The Tang Dynasty once faced Persia for help, why didn t it lend a helping hand?

The Persian Empire was established in the sixth century BC and lasted for a thousand years. By the time of the Tang Empire, the Sassanid Dynasty of the Persian Empire was already in turmoil, and had been competing with the Eastern Roman Empire for the power of the Persian Gulf for many years, exhausting its financial resources, coupled with the frequent attacks of the emerging Arab powers. The Sassanid Empire of Persia was decliningUnder these circumstances, Persia sent people to ask for assistance from the Tang Dynasty three times, hoping that the Tang Dynasty could conquer the Arabs in the west and help them restore their former rule.

At this time, the ruler of the Tang Dynasty was Tang Gaozong Li Zhi, and under his rule, the territory of the Tang Dynasty reached the largest in the history of the Tang Dynasty.

The powerful Tang dynasty rejected the Persian dynasty's request for several reasons. The first reason is that the labor expedition is difficult to supply. If the troops of the Tang Dynasty marched westward, it was impossible to trek thousands of kilometers without more than 100,000 troops, and the army of the Arab Empire at this time was at its peak, so it was impossible to have fewer people.

The nearest to Persia is only 20,000 or 30,000 troops in the Tang Dynasty Anxi Protectorate, and the daily garrison is okay, if the labor expedition has to pass through the desert, the Gobi, over the green mountains and other uninhabited areas, it is not possible without logistical support, and once the war starts, it will definitely not stop in a short time. No matter how strong the strength of the Tang Empire is, if you want to go on a long-term labor expedition, military supplies are astronomical, which is difficult to afford

At this time, the Western Regions under the control of the Tang Dynasty were not peaceful, and there were still small countries in the Western Regions that the Western Turks and the Tang Dynasty were competing for, and the emerging Tibetan forces in the southwest posed a huge threat to the Tang Dynasty. Therefore, at this time, the Tang Dynasty was too busy to take care of itself, and it was impossible for him to draw out his forces to deal with the Arabs and help the Persian prince restore the country.

Although the Tang Dynasty did not give direct military help to Persia, the Tang Dynasty still set up the Persian Governorate, and still had a good relationship with the remnants of Persia, and finally the Persian prince died in Chang'an.

Because the leaders of the Tang Dynasty felt that there was no benefit in helping Persia, it cost the people and money, and at that time, the Tang Dynasty was still facing the invasion of other countries, and they were still too busy with their own affairs, how could they have the energy to help Persia!

At that time, transportation was not well developed, so it was hindered by traffic problems.

The Tang Dynasty did not send troops to aid Persia, which is reasonable and reasonable, and there is no need for him to go all the way to help others out, only the honest development of his own strength is the most important. After Persia did not receive assistance from the Tang Dynasty, it was quickly wiped out by the Arabs, and the once powerful Persian Empire was drowned in the torrent of history.

The distance is too long, and the cost is too high; The Tang Dynasty also fought against the Turks and Tuyuhun, and did not have spare troops to support Persia; The army of the Tang Dynasty may not have been an opponent of the Arabs.

Because Tang Taizong was in power at that time, he was relatively close to the people and loved the people, and the distance between Persia and Tang was relatively far, Tang Taizong didn't want his soldiers to be tired, and he didn't want to put his country in dire straits, so he didn't help them.

Because of the distance problem, no matter how powerful the huge army is, they are afraid of the distance problem, and once they travel a long distance, they will lose the combat effectiveness of the soldiers, so the Tang Dynasty did not help Persia.

Because the Tang Dynasty was too far away from Persia in Central Asia, if you want to go to war, the long journey and logistical supply are huge projects, and it is difficult to keep fighting.

Because of the long distance, the logistical pressure is huge. In the ancient world, the expedition of laborers was a taboo for soldiers. Even if the Tang Dynasty sent troops to Central Asia from the northwest territory, the journey was thousands of miles away, and the cost was too high to outweigh the losses.

Asking the Tang Dynasty to help our country rejuvenate, the three requests for troops before the fall of the Persian Empire are really true. The Tang Dynasty was the most powerful period in the world, and many countries made friends with the Tang Dynasty and wanted to seek the blessing of a powerful country, and the Persian Empire was one of them. The Persian Empire was a thousand-year-old country that was later defeated by the Arabs, and since then this thousand-year-old country has perished.

The princes of the Persian Empire asked the Tang Dynasty for help three times。In the twelfth year of Zhenguan, Persia sent envoys to contribute some treasures to the Tang Dynasty, because the Persian king was cowardly by nature, he was chased by the great leader and was ready to flee to the country of Tuhuo, and the king of Persia was killed by the Arabs before he reached the country of Tuhuo. The son of the king of Persia himself fled to the country of Tu Huo, and he asked envoys to come to the Tang Dynasty to ask the Tang Dynasty to help him, but Tang Gaozong refused, but fortunately the Arabs did not enter the country of Tu Huo, and the Persian prince was spared.

In 661 A.D., the Persian prince turned to the Tang Dynasty for help, saying: "The Arabs have invaded their land again. ”At this time, Tang Gaozong was about to govern the Western Regions, so he decided to establish the Persian Governorate and appointed the Persian prince as the governor.

Later, the Arabs captured the city. Since then, the Persian Governorate has existed in name only, and the Persian prince fled to the Tang Dynasty more than ten years later, and Tang Gaozong named him the general of the Right Military Guard.

In 679 A.D., the Tang Dynasty asked the servants to send the son of the Persian prince, Nineshi, back to Persia, but because of the long journey, the servants sent him to Broken Leaf City and let Ninishi take people back to Persia by himself. Later, Ni Nishi and his party stayed in Tochar for more than 20 years, and in the past 20 years in Tocharia, they have gone their separate ways. Seeing that there was no hope of recovering the country, Ni Nishi fled to the Tang Dynasty, and Tang Zhongzong appointed him as General Zuo Weiwei.

There is indeed such a thing, and the Tang Dynasty at that time was very prosperous.

There is indeed such a thing in history, and the ancient Tang Dynasty was very powerful.

It should be true, but it was rejected by my Datang three times.

It should be fake, after all, more than half a year has passed since the Tang Dynasty to Persia.
