Emperor Dezong of Tang was the ninth emperor of the Tang Dynasty and the son of Emperor Tang. When he was the crown prince, he served as the marshal of the Terracotta Army, so nominally the unified army quelled the Anshi Rebellion.
The Anshi Rebellion broke out during the reign of Emperor Xuanzong of Tang, and the rebellious An Lushan was the emissary of the three towns of Fanyang, Pinglu, and Hedong. The rebellion lasted for nearly eight years, when Li Shi was the crown prince, and he was deeply touched by the rebellion and deeply worried about the decline of the Tang Dynasty from its peak to the decline.
Therefore, after Tang Dezong ascended the throne, he began a series of reforms, and the Tang Dynasty at that time had a positive atmosphere. At the same time, he also began to cut the domain.
In the second year of Tang Dezong's succession, ChengdeZhen Jiedu in Hebei caused Li Baochen to fall ill and die. As was customary, power would be taken over by his own son after his death. Therefore, his son Li Weiyue petitioned to inherit his father's throne.
At this time, Tang Dezong was just about to cut the domain, and he thought that the domain could not continue to be like the emperor in such a father and son, so he refused. As a result, Li Weiyue was not a fuel-saving lamp, and he united several knots to make a rebellion.
However, in the process of cutting the domain, Li Shi used the town to fight the town, which greatly displeased the jiedushi who participated in the battle of the imperial court, resulting in a reversal of the situation. The war spread from Hebei to Henan at once, and the eastern capital was in a hurry.
At that time, when Tang Dezong was preparing to transfer to the Jingyuan soldiers and horses on the Huaixi front to suppress the rebellion, passing through Chang'an, because they did not receive the coveted reward, and the meals served were brown rice and vegetarian dishes, the soldiers mutinied, which is the famous "Jingshi Change" in history.
At this moment, Tang Dezong was forced to flee Chang'an. Li Shi also painfully issued a "crime against himself", declared that "the truth is not a monarch", and openly assumed the responsibility for causing chaos in the world.
After this incident, Tang Dezong no longer cut the domain, but began to condone the domain, and at the same time began to reuse eunuchs.
Then, why did Tang Dezong's desire to cut the domain end in failure?
Objectively speaking, Tang Dezong's slashing of the domain was a bit of a rush to make a quick profit. At that time, he had just succeeded to the throne for a year, many things were not on track, they were not familiar with it, and it was already very good to be able to get to know the courtiers, but in the second year, he began to cut the domain in a hurry.
It should be known that not long after the Tang Anshi rebellion was settled, many clan towns were still contributing at that time, and at this time, cutting the clan gave people the feeling of unloading and killing donkeys.
Moreover, at that time, the only thing that the imperial court could rely on was the Divine Strategy Army, so Tang Dezong adopted the strategy of using the fan town to fight the town, but despite this, it eventually caused the Tang Dynasty to fall into a situation of war on all sides, and a little carelessness was likely to reverse the situation, and sure enough, the Jingyuan soldiers and horses who were going to the front line to suppress the rebels suddenly mutinied, causing Tang Dezong to flee.
For a time, the imperial court completely lost the initiative. Of course, if he had the determination, in fact, it could be exactly the same as the Anshi Rebellion in that year, but unfortunately he did not, and even when he fled, he saw that the eunuch was very loyal, so he gave the command of the forbidden army to the eunuch.
After all, the imperial court was short of troops and finances at that time, coupled with great shortcomings in strategy and preparation. As a result, this passively triggered force slashed the domain and ended in failure.
