Duoyan Sanwei is also called Wuliangha Sanwei, namely: Duoyan Sanwei, Taining Sanwei and Fuyuwei, which is what they were called in the Ming Dynasty. Duoyan Sanwei was formerly a Mongolian tribe living in the east and near Daxing 'anling in Inner Mongolia. These tribes mainly include Wuliangha, Wengniute, Wuqiyete and Zhala Yier.

1. Wuliangha Department

Wuliangha Department is mainly descended from Genghis Khan's youngest brother, Tiemu Gewo Chijin, and his nephew, Eldai, who were sealed to the east of Daxing 'anling by Genghis Khan, and their activities include the whole of Heilongjiang Province, Jilin Province and the northeast of Inner Mongolia today.

In addition, there are descendants of Genghis Khan's famous soldier Lerou, who also live in this area and are called the Wuliangha Department.

Second, Weng Niu Te Bu

Weng Niu Te Bu is said to be a descendant of the Donghu tribe in the Warring States Period. It used to live in the northern part of Zhao, but later it split into Xianbei and Wuhuan, and some Wuhuan people moved eastward to the Nenjiang River basin. This part of Wuhuan people is the ancestor of Mongolian Weng Niu Te Bu, and this Mongolian tribe is mainly a descendant of Genghis Khan's third brother Nuochuin.

The descendants of Nuochuin have a man named Bayan Daiqing Hongguo 'er Nuoyan, and his tribe is the Onniute tribe, who mainly lives in Hulunbeier, Inner Mongolia.

In addition, Genghis Khan had a younger brother named Biele Gutai, and some descendants of Biele Gutai were stationed in the east of Daxing 'anling, also known as Wengniutebu. Even today, there are Wengniuteqi in Inner Mongolia.

3. Uqi Yete Department

Uqi Yete Department is a descendant of Genghis Khan's second brother, Humble Red Gesar, whose fief was in Hulun Lake and Hailaer River in Inner Mongolia today, and later included Nenjiang Plain and Horqin Grassland.

Fourth, Zhala Yier Department

Zhala Yier Department is one of the tribes of Dieliejin Mongolia, which means ordinary Mongols in Mongolian, and Wuliangha Department is also one of the tribes of Dieliejin. It lives in Zhala Yier Department in Daxinganling, and is mainly a descendant of Muqali, a famous soldier under Genghis Khan.

At the end of the Yuan Dynasty, Zhu Yuanzhang gradually unified the world and began the Northern Expedition. In 1388, the general of the Ming Dynasty, Lan Yu, defeated the Mongolian Khan Tuogutimur in the battle of fishing children's sea, wiped out the Mongols in this area, and opened the door to enter the Daxinganling Mountains and the Mongolian tribes farther north. At that time, the Mongolian tribes located in the east and near Daxinganling lost their barriers. In desperation, these Mongolian tribes surrendered to Zhu Yuanzhang.

Zhu Yuanzhang organized these Mongolian tribes who took refuge in the Ming Dynasty, such as Wuliangha, Wengniute, Wuqiyete, Zhala Yier, into three guards according to the establishment of the Ming Dynasty, that is, Duoyanwei, Tainingwei and Fuyuwei, referred to as Duoyansanwei or Wuliangha Sanwei for short. The guards of the Ming Dynasty are equivalent to today's military regions or war zones.

The standard of dividing into three guards is divided by region, but Mongolian tribes don't necessarily live by region, and there are mixed living phenomena, so many Mongolian tribes are disrupted and divided into three guards according to their places of residence.

1. Duo Yanwei

Duo Yanwei's defense zone is in the upper reaches of Quxier River (now a tributary of Taoer River belongs to Leli River) and in the area of Duoyanshan, and Tuolu Huchar is under the command of Duo Yanwei.

2. Tainingwei

Tainingwei's defense area is in the Taer River (now Taoer River) basin, with Azashiri as the commander of Tainingwei and Tabin Timur as the commander.

3. Fu Yuwei

Fu Yuwei's defense area is in the Nenjiang River and Fuyu River (now Wuyuer River), and Haisa Nan replied that Xi was the commander of Fu Yuwei.

