We must first know that the Anshi Rebellion was launched by An Lushan and Shi Siming in the last year of Tang Xuanzong in the last year of Tang Xuanzong (755-763), therefore, this incident is also called Anshi Rebellion, although it was finally pacified, but after seven years of war, it had a serious impact on the politics, economy, society and culture of China's descendants, and the Anshi Rebellion was also an important event in Chinese history, and this war led to the Tang Dynasty from prosperity to decline, and the Tang Dynasty has never returned.
We are talking about the cause of the Anshi Rebellion, mainly the contradiction between the ruling class and the people, although, in the Tang Dynasty Xuanzong Kaiyuan years, the social economy was unprecedentedly developed, and there was a prosperous situation, but at this time, the land annexation was serious, resulting in the destruction of the Juntian system, and the Juntian system was a system of distributing land according to population from the Northern Wei Dynasty to the early Tang Dynasty, and the corruption of the ruling class in the Tang Dynasty led to the people's burden and important people's entry into the water and fire, coupled with the contradictions within the ruling class, the contradictions between the nationalities, ** Conflicts between localities eventually led to the outbreak of the Anshi Rebellion.
Let's talk about Tang Suzong's order in 758 that Guo Ziyi, Li Guangbi and other generals led an army of 200,000 to attack An Qingxu, the offensive of the Tang army was still very fierce, captured Weizhou, forced An Qingxu to retreat to Yecheng, all this smoothly foresaw that the Tang army may soon defeat An Qingxu, in Guo Ziyi ordered the siege of the city and water irrigation Yecheng, resulting in its successive losses and generals, unable to fight again, no choice but to hold on to Yecheng, no choice but to send people to find Shi Siming to rescue, although, Shi Siming led the army to defeat the Tang army, but its aid did not save, waiting for the opportunity.
Let's talk about the army sent by the Tang Army in this battle, a total of 200,000 people, it can be said that although the momentum is huge, but, mixed with fish and dragons, it can be said that such an army does not have a good commander, it will definitely have an impact on the later battles, this battle is led by Guo Ziyi and Li Guangbi two generals, there is no real marshal, and the eunuch Yu Chaoen came to serve as the supervisor of the army, which led to the major festivals to make no one obey anyone, laying a hidden danger for the subsequent war.
Although, he captured Weizhou in December, but waited until February of the following year, and this led to the Tang army after a few months of siege, the army was tired and demoralized, and Shi Siming has been waiting for an opportunity, at this time he sent troops, and the victory rate would be greatly increased, so he chose to send troops.
Serious infighting, led to the Tang army no one obeyed anyone, although, when the Tang army first started the war, the two sides were about the same, but, later, when Guo Ziyi and Shi Siming were at war, the internal contradictions of the Tang army broke out, and the quarrel between the generals of Han and Hu led to the instability of the army.
After this battle, the eunuch Yu Chaoen framed Guo Ziyi for all the blame for the fiasco, causing Guo Ziyi to take away the military power, which was not activated again until the Tibetan invasion.
