Datang's force is unparalleled in the world, there is no doubt about this, if he is not chaotic, no enemy next to him can pose any threat to Datang.

Datang not only has a strong military, but also has no political means of struggle that others can match.

In September, Datang gave a good lesson to the somewhat swollen Xue Yantuo people.

Since the extermination of the Eastern Turks, the vast grasslands have become grazing lands, livestock, and wool supply bases for the Tang Dynasty.

The occupied grassland is large enough, and the supply can also meet the needs of the Tang Dynasty, so the military strength of the Tang Dynasty is not much deployed on the grassland, and then the grassland people in the territory occupied by the Tang Dynasty are basically deprived of their armed forces.

The knives, bows and arrows and other weapons at home are recorded, and the number of kilometers prescribed by the imperial court cannot be exceeded, and the size and pasture of each tribe are divided, and the large tribes are all broken up into small tribes, and then placed separately.

And if the tribal population increases beyond the quota, it is necessary to continue to divide and disperse.

In this way, it is ensured to the maximum that these grassland people do not have enough strength to threaten the Tang Dynasty. Of course it's not just such checks and balances.

Enwei and the original dynasty, not to mention the ruler, but anyone who reads a little book understands this truth.

Although the Tang Dynasty not only understands, but also does so, although the grassland is defined as a breeding and supply base for raw materials, the Tang Dynasty does not exploit the herdsmen on the grassland excessively.

The Tang Dynasty treats herders as if they were truly their own people, rather than slaves who can be plundered at will.

The rights enjoyed by herdsmen are the same as those of the people of the Tang Dynasty, and the taxes are all the same, of course, the rights are the same, and the obligations are also the same, such as abiding by the government military system of the Tang Dynasty, and those who meet the conditions must be conscripted, and the rotation of the garrison.

The military government that governs them, according to the distance, there are Shuozhou, Yunzhou, Xiazhou and other former border towns that belong to the military government, and they are all scattered after entering the military government, and they will not be allowed to form gangs according to tribes and ethnic groups.

This approach is to convey to these people that we are all the same, and there is no mental hint that we are treated differently because of our status as herdsmen, so that they can have a real sense of belonging to Datang. Second, it can also improve and reduce the combat effectiveness of grassland herders.

After all, the government soldiers who were conscripted were all in good health, or at least among the most powerful people, and they were conscripted and left their hometowns for at least months, or even years.

And then they rotate again, and when they go back, someone else will be taken away.

Suppose that the young and middle-aged people of a tribe are thousands, because the government soldiers are rotated and recruited, and 200 people are transferred each time, then the real young and middle-aged people of this tribe are only 100, and there are often 200 fewer people, and the combat effectiveness will inevitably be greatly reduced.

The whole calculation is equivalent to the combat effectiveness on the grassland has been removed by 20%.

It not only increased the sense of belonging of the grassland herdsmen, but also increased the number and strength of the Tang army, and by the way, weakened the strength of the grassland herdsmen.

But the strength of the grassland is not only good, but also has many disadvantages, that is, another grassland country, Xue Yantuo always covets the neighbor's land, cattle and sheep and women.

On the grassland occupied by the Tang Dynasty, because the cattle, sheep and horses, as well as the wool produced are sold to the hinterland of the Tang Dynasty, the herdsmen's living standards have been rising steadily in recent years, but their force is not strong.

On the contrary, Xue Yantuo, since the war between the Tang Dynasty and the Eastern Turks, Xue Yantuo took advantage of the fire to rob and snatch the fruits of the victory of the Tang Dynasty, and was taught a hard lesson by the Tang Dynasty, and after spitting out everything he ate in his mouth, Xue Yantuo has a grudge against the Tang Dynasty.

In the past, the Eastern Turks were the most powerful on the grassland, and Xue Yantuo was the younger brother, and after the Eastern Turks were destroyed, Xue Yantuo became a country that could control his own destiny from the younger brother, and was canonized by the Tang Emperor, so it was still justified and could attract other tribes to vote.

Then the Tang Dynasty had no intention of developing and deploying force on the grassland, and the herdsmen under its jurisdiction were also greatly restricted, which caused Xue Yantuo's family to dominate and became the de facto boss of the grassland.

After the annexation and encompassing other tribes such as the Hui and the Servant Bone and the Xi people on the grassland, Xue Yantuo became more powerful, but the increase in power did not have the matching economic and financial resources.

It can be said that Xue Yantuo's strength is deformed, and there is no opponent in the grassland militarily, but the economy is still very primitive, and self-sufficiency cannot be done.

So Xue Yantuo, who didn't remember to eat or fight, started to think crookedly again, and they targeted the herdsmen of the original Turks and other tribes in the Tang Dynasty occupied area.

In their minds, Datang did not deploy heavy troops on the grassland, which means that Datang does not attach much importance to this place, but just needs cattle, sheep, horses and wool on the grassland.

Then we can also provide these things to Datang after we occupy it, as long as Datang still pays as before.

With this in mind, they attacked two Turkic tribes on the other side of their border and took possession of them.

The Tang Dynasty didn't think about fighting them, but just sent people to reprimand Xue Yantuo Khan, and asked them to return the land and people and property they occupied.

Later, Xue Yantuo just let go of the herdsmen of the two tribes that were robbed, and the land and property were not returned, so the Tang Dynasty didn't look at it much, and resettled the herdsmen of the two tribes, and this matter was let go.

Unexpectedly, Datang's generosity was thought by Xue Yantuo that what he thought was right, but Datang didn't pay attention to the grassland.

With this thought, the people of Xue Yantuo strengthened their determination to invade and occupy the grassland to which the Tang Dynasty belonged.

In just one year, more than a dozen tribes and grasslands have been occupied by the Xue Yantuo people, and the Tang Dynasty monarchs and ministers are very angry, no matter how generous they are, they are not so generous, the key is really annoying, today this is occupied, and tomorrow there will be problems there.

Nima's Lao Tzu couldn't read the newspaper just by reading it, and the officials sent to reprimand it were all rotated quickly.

So Li Shimin, who was very angry, and all the ministers of Zaifu held a small court meeting, and after discussing it for half an hour, they came up with a solution.

Or not ready to use force to fight, the way is to start from politics, divide and provoke, and support confrontation.

To put it simply, Xue Yantuo Khan Yinan has two sons, and originally the only one who inherits the khan is his son. But the Tang Dynasty court went down and canonized Yi Nan's two sons as khans.

Moreover, these two sons canonized Khan, and the power tribes were divided from Yi Nan.

Originally, the position of Khan should have been passed down after the death of Yi Nan's son, but after the Tang Dynasty, Yi Nan was alive and his two sons had already become Khan.

directly divided Yi Nan's rights, the key is that no matter whether Yi Nan will divide the rights or not, his two sons nominally have that part of the rights.

The father and son are directly in a state of struggle for power and profit, the father has to prevent his son from usurping power, the son has to guard against being killed by Lao Tzu, and the two brothers are also guarding against each other.

A small way, it is easy to divide Xue Yantuo's superstructure, the upper layer is divided, and the three people below have their own forces, so they are naturally divided and hostile.

Li Shimin played a game on Xue Yantuo Yi Nan and his son and the three of them plagiarized from Emperor Wu of the Han Dynasty.
