After the death of Tang Wuzong, the eunuch chose Li Chen to inherit the throne and wanted to continue to maintain the government. After www.biquge.info his accession to the throne, he made great efforts to govern the country, degraded Li Deyu internally, ended the Niu Li party dispute, restrained the excessive expansion of the eunuchs' power, and cracked down on the lawless magnates and relatives.

During his reign, Xuanzong governed the country diligently and thriftily, sympathized with the people, reduced taxes, paid attention to the selection of talents, changed the policy of blocking Buddhism of Tang Wuzong, and respected Buddhism again. The purging of Hexi made the Tang court have no worries about the west, the Tang Dynasty's national situation improved, and the people became richer day by day, so that the already very decaying government showed a well-off situation. In fact, the state was not stable, and in the later years of Tang Xuanzong, there was chaos in the country, and a rebellion broke out soon after his death.

During the reign of Emperor Taizong of the Tang Dynasty, the world was divided into ten provinces according to the situation of mountains and rivers and convenient transportation, and supervisory officials were set up to assist the central government in supervising the state-level administrative regions according to the needs.

The Juntian system of the Sui Dynasty gradually declined in the normal development, the domestic land annexation, the Tang Empire's outward expansion mechanism was blocked, from attack to defense, the government military system in the early Sui and Tang dynasties degenerated into a conscription system, Tang Ruizong Jingyun period, began the Jiedu envoy system, and set up a full-powered military and political chief in the border local military towns.

On the basis of his father, Xuanzong set up the famous Tianbao Ten Sections, plus the highest level of the Dao, under the Dao there are large and small sections of military towns, large and small sections of the degree of jurisdiction over several states, small defense envoys, regimental training to govern individual states. The real state and county two-level local administrative structure was lax, and began to evolve into a virtual three-level local administration, and finally the local power was concentrated in the military towns of Jiedu, and the feudal towns and towns were able to break through the control tradition of the imperial court taking turns to change territories, not concurrently speaking, and not serving in their hometowns. Completely get rid of the control of the central court, the good ones listen to the tunes and do not listen to the announcements, the financial income, the right to appoint and dismiss personnel, and even the hereditary rule, break free from the shackles in one go, and the bad ones directly rebel against the court and become actually independent.

The Tang Dynasty made great efforts in the early Tang Dynasty, and the expansion of the territory of the Tang Dynasty was at its peak, until it was saturated and contracted, and the military town was able to penetrate the system from the periphery to the interior and popularize it, and the territory of internal and external troubles was reduced, until the peasant uprising, the Tang Dynasty was replaced by the big feudal towns, and the large and small feudal towns evolved into a great division of five dynasties and ten kingdoms. During this period, more than 40 feudal towns fought each other and attacked each other, uniting against the Tang Dynasty.

The feudal towns rose and fell, their positions were uncertain, they fought in successive battles, and poisoned the world. Like raising Gu, dozens of poisonous insects fight back and forth in the host's body, occasionally settling for the host's use, dog-eat-dog, and it is stable for a while. In the end, it intensified, the poisonous insects swallowed each other and attacked, dozens of poisonous insects raised more than a dozen, the largest one bit the host to death, and it could not be replaced for a while, and then strangled each other with other big poisonous insects.

It was too terrible, too dark, too complicated, and the local real power was too great to be able to cause disaster to this point, from the Pandora's box of the Anshi Rebellion of Xuanzong of the Tang Dynasty to the opening of the Pandora's box to the overall reform of the administrative and military economic system of the Song Taizu's cup of wine, and the complete reform of the administrative and military economic system of the right culture and military suppression.

The feudal town was a disaster, the soldiers mutinied, the generals rebelled, rebelled against the imperial court, and the feudal marshal killed his subordinates. The lowest-ranking soldier kills the general, and the commander of the general kills the commander of the feudal town, and the commander of the feudal town rebels against the imperial court. Due to the constraints of power among the feudal towns, the martial style and arrogant characteristics of the Tang Dynasty army, as well as the military system organized by the tooth soldiers, and the reasons for the financial autonomy of the feudal towns and the localization of military expenditures, the decentralization of power at all levels, the centralization of power retrograde, and the chaos of the system.

Why was An Lushan able to shake the prosperous Tang Dynasty and knock it down to the altar in one fell swoop, with such a big contrast? Because he was favored by Xuanzong and concurrently served as the envoy of the three major festivals, Fanyang, Pinglu, and Hedong, and An Lushan held Hebei, Shandong, and Shanxi, which was simply overwhelming, and changed the entire thousand-year-old national fortune of Tang Dynasty and China.

Suzong and Daizong quelled the rebellion, Xuanzong fled to Shu for refuge, Suzong set up another imperial court in Ningxia, northern Shaanxi, and all the military towns were enlarged to assist in quelling the rebellion.

