown prince opened the Fujun Academy in Dadu to control the soldiers and horses of the world and prepare for the expansion.

After being punished by the imperial court, Kuangkuo was disheartened and retreated to Zezhou, at this time another important general Guan Bao led the army to flee, as Chahan's old subordinates, he betrayed the Kuangkuo for the same reason as Gao, the court saw this and thought that the Kuangkuo soldiers were lonely, weak and bullied, so they ordered Li Siqi and others to send troops to Shaanxi, and Gao Gao to attack and expand, and at the same time ordered Guan Bao to defend Taiyuan.

At this point, the expansion of the country from the savior of the country to the enemy of the people, the court not only abandoned him, but also put him to death, the expansion of the resistance to the army, sent troops to attack Taiyuan, and killed all the officials of the court in Taiyuan, Emperor Shun was furious, issued an edict to cut down the officials of the expansion, so that the armies were on all sides.
