In the thirteenth century, China was in a small period of low temperature, the grassland environment began to become harsh, in order to survive, coupled with the exploitation of the Jin State, in order to survive, the major tribes on the Mongolian Plateau began fierce competition and annexation.
And the tribe of Temujin was the victor in this melee, and for the first time, the survival of the fittest, and the strongest fighters on the steppe survived in a group. Next, they ushered in an important opportunity, the Northern Expedition between the Jin State and the Southern Song Dynasty, the cost was huge, and the military strategy of the Jin State also began to be conservative, which was directly reflected in the military strategy of the Northern Front troops of the Jin State. Mongolia has more room to play.
So there was the Battle of Yehuling, and the whole line in the north of the Jin Kingdom was lost, and most of the war horses were. The Mongol army, which had obtained a large number of war horses, further improved its tactics, and various tactics that greatly depleted the physical strength of war horses were born. It became more and more difficult for the enemy to defeat and annihilate the Mongol army in the field. After that, in order to conquer the Jin Kingdom, they began to seek wealth in the west.
Defeated the Western Liao first, and farther away, they originally pinned their hopes on **, but as a result, Khorezm relied on himself to be the boss of the Islamic world, and directly robbed Mongolia without anyone. Then Mongolia will naturally start to rob directly. It turned out that the most capable troops in Central Asia were actually the Khitans, the competitors of the East Asian monster house. Under this kind of gap in combat strength, Harazimo made a defensive strategy mistake similar to that of Jin Guo, and the end was naturally very miserable.
In this westward expedition, Mongolia gained more advanced siege equipment and a lot of wealth, and once again made up for the shortcomings. At this time, it can be said that the combat power of the Mongol army in the period of Temujin had already taken shape. It can be seen that under the condition of accurately grasping the opportunity for development, such an army was rolled out in the involution of the East Asian monster house.