Guo Ziyi and Li Guangbi, the two great fathers of the restoration of the country, were born from the bottom of the army of the feudal town, and the Tang Dynasty used the feudal town to level the feudal town. In the end, the balance of power was reached, and the leaders of the Hebei rebels in the Anshi Rebellion were destroyed, leaving the bottom army, and the actual control of the feudal town was still not recovered. And because the counterinsurgency expanded the number and power of the feudal towns, the imperial court pro-feudal towns confronted the rebellious independent feudal towns.

At this time, the Tang court broke out in external troubles, and the Turks, Hui, and Tibetans were suffering from internal and external difficulties, and in order to solve the internal and external new contradictions, they did not eradicate and recover the actual control of the rebellious feudal towns in time. On the contrary, it supports the pro-feudal clans that quell the rebellion, and establishes the relationship between the opposing feudal towns to play a balanced seesaw.

After Xuanzong, Suzong and Daizong were in the period of quelling the turmoil, Dezong was the period of expansion of the feudal town, Shunzong transitioned, Xianzong was in the middle of the period, Muzong regained its strength and rebelled, and when Xuanzong was evenly divided, during this period, the eunuchs within the court set up the monarchy, Mu Zong and the eunuchs killed his father Xianzong, and the eunuchs purified the civil officials and courtiers during the Wenzong period, and the internal power structure of the Tang court was loose and the centralization was retrograde. Until the last years of Yizong, it continued to maintain a semi-independent state, and the rebellion of Huangchao of Yizong took the opportunity to expand violently, melee with each other, and annexed and destroyed the Tang Dynasty.

Dezong was self-defeating, the feudal domain could not be reduced, it was difficult to Fengtian, the prestige of the Tang court fell sharply, and the power of the feudal town was extremely strong. After the Anshi Rebellion, a series of feudal towns were divided from north to south, and Tang Dezong was ambitious to cut the feudal domain.

The Jiangnan Caifu Domain supported the national imperial court's finances, formally reformed the collapsed Juntian system, and used the two tax laws to use the Gyeonggi Directly Affiliated Domain and the Forbidden Army to unite the Central Plains Domains to attack the four major thorns of Hebei and Shandong, and provoked the rest of the feudal towns to fight each other. All kinds of means were exhausted, Huairou suppressed and sowed discord, but he still failed.

The three towns of Hebei, also known as the three towns of Heshuo, Fanyang, Chengde, and Weibo, were the source of the rebellion. Hebei is an important place for raising horses and military resources, and in the Anshi Rebellion, An Lushan, Shi Siming, father and son, have been entrenched in the nest for many years.

At the end of the counterinsurgency, Shi Chaoyi's troops surrendered Zhang Zhongzhi, Tian Chengsi, Li Huaixian, and Xue Song to the official army, Shi Chaoyi committed suicide, and the Tang Dynasty was unable to completely eliminate the remaining party.

Lulong Town, the base camp of Anshi, the head of the three towns. Li Huaixian, who was later killed by the general Zhu Xicai, ruled in place of the Zhu family, he was the envoy of the Lulong Festival in Youzhou, and commanded Youzhou, Ying, Ping, Ji, Fei, Tan, Mo Qizhou, stationed in Youzhou.

Chengde Town, Zhang Zhongzhi was the envoy of the Chengde Army, given the name Li Baochen, Tongheng, Zhao, Shen, Ding, Yi five states, and soon increased Jizhou, stationed in Hengzhou.

In Wei Bo Town, Tian Chengsi was the defense envoy of Wei, Bo, De, Cang, and Ying.

Xue Song was the envoy of the Xiangwei Festival, and later moved to the Lujie Envoy, ruling the southwest of Hebei and Shanxi, Henan each one, originally Hebei had a total of four towns, and then the Xiangwei was annexed by Tian Chenghei and became three towns. The three towns of Heshuo and the Tang court of Dezong, who were determined to cut the feudal domain, repeatedly tug-of-war, and spent countless financial and military expenditures.

There is also An Lushan's concurrently served as the territory of the Pinglu Jiedu envoy, after the rebellion was recovered, the Tang Dynasty was helpless and could not be controlled, and the rebel general Wang Xuanzhi was guarded by the Jiedu envoy, and the rebel general Hou Xiyi, who returned to Shun after his death, stood on his own initiative. He was expelled by Li Huaiyu, a general, and became a handsome man, and Li Huaiyu was given a proper name. and Tian Chengsi, Xue Song, Li Baochen, Liang Chongyi and other parties.

Pinglu Town, Li Zhengji, Li Lingyao rebelled after the Biansong Dynasty, this is one that Dezong successfully extinguished, but after the extinguishment, the fruits of victory were picked by the feudal town, and took the opportunity to occupy Cao, Pu, Xu, Yanzhou, Yunzhou, and the original Ziqing and other ten states, a total of fifteen states, the strongest and largest feudal town, hereditary three generations and four people.

In Xiangyang Town, Liang Chongyi was the envoy of Shannan Dongdao, who ruled the northwest of present-day Hubei for 19 years and was extinguished.