Duoyan Sanwei * * * has more than 8, Mongolian cavalry. During the period of Zhu Yuanzhang, Duoyan Sanwei was under the jurisdiction of Ning Wang Zhu Quan, and Zhu Quan's fief was in Duolun, Inner Mongolia at that time. At that time, it was called Daning, and Xifeng Pass was also here. Zhu Quan's main role was to guard the border and prevent Mongols from invading, so his Duoyan Sanwei was an elite division.

In p>1399, Zhu Yunwen, Emperor Jianwen, ascended the throne. In the same year, he began to cut the vassal, and the Battle of Jing Nan broke out. At that time, Zhu Di was a prince of Yan, and his fief was in Beijing. In order to avoid being cut the vassal, Zhu Di rose up against Zhu Yunwen. At first, Zhu Di was weak. In order to enhance his strength, Zhu Di thought of Duo Yan Sanwei under Zhu Quan, the king of Ning. This was 8, elite.

So Zhu Di found Zhu Quan and went into the city alone to talk with Zhu Quan, but secretly deployed troops to capture Zhu Quan, the king of Ning, who was seeing him off, and forced Zhu Quan to join him. Zhu Quan had no choice but to join Zhu Di. In the three-year battle of Jing Nan, Zhu Di defeated Zhu Yunwen and invaded Nanjing, and Zhu Yunwen disappeared. Later, Zhu Di became emperor, that is, Ming Chengzu.

Probably during the Battle of Jing Nan, Duo Yan Sanwei betrayed the Ming Dynasty. For the whole Mongolian tribe, Duo Yan Sanwei is not big, because there are still a large number of Mongolian tribes living in the west of Daxing 'anling and the whole Mongolian Plateau, including the Great Khan of Beiyuan, and Duo Yan Sanwei later took refuge in the Great Khan of Beiyuan.

during the period of Zhu Yuanzhang, the Ming army made many large-scale northern expeditions, which caused heavy losses in the Northern Yuan Dynasty, and further retreated northward to avoid the sharp edge of the Ming army. By the time of Zhu Di, the Mongolian tribes in the north began to stir again. In order to stabilize the north, Zhu Di, the Ming emperor, made five northern expeditions.

The main purpose of Zhu Di's Northern Expedition was to crack down on Mongolian Tatars and Wala. After the defeat of the Northern Yuan Dynasty, Mongolia began to fall apart. There were two major regimes, one was Tatar, and the other was Wala. Tatar and Wala also fought against each other.

Tatar is near the Ming Dynasty, and Wala is far away from it. Zhu Di defeated Tatar in the first northern expedition, and his grandmaster Arutai surrendered to the Ming Dynasty. As soon as Tatar was defeated, Wala became strong again. Wala defeated Tatar first, then invaded the Ming Dynasty, and Zhu Di made a second northern expedition, which directly reached this day.

After Zhu Di defeated Wala, the Tatar Department rebelled again, so Zhu Di made the third, fourth and fifth northern expeditions. In his later years, Zhu Di was either in the northern expedition or on the way to it. At that time, the Mongolian ministries rebelled against the Ming Dynasty. When Zhu Di came, the Mongols either surrendered or fled, and Zhu Di finished the Tatar.

during the third northern expedition to Arutai, the Tatar's Grand Priest, Zhu Di also conquered Duo Yan Sanwei, who did not obey the Ming Dynasty. Naturally, Duo Yan Sanwei was no match for the Ming Dynasty and surrendered to it again. In fact, Duo Yan Sanwei was also rebellious to the Ming Dynasty. Because he was far away from the Ming Dynasty, he was of the same clan as Tatar and Wala, so he rebelled from time to time, which led to the discussion of Zhu Di's army.

In fact, there is another reason that caused Duo Yan Sanwei's rebellion from time to time, that is, the Ming Dynasty's policy towards Mongolian tribes. Looking at Zhu Di's several northern expeditions, it did not achieve much success. Tatar and Wala always existed. The Ming Dynasty's policy was simple military crusade+courting. This policy did not make the Mongols completely submit, but caused several northern expeditions, wasting people and money.

The best way is close assimilation and divide-and-conquer. Mongolia can't be destroyed, but it can only be wooed and ruled by * * *. There are many Mongolian tribes, which are widely distributed, and there are also many contradictions within them. We can use the internal contradictions of Mongolia to pull one and fight another, and move the Mongolian tribes that surrendered to ourselves to the residence of the Han Dynasty, so that the Han culture can assimilate Mongolia. In a few years, Mongolia will be sinicized, just by Zhu Di's military attack.
