The prosperity of the Tang Empire, in fact, do not need us to comment too much, after the establishment of the Tang In 618 AD, has been in his proud posture, straddled in the East, almost all the countries in the world at that time can only look up to his existence, but it is difficult to imagine that the Tang Empire in the foreign war, there is also its own side of the wolf, of course, this also has a lot to do with the rise and fall of the ancient feudal dynasty, after all, a feudal dynasty always has to go through a process of rise and fall.
This brings us to the Arab Empire, the Predecessor of the Arab Empire, the Arab nation, itself a nomadic people, the religious unity of Islam at that time under the spread of Muhammad, has formed a certain scale, almost 100 years before the establishment of the Tang Dynasty, the Arab nation led by Muhammad established an Arab Muslim country, that is, the later Arab Empire.
In this hundred years, the Arab Empire continued to expand, and gradually formed a large country spanning the three continents of Asia, Europe and Africa, covering an area of 13.4 million square kilometers, the prophet's heirs of the four caliphs in their forced expansion of the territory, they destroyed countless countries, from 654 AD, the Arab expansion occupied the central Asian countries, that is, our Tang Dynasty western countries, and even almost crossed the Pamir Plateau, war with China, but at that time may also be worried about something The two sides only had a brief contact and then withdrew, but the Arab Empire never eliminated China's ambitions, and under the expansion of its ambitions, in 709 AD the Arab army crossed the Pamir Plateau and attacked the Tang Dynasty's Anxi Capital.
But the Arab Empire also underestimated the strength of the Tang Empire in the Anxi Capital Protectorate, this battle was fought, the Arabs almost lost their armor and fled, and the troops used by the Tang dynasty at that time were only the 10,000 troops stationed in Bahena by the Anxi Capital Protectorate plus the turmoil within the Arab Empire later, which could have taken advantage of this to compete for control of Central Asia, but at this time Tang Xuanzong Li Longji had already lost his former ambitions and pride, and finally died without any problems.
In 751 AD, after the Arab Empire resolved its internal strife, it made a comeback again, and Li Longji sent Gao Xianzhi to lead a large army plus Gelulu's troops to fight a decisive battle with the Arab Empire, this time due to the rebellion of the Gelug people, Gao Xianzhi, although brave, could not stop the front and back attacks, and finally the army was defeated by the Arab Empire.
Of course, this battle is recorded differently in different historical materials, some say that the Arab Empire wants to capture the four towns of Anxi, Gao Xianzhi and its decisive battle, there are also said that Gao Xianzhi decided to preemptively attack, so the result of sending troops to attack Arabia was ambushed, but in combination, this battle Gao Xianzhi lost tragically, the entire army was destroyed, only more than a thousand people fled back, but after this battle, Arabia no longer dared to take the initiative to attack Datang, and did not dare to use troops for more than 100 years
