How the Tang Dynasty founded and unified China

The founder of the Tang Dynasty was Li Yuan, a general of the Sui Dynasty and a defender of Taiyuan. In 618, Li Yuan secretly established the Tang Dynasty amid the sound of peasant uprisings and wars in the last years of the Sui Dynasty. Taking advantage of the unpreparedness and seizing Chang'an, he made full use of the situation of the Sui Dynasty and the peasant rebel army to quickly establish the Tang Dynasty.

From the establishment of the Tang Dynasty to the reign of Li Yuan's son Li Shimin, from 618 to 628, he destroyed the forces of the separatist parties and completed the unification, which lasted ten years.

Not only unified, but also open up the territory to expand the territory, the Tang Dynasty heyday of the territory area of about 16 million square kilometers, the northwest of the territory to the Aral Sea, directly bordering today's Iran, called Longyou Road, set up the West Capital Protectorate and the East Capital Protectorate; To the north, it reaches Lake Baikal, which is the Chita region of today's Russia, called Kannai-do; The southern part includes all of Vietnam and is called Lingnan Province; To the northeast, as far as the Zhugzhur Mountains of present-day Russia (including Sakhalin Island), it is called Hebei Province. <>

Map of the territory of the Tang Dynasty.

By the standards of the Qin Dynasty, the Tang Dynasty was unified, and its rule in the southwest was much the same as that of the Qin Dynasty, with a portion of the Korean Peninsula in the northeast (Liaodong) than the Qin Dynasty, the Hexi Corridor in the northwest, and Beiyue in the south (which was then under the jurisdiction of Lingnan West Province, which was later Guangxi). According to the system of the Han Dynasty and the Ming Dynasty, the Tang Dynasty was missing Yunnan. According to the Yuan and Qing dynasties, they will say that the Tang Dynasty opened up the territory on the map, and never actually controlled it in the northeast, and there was a lack of the Tibetan region, and they would expel Liaoning from the Han land.

If we follow the tradition of ancient history, it must be a great unification, and if we follow the current territory, then the Qinghai-Tibet Plateau will not be counted, and it will not be completely unified.

The Tang Dynasty Unification War was a war of unification against the separatist regimes established in various parts of China in the last years of the Sui Dynasty after the establishment of the Tang Dynasty.

From the first year of Wude to the second year of Wude (618-619), Li Shimin led the Tang army to defeat Xue Ju and Xue Rengao father and son in Jincheng. He also captured Li Liang by intriguing, and he had all the land west of the river without swords. [1-2] In the third year of Wude (620), Li Shimin led the army and civilians to counterattack, eliminated Liu Wuzhou, and restored his rule over Daibei.

After three military and political activities, the Tang Dynasty not only consolidated the base area in Guanzhong, but also expanded its territory and developed its power, so that it could concentrate its forces on managing the Central Plains and Jiangnan and achieve the goal of reunification. [1] In the same year, the Wagang Army had collapsed, most of the counties in Shandong had fallen to the Tang Dynasty, defeated Wang Shichong and Dou Jiande in the Central Plains, and later suppressed Liu Heimin, Xu Yuanlang, and Gao Kaidao, and the Tang Dynasty established its rule in Henan, Hebei, and Shandong. [1] [3] In the fourth year of Wude, Lingnan in the Lianghu region was incorporated into the territory of the Tang Dynasty, and in the seventh year of Wude, Du Fuwei's general Fu Gongyi was destroyed, and Jiangnan was pacified.

1] [4-5] By the 7th year of Wude (624), the Tang dynasty had established its own rule throughout the country, with the exception of the Liang Emperor Liang Shidu of Shuofang. Liang Shidu relied on the protection of the Turkic nobles to be able to divide Shuofang. In the second year of Zhenguan (628), Tang Taizong took advantage of the Turkic decline and sent troops to destroy Liang Shidu.

In the end, the Tang Dynasty was able to sweep away the heroes and reunify the world. Li Shimin played a huge role in this unification war, and after ascending the throne, he created the "rule of Zhenguan", which created the prosperity of the Tang Dynasty.

The Tang Dynasty relied on the power of the gate lords, and Li Shimin led the troops to conquer and unify the whole country.

The Tang Dynasty unified the whole country, and after defeating the Sui Dynasty army, as well as various rebel armies represented by Wang Shichong and Dou Jiande, finally unified the country.

No matter which dynasty is unified? They all need to be encouraged, how can there be so many and friends to evolve without.

If you marry with the major families, you don't see it, even the leaders of the ethnic minorities in the border areas can marry a princess as long as they pay tribute.

It's relatively simple. The regime established by Li Yuan, and later under the rule of Li Shimin, the Tang Dynasty became more and more powerful.

In history, the process of establishing the unification of the Tang Dynasty was mainly due to Li Yuanyuan's army in Taiyuan and the elimination of the Sui Dynasty army, as well as various anti-kings and the establishment of the Tang Dynasty.

It is to support a Yang Sui puppet emperor first, and then gradually pacify other forces, and after defeating them, it is enough.

Through continuous conquest to subdue other forces, a process in which big fish eat small fish.

In November 617 AD, Li Yuan, the Duke of Tang Dynasty, Li Shimin broke through the army of Qu Tutong, invaded Daxing in Sui Jing (the Tang Dynasty was still in the capital in the future), supported Yang Yu as the emperor, was Emperor Gong of Sui, changed Yuan Yining, and respected Emperor Yang as the Emperor Taishang, appointed himself as the prime minister, and entered the Tang Dynasty.

In May 618, Li Yuan forced Emperor Gong of Sui to take the throne and proclaimed himself emperor, with the country name Tang as Tang Gaozu. Changed to Yuan Wude, the capital was still set in Daxing, and the name was changed to Chang'an. After Li Yuan established the Tang Dynasty, he used Guanzhong as a base to gradually unify China.

In 618, Li Shimin pacified Xue Ju and Xue Rengao in the northwest, and in the same year, Luo Yi surrendered to the Tang Dynasty in Youzhou, and in the same year, Li Fazhu surrendered to the Tang Dynasty because of the defeat with Wang Shichong in the Yuyi competition, which made the military strength of the Tang Dynasty grow rapidly, so that in the future, the princes in the Central Plains were leveled, and the tiger was based on the Central Plains, which was the foundation for the unification of the world.

In 620, he sent Li Shimin to defeat Liu Wuzhou and Song Jingang, who had invaded Hedong (present-day southwestern Shanxi), and then Emperor Shichong of Luoyang and Dou Jiande, King of Xia of Hebei, joined forces to resist the Tang Dynasty.

Xiao Miao, who seized Jiangling, was pacified by Li Jing and Li Xiaogong in 621. The following year, Lingnan Feng Ang surrendered, and Qianzhou Lin Shihong died. The Tang Dynasty basically unified the Han land.

In 622, Li Shimin defeated the coalition army, captured Dou Jiande, and Wang Shichong surrendered. The rest of Dou Jiande's Liu Heimin was also defeated by Li Jiancheng, and Hebei was pacified.

In 623, Fu Gongqi led the rest of Du Fuwei's troops to oppose the Tang in Danyang (present-day Nanjing, Jiangsu), and was captured and killed by the Tang army the following year.

In 618 AD, Li Yuan proclaimed the emperor in Taiyuan and built the capital Chang'an.
