In fact, with the fall of the Northern Yuan Dynasty, the Mongol Empire had already come to an end, when Emperor Taizu set the Central Plains and expelled the Northern Yuan lineage from the Guanwai, representing the glory of the Golden Family, the Son Jin clan lost its supremacy among the Tatars.

And the first to rise up against the rule of the Erjin clan was Gui Lichi, the leader of the Qi'er Jisi tribe, who denied the legitimacy of the rule of the Erjin clan, and killed the last emperor of the Northern Yuan Dynasty, Erleboke, in the first year of Jianwen, and called himself Khan!

But it is a pity that although Guilichi ended the Northern Yuan, but his khanate was not recognized by other tribes, but was attacked by a group, in the second year of Guilichi killing Erleboke, Guilichi was overthrown by the two coalition forces of the Asut Department and the Oirat Department, and more importantly, these two tribes are not like other tribes, bent on trying to take the throne, they immediately expressed their submission to the Ming Dynasty after killing Guilichi.

With the support of the Ming Dynasty, the Asuth and Oirat tribes quickly rose to become the two most powerful tribes among the Mongol tribes.

At the same time, in the first year of Yongle, Benjamli, the son of Elberk, reassembled an army, claiming to be the descendants of the Golden Family, the rightful ruler of the Mongol Empire, and quickly subdued all the tribes, including the Asut tribe, except for the Oirat tribe, which was still struggling to hold on.

And at this time, it was the second year of the success of Emperor Chengzu, after learning of this, Emperor Chengzu sent a mission to submit to Benya, but Benjamin was proud of his power, and blatantly refused to surrender, so in the eighth year of Yongle, Emperor Chengzu personally led a large army into the hinterland of Mongolia to help the Oirat Department defeat Benjamin's army.

From then on, the Golden Family's Sons and Sons were in complete decline, and the Mongol rule was transferred from the Golden Family to the Oirats of the Oirats.

But in fact, although Benyasuri was defeated, he did not die, and he fled to the Korqin tribe with the leader of the Asut tribe, Arutai, but was betrayed by Arutai, the leader of the Korqin tribe, Atai, who took over the remnants of Benyasuri and Arutai, and then killed Benyasuri with the help of Arutai.

Korqin is a descendant of Genghis Khan's younger brother Hazar, although not a direct line, but also has the blood of the Golden Family.

In order to weaken the influence of the Golden Family, Emperor Chengzu at that time chose the Oirat tribe among the two forces, so after decades of war, the leader of the Oirat tribe, Mahamu, killed Atai, truly became the leader of the Mongols, and turned the Mongols into a thorn.

After the Oirat Department obtained the Khan throne, perhaps because Emperor Chengzu impressed them too deeply, so they did not rush to turn their faces with the Ming Dynasty, but chose to march to the Chagatai Khanate in the southeast, after decades of efforts, the leader of the Oirat Department also changed for several generations, and became a young man named Yexian, in the Yexian generation, Oirat finally defeated the Weisi Khan of the Chagatai Khanate, and forcibly married the sister of Weisi Khan, Princess Hanim.

The Chagatai Khanate is also a branch of the Golden Family, so it also married Princess Hanim first, so that the Oirat Department also has the blood of the Golden Family, and since then it has legitimacy in bloodline!

Solving the biggest threat to himself, legitimacy, the Oirat Department finally freed up his hands and stretched out his claws to Daming!

In the fourteenth year of orthodoxy, he also first asked Emperor Yingzong to marry a Chinese princess and was refused, and brazenly sent troops to Shanxi to attack the military town of Datong.

The Ming Dynasty was defeated, and Emperor Yingzong was captured in the North Hunt!

At the critical moment, Yu Qian, the secretary of the military department, came forward to stabilize the overall situation, supported Emperor Jingtai to succeed to the throne, and refused to be outside the city gate.

After a few days of confrontation between the two sides, the reinforcements transferred by the Ming Dynasty from all over the country rushed to Beijing, and they had no choice but to retreat, which was the famous Tumubao Change.

After retiring first, he was unwilling and decided to release Emperor Yingzong, causing chaos within the Ming Dynasty, so he sent an envoy to negotiate peace with the Ming Dynasty, returned Emperor Yingzong, and declared himself a vassal of the Ming Dynasty.

Later, Emperor Yingzong returned to Beijing, and after being imprisoned for decades, he finally launched a change to seize the door, and re-ascended the throne without mentioning, it should be said that the conspiracy of Yexian was indeed successful, and the Ming Dynasty did set off a bloody storm because of his behavior of returning Emperor Yingzong.

But there are pros and cons, and this decision is also the biggest wrong decision he has made in his life!

In order to smoothly return Emperor Yingzong, he also declared himself a vassal of the Ming Dynasty, which caused strong dissatisfaction among other Mongolian tribes, and because of this incident, the Oirat tribe, which had been sitting on the Mongolian throne because of the golden family bloodline, was once again questioned about the legitimacy of its rule.

In the sixth year of Jingtai, he was defeated and killed among the tribes, and in the same year, his son Amasang Chitaiji inherited the throne, but at this time, Yexian's wife, who was also the princess of the Chagatai Khanate, who he had forcibly married, launched a rebellion, although it was not successful, but after this civil strife, the power of the Oirats was greatly weakened.

After the decline of the Oirat Department, the Golden Family was defeated by the Oirat Department and rose again, and the twenty-eighth generation descendant of Genghis Khan, Dayan Khan, succeeded to the throne in the fourth year of Chenghua, and completely defeated the Oirat Department and drove it out of the central and eastern part of Mongolia.

However, although the Oirat tribe was defeated, it did not disappear, but withdrew from the capital city of Hala Horin, which symbolized the Mongol khanate, and led his tribes to migrate to the west.

After regaining the throne of the Khan, Dayan Khan did not continue to pursue the Oirath tribe, because his foundation was not stable, and during the decades of his rule, he first suppressed the Tumut and Uliangha tribes who intended to rebel, and then continued to drive the Oirat tribe farther away, completely cutting off the connection between Oirat and the Ming Dynasty, and firmly established his position as the Great Khan of Mongolia.

Therefore, the Mongolia now called by the Ming Dynasty is actually divided into two parts, one is the Oirat Mongolia, that is, the Wasang, and the other is the Mongolia led by the Chahar Department established by Dayan Khan, that is, the Tatars.

However, although Dayan Khan is a majestic monarch, but his descendants are not as capable as him, after the death of Dayan Khan, the Chahar tribe gradually lost the ability to control other tribes, and became the nominal co-lord of the Tatars, but in fact, the Tatars were divided into three parts, and the Chahar could control only the three tribes belonging to the left wing.

It is precisely because of this that the Ming Dynasty has not had a large-scale war with the Tatars since the Tumubao Change, and the Tatars are eyeing the Ming Dynasty on a large scale.

But now, now that the Chahar Department and the Turmer Department have reached an agreement, Zhu Changluo naturally has to make countermeasures, there is a saying in later generations, called the enemy's enemy is a friend, the Horqin Department will not say it for the time being, the Oirat's Department and the Chahar Department are mortal enemies, as long as they can contact the Oirat's Department, when the time comes, even if the Chahar Department and the Tulmer Department join forces, they may not be able to bear it!
