After two or three hundred years of collapse, when the Tang Dynasty was about to perish, Tubo was also destroyed.
Li Xuanba didn’t want the Tang Dynasty to spend too much energy on Tubo. He originally wanted to do something while Tubo had not been unified yet, but all the plans he made were defeated by Tubo’s geographical advantage.
Anyone who has been to Tibet in later generations knows that even with the protection of modern medicine, most people will still have serious altitude sickness when they go to the Qinghai-Tibet Plateau.
The Tubo people relied on their geographical advantages to attack the Tang Dynasty as “going downstream”; the Tang Dynasty wanted to attack the Tubo, which meant “going upstream”. The difficulty of the march is not a little bit difficult.
What’s even worse is that Tubo can convert any part of the Tang Dynasty into its own power; after the Tang Dynasty captured the territory of Tubo, it could only retreat to its original place. When technology could not defeat nature, people in the feudal era occupied barren areas and gained more than they could.
The land in Tubo is more difficult to deal with than the grassland. The land control cannot be digested by cutting off the population with your eyes closed. Even modern people are not happy to ask them to teach the Qinghai-Tibet Plateau. Don’t make things difficult for the people of the Tang Dynasty.
Li Xuanba pulled the second brother, who was not even the King of Qin, had no idea that he had thought too far away now, and had discussed for a long time. The young two concluded that the only way for the Tang Dynasty to reduce the rise of Tubo was to blockade.
Tubo’s own resources of one acre of three parts are not enough to make it a powerful country. When Tubo was unable to plunder the powerful Tang Dynasty in the early stage, he accumulated resources from the Western Indian Peninsula.
Why did Wang Xuance destroy the country alone and not have a reward? In addition to the famous generals everywhere in the early Tang Dynasty, Emperor Taizong of Tang was not only a military strategist, but also a strategist. Every battle he fights must see tangible benefits, not for the sake of good looks.
Even though Tubo and the Tang Dynasty were still in the honeymoon period at that time, Emperor Taizong of Tang made troops train in Tuyuhun and other places obviously to prevent Tubo in the rising period. Wang Xuance destroyed the country, but the advantage was that of Tubo, so the Tang Dynasty made a fortune. The Tang Dynasty should not give face to the Tang Dynasty, but the Tang Dynasty should indeed hit India, but this is not the way to hit it.
But this is not Wang Xuance’s fault. There are too few strategists, and there was no concept of “strategy” at that time. Strategists are all born “intuition”. Even when they make decisions, they may not have thought about the causes and consequences themselves, let alone teach others.
If Emperor Taizong of Tang left his own words on strategic thoughts, Emperor Gaozong of Tang and Emperor Xuanzong of Tang would not be so stupid as to help the Turks and Nanzhao unify themselves to rebel against them.
There is no benefit to destroying a country, there is no contribution. This was a reward and punishment strategy in the refusal of war against military gains during Emperor Taizong of Tang, and it was also the reason why he had the advantage in the situation on the battlefield of Goryeo and took the initiative to retreat.
Li Xuanba pulled his second brother to draw circles on the map.
On the Indian Peninsula, the support forces blocked the southwest of Tubo, and it was not possible to achieve it until the second brother became emperor; blocking Tubo from going east to plunder, the key is to control and support the obedient Tuyuhun tribe., They are doing it now; to prevent Tubo from competing with the Tang Dynasty for the important Silk Road in the future, Li Xuanba and Li Shimin turned their attention to the northeast of the Qinghai-Tibet Plateau, the only “East Girl Country” that can form a population gathering place, the Supi tribe.
The core scope under the jurisdiction of the Subi Kingdom is now Yushu City, Qinghai. Because of the connection of large rivers such as Tongtian River and Zhaqu, it is a rare area on the plateau where you can get half-agricultural and semi-animalized. It is a “staircase” for Tubo to leave the plateau.
This year, Songtsen Gampo is three years old. His father, Nangri Songzan, was about to destroy the Subi Kingdom and officially completed the transformation from the leader of the small state in Shannan to the unified king of Tubo.
“San Sister, when you were in Longyou, you had contact with the Eastern Female Kingdom.” When Li Xuanba was in Longyou, he often generously supported the Tubo tribes so that they would not unify too quickly.
Later generations often said that Tubo was strong because Emperor Taizong of Tang asked Princess Wencheng to bring advanced agricultural tools and seeds, which is of course not true.
First, when Emperor Taizong of Tang sent people to send Princess Wencheng to marry, he did not bring craftsmen, but brought silk musicians and other things. Tubo used Princess Wencheng’s marriage to exchange technology with the Tang Dynasty, which was a matter of Emperor Gaozong of Tang.
Secondly, even if Princess Wencheng brought craftsmen and seeds over there, it had little to do with the rise of Tubo. Songtsen Gampo’s marriage with the Tang Dynasty was that he had unified Tubo, plundered the Southeast, and fought a war with the Tang Dynasty but failed. Tubo had seized advanced iron farming technology in the war against the Southeast.
To put it bluntly, there are no trade barriers now. As long as the rulers want to learn, they can learn anywhere they go. Blockade technology is impossible. As long as a place is strong, small and scattered countries around will follow them to eat meat and drink soup.
The prosperity of the Tang Dynasty must have led the surrounding small countries to make a major technological and economic leap. The only thing Li Xuanba can do is to control the order of their rise.
Since we knew that there was a tribe in Shannan, Songtsen Gampo and his son were wise and talented people who were hard to see in the ages, Li Xuanba of course chose the tribes in Shanbei to support him.
