As a powerful dynasty in history, the combat effectiveness of Tang Dynasty soldiers is indeed very strong, especially in terms of foreign wars, the Tang Dynasty's army also rarely suffers defeats, we think of such a problem, Tang Dynasty materials are rich, so foreigners must be very red-eyed, so the frontier wars in the Tang Dynasty period are also continuous, but there is only one nation, which has become a stain in the Tang Dynasty's military, this nation is Tubo, Tubo has also become the only ethnic minority to invade Chang'an City.
Many people are curious why it is said that the Sheng Tang Dynasty and the Sheng Tang Dynasty can't even beat a small Tubo, in fact, I think the reason for this problem exists on both sides. Tubo is located in a remote and cold place, so the land in that place is also relatively barren, so they naturally look at the land of datang, and in exchange for other ethnic minorities, in fact, they will do this, because everyone yearns for a better life, and as they can only conquer the lands that make them yearn for by force.
But Tubo is not stupid, in the face of the powerful Tang Dynasty Tubo did not screw with the Tang Dynasty like the Turks, but adopted a policy of recuperation, it can be said that songzan Gampo's influence on Tubo is very large, and he is also a ruler with quite insight and leadership, for the powerful Tang Dynasty, he first led the tang dynasty to let the Tang Dynasty people see the combat effectiveness of the Tubo army, in fact, his purpose is not to fight, but to negotiate conditions, so Princess Wencheng went, the two sons lived a very good life, more than ten years, the Tang Dynasty and Tubo were at peace Tubo, on the other hand, has developed rapidly and become more and more powerful in more than ten years, so they gradually have the combat strength to compete with the Tang Dynasty, so the strength of Tubo is directly related to Songzan Gampo.
Later, Tubo finally sent troops to fight the Tang Dynasty, and also took advantage of the turmoil in the Tang Dynasty's domestic situation to march all the way to occupy Chang'an City, so Tubo was considered to be a head-on confrontation with the Tang Dynasty? I don't think so, or even that Tubo has never really had the courage to stand up to the Tang Dynasty, because the support behind it is obvious.
Later, Tubo used his military strength to gradually swallow the Tang Dynasty's land in the west, and the Tang Dynasty's military strength at this time was not so strong, coupled with the western battle, the battle line was too long, so it was easy to have the problem of cutting grass and grain, so the ruler also turned a blind eye, I think this is also an important reason why Tubo can win victories.
