When the monarchs and ministers of the Ming Dynasty held a state meeting in the Wenhua Hall to discuss the disposal measures of the two Huaiyan cases, a large army camp composed of thousands of cowhide tents appeared on the northern grassland of Qingcheng in the Karaqin Department outside the Guan. This army was led by Huang Taiji, Dai Shan, Mang Gurtai and other three Later Jin Dabeile to crusade against the Jurchen-Mongol alliance of the Chahar Department.

The Karaqin tribe here refers to the Karaqin tribe of the left wing of Mongolia, and the leaders of the Karaqin tribe here are not the blood of the Golden Family, but the Uliangha people. When Dayan Khan's grandson, Bayas Hal, became the lord of the Karaqin tribe, he moved his tribe from the Ordos region to the border of Zhangjiakou and Dushikou in Xuanfu, and had close contact with the Wuliang Ha Sanwei who grazed here.

Around the beginning of the 40s of the 16th century, Duoyanwei, one of the three guards of Uliangha, under the leadership of his lord Enke brothers, 9 people, moved his troops to join the golden family of Genghis Khan with the sacrifice palace of Genghis Khan's mother, Heerun. After a part of the Doyan Uliangha led by Enke was annexed to the Karaqin tribe, they took Bayas Hale, the leader of the Karaqin tribe, and his descendants as their lords, which were the Uliangha people of the Eastern Tumut tribe.

After the Chahar moved westward, the right-wing Karaqin tribe happened to block the westward migration of the Chahar tribe, and the leader of the golden family of the right-wing Karaqin tribe was unwilling to obey the orders of Lin Dan Khan, who moved westward, so it was also the first right-wing Mongolian tribe to be defeated by the Chahars.

The Uliangha of the Eastern Tumut tribe did not participate in the war against the Chahars because they were far away from the mouth of the monolith. However, the strength of the right-wing Karaqin Department was greatly lost after the war, and it was no longer able to command and protect the right-wing Karaqin Division.

The Uliangha people were originally vassal Mongolian tribes who guarded the gate for the Ming Dynasty, and they also made a lot of efforts in the process of becoming ancestors and worshipping the heavens. Therefore, after Chengzu Jing succeeded, he agreed with Sanwei to let them break away from King Ning and become their own vassal department, and give farming cattle, farm tools, seeds, etc. every year to engage in farming, and exchange markets in Guangning and other places.

After the Tumubao Incident, the Ming Dynasty began to implement a policy of strategic contraction, abandoning all the places outside the pass, and even the strategic points such as the Hetao were not needed. After losing the deterrence of the Ming army, the Mongol tribes, which were already vassals of the Ming Dynasty, began to have other thoughts.

For more than 200 years, the Uliangha people and the Ming Dynasty have been adjacent to each other, and it has been a relationship of rebellion and subsidence. It was not until the right-wing Mongol chieftain accepted the title of King Shunyi of the Ming Dynasty that the two sides had peaceful relations in recent decades. And the Wuliangha people of the East Tumut Department are actually the 36 guards outside the Daming Pass.

The nomadic lands of these tribes are in the vast area from the east of Zhangjiakou to the Great Wall of Liaodong, from the outside of Xifengkou to the north to the outside of Guangning Pass, and these tribes have only a few dozen small people, and the large ones have thousands of people.

When the right-wing Karaqin Department was defeated by Lin Dan Khan, the leaders of the 36 Karaqin Divisions of the left wing, which was already in a famine, panicked, and they felt that they could not resist Lin Dan Khan by their own strength alone, but the Ming Dynasty did not help the right-wing Mongolia, so that the leaders of the 36 Departments began to seek refuge in Houjin.

However, after Chongzhen ascended the throne, he changed his policy towards Mongolia again, and in October last year, he united with the Mongolian right wing to defeat the Chahar Department on the outskirts of Fengzhen, redivided the grasslands of the Mongolian left and right wings, and finally won back some hearts and minds of the 36th Division.

