introduction
There is a saying in the "History of Qin Shi Huang Benji": "With the princes as counties, everyone is happy for themselves, there is no danger of war, and it is passed on to all generations." Whether it is to expand the country or to defend the country, war is inevitable, but only when the world is peaceful, the people can live and work in peace and contentment, and the inheritance of mankind can exist forever. However, the greed of human nature cannot make war disappear, and there will be competition where there are people, which has existed since primitive society.
With the development of society, people's combat ability is gradually changing, from the beginning of individual fighting with punches and kicks, to the organization of tribal battles, and then to the later battles between countries and internal strife within the country, it seems that the war is somewhat endless. Especially when people's combat effectiveness is rising and their weapons and equipment are becoming more advanced, human beings are also suffering more and more damage from war.
Like there are countless battles in the history of our country, some of which are to defend against foreign enemies, some of which are also to expand the territory, but there is a war that has nothing to do with our country, but it has given us an additional jurisdiction, and the land area has increased by millions of square kilometers. The war came from a dispute in the Persian Empire. The Persian Empire was one of the few powerful empires in history, and they created the earliest and most splendid Persian civilization.
Although the Persian Empire is collectively known as Persia, there are three eras in which he actually lived. The first era was the Archemenid dynasty, which was probably 2700 BC, and it was not until the second century BC that it was conquered by Alexander the Great to establish the Sabbath Empire, and the second period of the Persian Empire was established after this, when our country was in the Eastern Han Dynasty. A Gan Ying who went to the western region had worked tirelessly to the Sabbath Empire, this era was ruled by the Sassanid Dynasty, they should have been the rulers of the Sabbath Empire, but they subverted the Sabbath Empire, after unifying the full control of Persia, they learned about the Sabbath Empire, established the second era of the Persian Empire, and once again became a powerful empire in Central Asia.
After that, Persia did not settle the peace, and they fought for a long time with their old enemies, the Europeans, and the struggle between the Persians and the Romans was particularly fierce. At that time, Rome was bent on expanding its territory, and even the Roman emperor Valerian personally fought, but this battle Rome lost very thoroughly, and their emperor was imprisoned until his death. A hundred years after this war, another Roman Emperor, Julian, died under the Persian army. Although the persian and Roman battles have always prevailed, the cost of their expenses is not small, and the treasury has been empty after hundreds of years of continuous war, and they have not thought of an armistice at this time, and the cost of the war has been plundered from the people. Therefore, the people of Persia have long resented these rulers and may resist at any time.
At that time, the Sassanid Dynasty seemed to have reached the end of the crossbow because of war expenditures, and no longer had the ability to fight against foreign enemies. Even the Great Wall, which had been built to defend against the enemy, was abandoned, and this large area of land was directly occupied by Arabs and Islam. It was not until 628 A.D. that the Sassanids came to an end, and they began to be crusaded by various countries. At that time, the national strength of Sassanid Persia could not resist these crusades, and they could only accept destruction.
Thankfully, although Sassanid Persia perished, they also left behind a descendant, Bethru, who carried the hope of rebuilding Persia. However, rebuilding Persia was not an easy task, at least the Arabs did not allow Persia to rebuild, and when they saw Thatsrough trying to start a war, the Arabs directly defeated it. He asked for help from the Tang Dynasty in our country at that time, but Tang Gaozong at that time did not agree to Beisi Road, because the Tang army stationed in the western region at that time was only 20,000 people, although it was an elite force, but in the face of the powerful military forces of other countries, these 20,000 people were simply not enough to see. However, after rejecting The Road's request to send troops, he also made another account to The Road, that is, the Road of The Road was made the Governor of Persia by Emperor Gaozong of Tang, and used the power of China to open up a territory for these Persians, so that the Road of The Road could take in his Persian fugitives.
epilogue
Since then, the Tang Dynasty has gained millions of square kilometers of territory for its help to Persia, located in present-day Afghanistan and eastern Iran. Although all the people living on it were Persians, it was essentially the territory of the Tang Dynasty at that time. This group of Persians living in this land did not want to recover the lost land of the past, but because their combat effectiveness and military level could not restore the strength of the previous Persian Empire, they have also failed. And Beslu, who led these restoration wars, remained in Chang'an until his death, and he did not return to his hometown, and the homeland of the Persian Empire was occupied by Islamic rule.
