The most powerful stage of the Tang Dynasty is nothing more than two stages, one is the rule of Zhenguan led by Li Shimin of Tang Taizong, and the other is the prosperity of Kaiyuan led by Li Longji of Tang Xuanzong.
The Tang Dynasty in this period was the first center in the world, and Chang 'an in this period was the largest metropolis in the world. As for the strength of the army in the Tang Dynasty, the attitude of ethnic minorities at that time was the best embodiment of the national strength of the Tang Dynasty. At that time, ethnic minorities were uncharacteristically, because most of the ethnic minorities in history were aggressive to the Han nationality. Once they were strong, they would invade the Han nationality. Generally speaking, ethnic minorities rarely merged with the Han nationality. Only when the Han nationality was particularly strong, ethnic minorities changed from being brave and brave to being good at singing and dancing.
At that time, ethnic minorities, such as Turks and Mongolians, changed from being brave and good at fighting to being good at singing and dancing. In the early Tang Dynasty, there were many generals who expanded to the outside world, from Weichi Gong in the founding period to Wang Zong in the later period, all of them were rare generals.
Li Shimin himself is a general who can recruit good fighters. He shot down all the mountains and rivers of the Tang Dynasty. In the early stage, when he fought with his father Li Yuan, he was basically leading the battle. He was directing the battle, so Mao Zedong had that poem. In the past, Qin Huang Hanwu, Tang Zong Song Zu, that is to say, a great man like Chairman Mao, for the emperors of China's ancient feudal dynasty, only appreciated these four Han emperors, while the other three emperors basically had different degrees of military command ability. But to say that these four emperors, it was Li Shimin who really had command ability. After all, he laid more than half of the mountains and rivers in the Tang Dynasty. His father Li Yuan, as an emperor, actually allowed his son Li Shimin to establish himself.