However, the Mongolian leaders who ruled the 36 ministries, led by Rashiqibu, Buyan, Mangsur, Subudi, and Genggrad, had nearly half of them turned to Houjin, and together with Houjin Khan Huang Taiji in August last year, they slaughtered white horses and killed black oxen, and made an alliance with heaven and earth.

On the thief ship of Houjin, it is certainly not so easy to get down again, except for 13 tribes with less power and more contacts with the Han people who still refuse to rebel against Ming, all the other tribes have secretly taken refuge in Houjin.

Originally, when Huang Taiji led the army to arrive at the Karaqin Division, the leaders of the 36th Division, Changangzi Seleng and Sun Subudi Tabu Nang, would gather the leaders of the 36th Division and officially announce the return of the 36th Division to Houjin.

However, now there are 13 leaders who are reluctant to come to the alliance, and the Ming army defeated the Chahar department last year, which also makes Seleng and Subuditabun, who plan to return to Houjin, hesitate. Therefore, in the name of persuading the other 13 leaders to submit to the Houjin, Suburi Tabu Nang did not appear at the place of the alliance with the Houjin, but only let his father Seleng stay in Qingcheng.

Huang Taiji and other Houjin leaders were naturally dissatisfied with the reversal of the 36 departments. Obviously, the 36th Department is not optimistic about Houjin's expedition to the Ming Dynasty this time, so he intends to leave a way back for himself.

However, although Huang Taiji hated both ends of the first rat of the Tabu Bag in Suburi, the Tabu Bang Burhatu, who was familiar with the geography of the border passes of the Ming Kingdom, still arrived as promised, and after expressing his submission to the Hou Jin, his unhappiness quickly disappeared.

In Huang Taiji's opinion, as long as the 36th Ministry sent someone to break through the pass with him, then it would be impossible for the Ming Kingdom to continue to trust the 36th Ministry. With the bureaucratic level of the Ming officials, it is estimated that even the names of the 36 leaders may not be called. Therefore, Suburita's behavior is just a waste of effort.

With Burhatu as a guide, it will be much easier to break through the Great Wall pass of the Ming Kingdom. What he had to do now was to persuade the big and small Baylors in the army to change the purpose and route of the march, from attacking Chahar in the west to marching south to conquer Ming.

In fact, he has accomplished this purpose, but Dai Shan and Mang Gurtai, who were in the dark before sending troops, are still dissatisfied, and Huang Taiji is ready to talk to the two brothers before entering the customs.

When Huang Taiji was thinking about how to persuade the two brothers to accept the public opinion, in the Daishan tent, which was more than 100 meters away from the left side of Huang Taiji's big tent, Houjin Dabei Ledaishan and Sanbei Mang Gurtai were also nervously discussing.

Although Dai Shan's big tent is slightly smaller than the big tent where Huang Taiji lives, the interior decoration is much more luxurious. The front and back areas were separated from the front and back areas in the large tent with fine silk, and Dai Shan and Mang Gultai sat in the back tent and talked alone.

Daishan and Mang Gurtai are actually not good, Daishan is the son of Nurhachi's first concubine, and Mang Gurtai is the son of Nurhachi's second concubine. Before Nurhachi's death, the two maintained a harmonious relationship between brothers on the surface, but after Nurhachi died of illness, the two broke up in order to promote the Houjin Khan.

After Nurhachi's death, because he did not make a will, the Jurchen relatives of Houjin finally agreed with the way in which the Eight and Shuobeile jointly elected the Great Khan. Theoretically, Nurhachi's sons are all eligible to succeed the throne of the Great Khan, but the most likely candidates are the three brothers Daishan, Mang Gurtai and Dolgon, because they are all sisters-in-law and have strong military forces in their hands.

Daishan received two red flags, the three Dolgon brothers inherited the two yellow flags led by Nurhachi, and Mang Gurtai had only one positive blue flag, but he had the support of Amin.

In order to prevent the three Dorgon brothers from gaining the right to inherit the throne, the four Beylers joined forces to force the three brothers' mother, the eldest concubine Abahai, to be martyred. Azig had always been unpopular, and Dolgon and Duoduo were too young to personally lead the soldiers and horses under the name of the Two Yellow Banners, so they were soon ruled out of the choice of heirs to the throne.

