At that time, there was a cavalry in the Tang Dynasty who was not inferior to nomadic people and could launch a surprise attack in the Gobi Desert. Therefore, the foreign war in the early Tang Dynasty achieved good results. This is also an important reason why the Great Wall was not built in the Tang Dynasty.
But as time went on, things changed.
In the later period of Xuanzong in Tang Dynasty, Li held the political office for 19 years. Yang Guifei's younger brother Yang and An Lushan fought for power and profit, which became the fuse of Anshi Rebellion. In addition, there are also differences between Ge, the envoy of the Northwest School, and An Lushan, the envoy of the Northeast School.
Moreover, due to the destruction of the land equalization system and the government soldier system in the Tang Dynasty, the government soldier system had to be replaced by the recruitment system since Xuanzong of the Tang Dynasty. These recruited professional soldiers have been bought by our times, forming a complicated relationship.
After Kaiyuan, the system of our time was generally established in the frontier defense, and their power was growing. As for it? It has its land, people, soldiers and wealth. Form a situation where the tail is too big to fall.
There are 490,000 border guards, accounting for more than 85% of the country's total strength, mainly concentrated in the northeast and northwest borders, and only three towns, such as john young, director of An Lushan, have150,000 people. The Central Army is not only insufficient in quantity, but also poor in quality. It is usually unprepared for war and vulnerable to war.
Our times are getting stronger and stronger, and the contradiction with the central authorities is getting deeper and deeper. In the last years of Tianbao, the Anshi Rebellion finally broke out.
Was it incorporated into the Eight Banners in the Qing Dynasty? Flag bearer? People who are not in the flag are treated differently. At the beginning of entering the customs, the Qing court adopted a large scale? Enclosure? Activities, a large number of fertile land occupied by the people are classified as flags; Exempt the flag bearer from taxes and labor. Preferential policies have led to the decadence and parasitism of flag-bearers, which has led to the abandonment or even appearance of their descendants? Livelihood? question
After the rise of local powerful warlords such as Xiang Army, all possibilities became impossible. In addition, the late Qing Dynasty was an unprecedented change in China for thousands of years, and the level and virtue of the children of the Eight Banners were clear to both the emperor and foreigners. Whenever the flag army is useful, Zhang Zhidong and Zeng Guofan have no accidents.
