There was a political economist in the West named Malthus, who once put forward a famous theory.

The development of the population possessed by a civilization cannot exceed the level of agricultural development, and once it does, the excess population must be wiped out in some way.

The history of the rise and fall of countless civilizations from ancient times to the present day proves this theory.

This theory is known as the "Malthusian trap" or "Malthusian disaster" or, more directly, the "population trap".

The occurrence of war can always take many lives and bring great suffering to the survivors, so people have criticized the war, rejected the war and even wanted to destroy the war, but most of the wars may not be driven by the greed of some people, but the existence of people themselves.

For most of history, population growth has outpaced productivity growth, and all of this has been driven by climate, especially for the land of China.

In the warm period of history, the grain in the fields grew much longer, both the nomadic herders of the north and the farmers of the south could eat their stomachs, the necessary factors for waging war did not exist, greed and desire were not enough to cause a full-scale war, but once it entered the ice age, war was inevitable.

A large number of people accumulated in the warm period could not get enough food during the ice age, and under the constraints of productivity and climate, food production was not enough to feed so many people, so if they did not fight or plunder, they would starve to death.

And this dilemma also exists in the current Jurchen tribe.

The Jurchens are a fishing and hunting people, living by fishing and hunting, because they are close to the Han land, so there are also Jurchen tribes who have learned the way of farming, and over time, many of the Jurchen groups also rely on cultivating the land to support themselves.

Farming, hunting, fishing, gathering, and living and thriving on this land are relied on as a way of life.

How low the intensity of this mode of production is, that is, it is conceivable, in the past, because of the lack of unity between each other, there were often frictions, large and small, wars were not uncommon, and the level of population and productivity between the tribes barely kept up.

However, in the last six or seven years, because of the intervention of the Han people and the strong pressure of Li Rusong, the major Jurchen tribes began to increase their population.

This was a good sign, they needed strong soldiers, but as the population grew, they gradually found that there was not enough food to eat, no matter how hard they hunted and fished, they still felt that there was not enough food to eat.

This situation made them very incomprehensible and terrifying, and hunger was enough to make anyone frightened.

The seeds of war began to brew quietly.

There were great conflicts between the tribes because of the land, grain, prey, and rewards of the Ming Dynasty.

It wasn't until the Great Qin Dingding, Li Rusong was transferred, the Liaodong Army was divided as a whole, and the external oppressive forces were changed, and they were already ready to move, but they didn't know the policies of the Great Qin government, so they didn't dare to mess around, but after the Great Qin government opened the arms ban to them, this situation changed.

Some people can't wait.

And the first person to cause trouble was not Nurhachi, but the Haixi Jurchen Division, who had long wanted to kill Nurhachi.

Nurhachi started with the power of a small end, which can be regarded as a counterattack by Jurchen civilians in a sense, so he has always been despised by the Haixi Beylers who consider themselves to be "famous in the world".

But with Nurhachi's unification of the state, his power grew stronger, which finally caused the Haixi Nuzhen to be uneasy.

Hadabel Huergan, Yehebel Nalimbulu and others tried to control Nurhachi by marrying, and blackmailed Nurhachi several times in an attempt to coerce him to cede land to limit the expansion of the Jianzhou Jurchens, but Nurhachi sternly refused.

After the non-war means lost their effectiveness, Narinbulu and others decided to no longer sit back and watch the development of Nurhachi, but to eliminate him, so in the twenty-first year of Wanli decided to jointly attack Nurhachi, as a result, Nurhachi was recruited by the Ming court to go south to assist in the attack on the Japanese Kou, Nurhachi Jianzhou Wei was protected by Li Rusong, and the Haixi Jurchen did not dare to fight with the famous Li Rusong, so they could only stop the army.

In the following years, Narimbulu and others had a slight friction with Nurhachi, but because of the intervention of the Ming court, the battle could not be fought, and it dragged on for six years.

But this time, there is no one to stop it.

Narimbulu could no longer resist the urge to make a move on Nurhachi.

So after returning to the territory with the weapons obtained from the trade and arming the soldiers, he immediately rushed to the territory of Jianzhou with them, looted a cave, killed more than 100 people, captured more than 300 people, swaggered back to his territory, and then spread the news to the Jurchen tribes in Haixi.

When Nurhachi returned to Hetuara and learned of the news, he was furious and immediately sent someone to ask Narimbulu why he had reneged on the covenant, Narimbulu's sister was Nurhachi's wife, and the two could be counted as a little kinship, but this kinship was insignificant compared to the interests of the clan.

Narinbulu lightly prevaricated Nurhachi's messenger back, which made Nurhachi even more annoyed, and after discussing with He Heli, Nurhachi directly sent troops to attack a cave under Narinbulu's jurisdiction, an eye for an eye.

This angered Narimbulu, and Narimbulu immediately prepared to send troops to fight back, and at this time, Narimbulu received news from the Huifa Division, the Ula Division, and the Hada Division, saying that their three divisions were willing to unite with the Yehe Department and attack Nurhachi's troops.

After several years of recuperation and recuperation, the four departments of Haixi have all possessed strong strength, and after having such a strong strength, the four departments of Haixi naturally want to expand outward.

The first target is to make them very unhappy to establish the state of Nurhachi.

So Narimbulu stopped sending troops, and immediately replied to the three departments, asking them to send troops to help, and strive to level the Jurchen tribe of Jianzhou in one fell swoop, and get rid of Nurhachi, a henchman.

What is it, but he dares to call himself Shule Belle.

The nobles of Hercynian Belle decided to make Nurhachi history.

And this news was learned by the Black Water secret agents hidden inside the Jurchens, so the news was quickly sent to Liao Zhong and Ma Chong, and at that time, the four departments of Haixi had not yet gathered.

After Liao Zhong and Ma Chong learned that the Jurchens were about to start a civil war, they immediately became vigilant, they realized that this was a good opportunity to observe the Jurchens' combat methods and understand the strength of the Jurchens, and they wanted to know why His Majesty the Emperor was so jealous of a group of barbarians.

They immediately demanded that the spies accurately convey to them all the internal movements of the Jurchens.