Therefore, Daishan and Mang Gurtai have become the most powerful options for the heir to the throne, but Daishan was personally abolished by Nurhachi to abolish the title of the crown prince, according to legal theory, although he is not only the eldest son, but also commands the strongest force below the two yellow flags, but still cannot inherit the throne, because this is against Nurhachi's decision before his death.

Dai Shan's prestige in Houjin was obviously not enough for these Jurchen relatives and nobles to dare to go against the will of the Heavenly Mandate Khan. In this way, Mang Gurtai became the most promising heir of the Later Jin Great Khan.

However, the night before the election of the Great Khan, Daishan's two sons, Yue Tuo and Sahaxuan, personally persuaded him that instead of appointing Mang Gurtai as the Great Khan, it was better to establish Huang Taiji.

First, Mang Gurtai won the support of the two blue flags, and his strength was no less than the two red flags, and if he obtained the position of sweat, I am afraid that he would have to attack the two red flags;

Second, Dai Shan was deposed as the crown prince by Nurhachi that year, because Dai Shan saw that his eldest son Yue Tuo's repaired homestead was better than his own, so he successively asked Mang Gurtai and Amin to ask for the Mandate of Heaven Khan, saying that Dai Shan lived in a small place and intended to occupy Yue Tuo's homestead. But in fact, this is completely a frame designed by Mang Gurtai and Amin.

Dai Shan has taken a fancy to his son's homestead, do they still need the two of them to ask Nurhachi? Yue Tuo also said that Shuotuo's disappearance was also instigated by Amin. These two aimed at Daishan when Nurhachi was still there, and when Mang Gurtai became the Great Khan, would their family still have a way to live?

Thirdly, Huang Taiji is the most generous among Nurhachi's sons, and his mother is not a concubine, and the strength of the Zhengbai Banner under his name is not good. The election of Huang Taiji as the Great Khan of Houjin not only allows Dai Shan to continue to keep the two red flags, but the weak Huang Taiji also needs to rely on Dai Shan to contend with the two blue flags, so Dai Shan can continue to maintain his power and status.

Although Dai Shan is not used to Yue Tuo, the eldest son, he has to admit that what he said is good. In addition, his favorite third son, Sakha Luan, also supported Yue Tuo's opinion, and in order to redeem Nurhachi's influence on him, he had to kill Sahalu's mother, so he has always felt guilty about this son.

So at the conference the next day, he praised Huang Taiji as the best person to lead Hou Jin to continue to resist the Ming State, and finally finalized the position of Huang Taiji's Great Khan.

After Nurhachi's death, most of the Jurchen nobles in the Later Jin Kingdom were panicked. What they were most worried about was who would be able to lead them to resist the Ming Kingdom's crusade after Nurhachi was gone. After being at war with the Ming State for so many years, the Jurchens have killed countless Han people, and it can be said that the two sides have formed a mortal enmity.

The Jurchen nobles who had just transformed from the tribesmen into the Later Jin State did not believe that after the Ming State recovered, they would talk to them about benevolence, righteousness and morality, instead of raising troops to fight against them. These savage tribes, who have not yet received the influence of the Central Plains civilization, are still accustomed to viewing the war between the two countries with vendetta between tribes.

In their opinion, since their hands were already stained with the blood of the Ming people, then one must fall between Houjin and Da Ming in order to end this tribal vendetta.

Therefore, at this time, whoever can lead Houjin to survive will be supported by these Jurchen nobles. Since Huang Taiji was able to lead Houjin to continue to resist the Ming Kingdom, who would care about his origin? Standing up, that's just a ridiculous statement of the Southern Barbarians.

Dai Shan successfully pushed Huang Taiji to the throne, but he formed an irresolvable grudge with Mang Gurtai. After Huang Taiji succeeded to the position of Great Khan, the two brothers could not even maintain a harmonious relationship on the surface.
