Mongol Empire (Note 1)
Birth and childhood
Born in 1161 in the Mongol Beggars, because his father also quickly captured the tatar chief Temujin Wuge named Temujin; in 1170, he was related to Temujin, whose father was poisoned when he returned to the tribe, and the tribe was torn apart, he also changed from a young master of the group to a low-level person, Temujin's mother and son lived a life of upheaval and displacement, and it was this environment that cast Temujin's resolute and courageous character.
Unify Mongolia
When Temujin became an adult, he thought that he still had a family affair, so he went to his father-in-law to propose to him, and then recognized his father's Anda and The leader of the Krie tribe, Wang Han, as his father (Note 2), helped him collect the old part, and then rebuilt the Qiyan tribe. Around 1182, when the Qi'er Beggars raided the Qi'an Tribe and captured most of the tribesmen, including his wife, Temujin asked Wang Han and the Mongol Zada nobleman Zamuhe to defeat the Qi'er Beggars and unite with Zamu to form Anda, and the Qiyanbu grew and grew.
Seeing the gradually growing Qiyan tribe, Zamu joined forces with more than 30,000 troops to attack Temujin, and Temujin was defeated, known in history as the Battle of the Thirteen Wings. After this battle, due to zamuhe's wrong decision, the people defected to Temujinbu, and Temujin's strength was not weak, but rose; in 1196, Temujin was rewarded for helping the Jin Dynasty put down the rebellion, and he had great righteousness from then on. In 1202, Zamuhe gathered various forces to attack Temujin, temujin and Wang Han defeated the enemy, and Zamuhe surrendered to Wang Han.
The growing Temujin caused dissatisfaction among his allies Wang Han, and finally in 1203 the Battle of Hezhen Shatuo broke out; Temujin was outnumbered and retreated to the Juni River; after receiving news that Wang Han's defense was unguarded, he raided Wang Han's tent, and fought fiercely for 3 days and nights to defeat Wang Han's troops and conquer the Keliebu under his command. From then on, the cause of Temujin's hegemony was laid, and in 1204, the Naiman tribe of sun khans in the western part of the desert was destroyed, and then the last powerful tribe, the Qi'er Begbu, was destroyed, and Mongolia was officially unified.