In Huaixi Town, Li Xilie was the envoy of Huaixi Jiedu, governed Caizhou, directly rebelled, proclaimed himself the king of Jianxing, and united the four towns of Ziqing, Weibo, Chengde, and Lulong, who had been called kings, to resist the Tang Dynasty. Dezong mobilized the Taoist soldiers from Huaixi to attack Li Xilie, and all the Taoist soldiers waited and watched.

Yi Hee-yeol's rebellion was a turning point in Dejong's cause to reduce the feudal domain, and the mobilization of the combined forces of the pro-feudal and the directly subordinate feudal towns failed to attack, and the actual secession of the feudal towns could not be moved. As a last resort, the troops of Jingyuan, a border guard army directly under the defense of Gyeonggi, went east to the rescue, and when the army passed through the Beijing Division, there was a rebellion, and Zhu Zhu was the emperor of Qin, and Dezong went to Fengtian. The earth-shattering changes almost bloomed in the middle, the black tiger was heartbroken, and Tang Tingsheji's death was thrilling.

Zhu Zhu's younger brother Zhu Tao succeeded Zhu Zhu into Beijing to accept Huairou appeasement, took over as Lu Longjie's envoy, and Zhu Zhu in Chang'an should cooperate with the outside, trying to subvert the Tang Dynasty, Dezong fled to Fengtian was besieged, called Fengtian difficulty, the general Li Huaiguang rescued and relieved the siege, was instigated by the courtier Lu Qi and others, did not let him enter the court, so instead united with Zhu Zhu to rebel, Dezong then fled to Liangzhou. The famous general Li Sheng cleaned up the mess and countered the rebellion and recovered Chang'an.

After the great crisis, Zhu Zhu was killed by the generals, Li Huaiguang was killed by the generals, Li Xilie was poisoned by the general Chen Xianqi, and Chen Xianqi was killed by Wu Shaocheng instead, and Huaixi Town was temporarily stable. The four towns of Hebei and Shandong also expressed their renewed obedience to the imperial court, and the situation in the whole country was ostensibly reunited and stable.

After the Jingyuan Mutiny, Dezong stopped cutting the feudal domains and switched to implementing a policy of appeasement, increasing the use of eunuchs. However, he still did not forget the matter of cutting the feudal domain, strengthened the forbidden army, enriched the treasury, and accumulated strength to prepare for the future.

Xianzong's talent, the monarch and the minister got along, the strange people came out for a while, the Tang court succeeded in cutting the domain, the central monarchy was restored, the court suppressed the localities, and there was a great trend of reviving the glory of the unified empire. The trend of centralization rebounded, Yuan and Zhongxing, but unfortunately in the end, Xianzong committed the old mistakes of the ancestors Taizong and Xuanzong, and his achievements were at their peak, and he immediately swelled, and he died and died.

Xianzong is the grandson of Dezong, Xianzong's father Shunzong was the prince at that time, Dezong is old and likes this grandson Xianzong very much, when he was a child, he held him on his lap to play, felt that he looked like Taizong, teased the child and said who are you? Xianzong said domineeringly: "The third son!"

When Dezong died, Shunzong's stroke power quickly transitioned into the hands of Emperor Sun Xianzong, and Shunzong's power was abdicated by Xianzong soon after he ascended the throne. The difference is that Kenjong did it.

In the short 200 days of Shunzong's reign, he appointed Wang Shuwen and Wang Ling, who were close associates when he was the crown prince, to lead the reform of centralized power, both internal and external, and to fight against the eunuchs of the feudal towns, but failed. Because of Shunzong's stroke, the head of the Erwang literati group, and the direct relatives Bashu Weigao and Liu Pi were also suppressed because they wanted to break away from the control of the imperial court, and took refuge in the crown prince Xianzong, and Xianzong took advantage of the eunuchs who were also suppressed to get closer to him, and forced Shunzong to take the throne.

Subsequently, the legitimacy was consolidated and the Yongzhen Reform Group was purged, and the new party of centralized reform Han Tai, Chen Ji, Liu Zongyuan, Liu Yuxi, Han Ye, Ling Zhun, Cheng Yi and Wei Zhiyi were demoted. In the major case in cultural history, Xianzong took advantage of the eunuchs' power to ascend to the throne, and their interests were related, and they formed a consortium, so they could not remove the internal eunuchs, but the eunuchs surrendered to the monarchy during the Xianzong period, and the imperial court consolidated its power and unanimously reduced the feudal domain to the outside world.

In the end, Xianzong succeeded in cutting the feudal domain, and when he was about to start cleaning up the internal eunuchs, he was killed by the prince Mu Zong, the joint eunuch and the wife of the harem Guo Ziyi's military family, and the people who benefited were Mu Zong's mother and son and eunuchs, so the internal hidden dangers rebounded, Mu Zong came to power, and the external feudal reduction fell short.
