First of all, the Jin Kingdom did not collapse when the Mongols conquered huazimo in the west, but the Territory of the Jin Dynasty gradually decreased and the resources became more and more scarce and was forced to Fenjing. By this time they had developed a fear of the Mongol army, and annihilation was imminent. At this time, Hua Lazimo actually took the initiative to provoke the affairs to make genghis Khan, who was very talented, angry, and the result was naturally very sad.
In 1218, Genghis Khan sent a large caravan to the west to prepare to exchange jewelry and medicinal herbs for food and horses, and then launched another attack on the Jin Kingdom to destroy it once and for all. But the local governor saw the wealth and killed the caravan and swallowed the property. Genghis Khan sent envoys to write to him for treachery demanding the surrender of the murderer, while the nouveau riche Hua Lazimo proudly refused and killed the Mongol emissary. This made Genghis Khan angry, although according to the plan, it was not yet the time of the expedition to the flower-la-la-mold, but he also had to do his best. At this time, the Jin Kingdom was completely in trouble under the attack of the Mongols and Song Dynasties, and the meat that became the mouth of the Mongols would be eaten in the mouth sooner or later. However, the Golden Kingdom still has a nominal army of 300,000, and if it is forcibly destroyed, the lethality of the Golden Lady's True Beast Fight is equally amazing. Therefore, in order to avoid Mongolia from suffering heavy losses, it is better to take the opportunity of the western expedition to leave a partial division to slowly consume the strength of the Golden State. Therefore, Temujin entrusted the responsibility of defending the Jin Kingdom to Muhua Li to personally conquer Hua LaziMo, and the Mongol Western Expedition hua zi mound was not a deliberate affair but was fully prepared.
The Mongol attack was carried out in conjunction with the Southern Song Dynasty, so it was not a great loss when attacking Jin. Let's look at the territory of the original Jinguo (as shown in the following figure): In addition to the lack of cold and products in the north, the south is a rich land in the Central Plains, and the products are abundant. Comparing the upper and lower figures, it can be seen that the Mongols occupied a lot of rich lands, and according to the nature of the Mongol captives, they must have earned a lot of money, so there should be no small losses. Therefore, Jin Guo was able to survive thanks to the flower thorn mold. Before his rise, Hua Lazimo has always been the existence of being a little brother to people. This tragic history began in the sixth century BC and was ruled by the Persian Empire, the Kushan Empire, the Arab Empire, the Seljuk Empire, and the Western Liao Empire. It was not until Mahamad was king that he developed into a Central Asian power, and it was because of this inflated psychology that his subordinates would be allowed to slaughter the Mongol caravans and loot property. But he did not realize that the empire that had survived for hundreds of years to emerge would be destroyed by the plundering of Mongol caravans.
In 1219, Genghis Khan led an army of 200,000 to begin the first western expedition, which began the war of annihilation of the country by annexing Khwarazm. Genghis Khan's four sons and the generals Subutai and Zhebei went out with the team, which can be said to be elite. The following year, Lamarham, the capital of Khwarazm, was captured, and the emperor of Khwarazm, Arauddin Mahmud, fled west and was pursued and killed by the Mongol army. Therefore, the Mongolian army went west to the Caucasus and penetrated deep into Russia, which allowed Mongolia to expand its vast territory. It can be said that the Khwarazm contributed a lot to the laying of the Mongolian territory. After Mahamad's death, his son Zalandin raised the banner of rebellion against the Mongols, and in a decisive battle on the Banks of the Indus in 1221, Zalandin's army was completely destroyed and only 4,000 followers fled to India. Genghis Khan divided the territory and newly conquered lands among his four sons, and Genghis Khan left his eldest son Shu Chi Zhen ShouHua Thorn Zi Hou Ban Shi. The first western expedition of the Mongol army brought the Mongol power deep into Central Asia and Eastern Europe, and the four khanates gradually took shape.
