Why did the Buddhist civilization in the western regions, which lasted for thousands of years, die out?

On today's border between Kazakhstan and Kyrgyzstan, there is an ancient river flowing from east to northwest, which is the Taras River. This river, which is only more than 500 kilometers long, seems a little insignificant, and it is even difficult for people to find its shadow on the general map of Central Asia. In the plain area on the left bank of the middle reaches of the valley, there is an ancient city named after it, which has a history of more than two thousand years-Talaz (translated as "Neros" from the Tang Dynasty). In 75 1 year (the tenth year of Tang Tianbao), an unprecedented war took place here. One of the warring parties is Tang Jun, who is guarding the western regions led by Gao Xianzhi, and the other is the Dashi (Arab Empire) army led by General Ziyad. ...

The year before the Battle of Milos, that is, in 750 AD, the influence of the Tang Empire in the interior of Asia reached its peak. As recorded in the History as a Mirror of later generations, "China was strong at that time, and the Tang Dynasty was 22,000 miles west from Anyuanmen, facing the Yan State and Sangmaye, and the world was as rich as Longyou". Tang Empire became the master of the whole Tarim Basin and Yili Basin, the suzerain of Tashkent and the protector of Pamir Valley and Kashmir. As an envoy of Anxi, Gao Xianzhi, a famous Tang Dynasty soldier, just went deep into Wan Li on the Pamirs and made great achievements. He won a series of amazing victories against the Tubo forces and won the reputation of "Mountain God of China" in the west. Unexpectedly, the lingering sound of Tang Ting-kai's ceremony, the border alarm has spread thousands of miles, flying to Chang 'an. Gao Xianzhi's army plundered the Stone Kingdom, killed the old and the weak, and enslaved Ding Zhuang, which led to new incidents. The prince who narrowly escaped ran to the "Nine Surnames of Zhaowu" and praised Tang Jun's cruelty and "All Hu people are angry". Then he went to Guo Kang (Samarkand) to meet Ziyad Sari, the big food general who led the army.

In 750 A.D., the ruler of the Tang Dynasty, citing the "impoliteness" of Shi Guo, a vassal state in the western regions, led the troops to conquer Gao Made, Shi Guo demanded surrender, and Gao Xianzhi promised to make peace. Soon, Gao Xianzhi broke his promise, occupied and bloodbath Shiguo City, swept away men, killed old people, women and children, searched property, and seized the king of Shiguo. In the first month of 75 1 year, Gao Xianzhi entered the DPRK and presented the captured king to Xuanzong. He was awarded General You Yulin for his outstanding exploits and beheaded the stone king. At this time, Gao Xianzhi reached the peak of his career. The prince of the stone kingdom, who escaped by luck, turned to the Abbasid dynasty (black food) for help. Gao Xianzhi pre-empted, took the initiative to attack and eat. Gao Xianzhi led the allied forces in the Tang Dynasty to make a long-distance raid, which lasted more than 700 li. Finally, he met a big food army in Juros.

The beginning of the war of heroes is strange. Tang Jun crossed 700 Li to attack the Afghan army in the city of Helos, and the attack was very hasty. This is because Tang Jun's Commander-in-Chief Gao Xianzhi (Korean) thinks that Milos has only a few thousand Arab soldiers, and he can quickly win Milos city by his own long-distance attack, and then he can stop the exhausted Arab reinforcements coming from the west at the edge of the desert at the exit of Fergana Valley. But the reality is that there are 40,000 Arab troops stationed in the city of Heros, and another 65,438+10,000 Arab troops crossed the desert and approached the city of Heros.

Under the command of Gao Xianzhi, Tang Jun officers and men fought bravely. With the constant array impact of knife-wielding infantry and giving full play to the advantages of strong bow and hard crossbow, Tang Jun completely gained the upper hand at the beginning of the war; With the close cooperation of infantry and crossbowmen, the cavalry troops in the Tang Dynasty once suppressed the Arab cavalry, which was famous for its bravery and good fighting.

In the fierce fighting that lasted for several days and nights, Tang Jun caused great casualties to the officers and men of the Grain Army, and the history books recorded the brilliant record of "wiping out tens of thousands of enemies"! However, due to the large number of Arab Coalition forces participating in the war, Tang Jun, which is completely at a disadvantage in number, has never been able to effectively annihilate the enemy. The battle has entered a stalemate!

On the evening of the fifth day of the campaign, the mercenaries in Tang Jun suddenly rebelled, surrounded the Tang Jun infantry from behind and blocked their contact with the cavalry. Tang Jun was in a state of chaos! The Arab Coalition forces took the opportunity to dispatch heavy cavalry to attack the formation center of Tang Jun. Gao Xianzhi debacle, twenty thousand Anxi elite troops to break through a bloody battle! The direct consequence of the Pilars War was that the Arab Empire completely controlled Central Asia, and Central Asia began the process of islamization as a whole, and the Han and Tang civilizations that lasted for thousands of years in the western regions began to fade out of this region. Since then, the Buddhist countries in the western regions have gradually disappeared in the dust of history.
