Yizhixie

Yizhixie (; r. 126–114 BC) was the brother of Junchen Chanyu and his successor to the Xiongnu throne. Yizhixie ruled during a time of conflict with the southern Han dynasty under the military expansionist, Emperor Wu of Han (r. 141–87 BC).

Defeating Yudan

Originally the Eastern Luli-Prince, Yizhixie, a younger brother of Junchen, had to stage a coup against the previous chanyu's son Yudan, the Eastern Tuqi (Wise Prince, 屠耆). Yudan was defeated by Yizhixie in battle and fled to the Han dynasty, where Emperor Wu gave him a princely title. A few months later Yudan died.

Life

The next year, 125 BC, the Xiongnu in 3 groups, each with 30,000 cavalry, again raided Chinese provinces. The Western Jükü-Prince, incensed that Chinese Court took away Ordos and built Shuofang (朔方城), a few times attacked the borders of China; and when entered the Ordos, plundered Shuofang, and killed and captured a multitude of officials and people.

In the spring of 124 BC, Wei Qing and four other generals led a force of 100,000, mostly light cavalry, against the Xiongnu. The Wise King (Tuqi) of the Right assumed they would turn back after he retreated, but they did not, and he was surprised at his camp. The Han emerged victorious, capturing ten petty chieftains, 15,000 Xiongnu, and one million livestock.

In the spring of 123 BC, Wei Qing and others led 100,000 cavalry against the Xiongnu, killing and capturing 3,000 north of Dingxiang. However Su Jian and Zhao Xin advanced too far with only 3,000 and were cut down. Zhao Xin defected while Su Jian managed to escape. Zhao Xin was originally a Xiongnu prince who had defected to the Han. He married one of Yizhixie's sisters and became his chief adviser on China. He convinced Yizhixie to move his capital further north of the Gobi Desert in order to avoid Han invasions and to lure them deeper into the steppes.

In 122 BC, a Xiongnu force of 10,000 raided Shanggu.

In the spring of 121 BC, Huo Qubing led a force of 10,000 cavalry and killed 8,960 Xiongnu west of the Yanzhi Mountains (in modern Gansu). In the summer he and several others marched west. Huo made it as far as the Qilian Mountains south of Jiuquan, killing and capturing 33,000 Xiongnu. The Xiongnu also invaded Yanmen Commandery so Li Guang and Zhang Qian gave chase. Li Guang was suddenly surrounded by 40,000 Xiongnu under the Wise King (Tuqi) of the Left but was able to hold off repeated attacks for two days until Zhang Qian arrived and the Xiongnu retreated. Zhang Qian was demoted to commoner status for arriving late.

In 120 BC, the Xiongnu raided Youbeiping and Dingxiang, carrying off 1,000 captives.

In the summer of 119 BC, Wei Qing and Huo Qubing led a large force of 100,000 cavalry, 200,000 infantry, and 140,000 supply horses against the Xiongnu. When the Han forces arrived, they found the Xiongnu already prepared and waiting and the Battle of Mobei commenced. Wei ensconced himself into a fortified ring of chariots and sent out 5,000 cavalry to probe the enemy. Yizhixie responded with 10,000 cavalry. The two sides skirmished until evening when a strong wind arose, at which point Wei committed most of his cavalry and encircled the Xiongnu. Yizhixie attempted to break out of the encirclement but lost control of his men and routed. Huo's forces advanced by another route and defeated the Wise King (Tuqi) of the Left. Li Guang failed to rendezvous on time and committed suicide. A hundred thousand horses were lost during the campaign, crippling Han cavalry forces for some time.

Yizhixie was angered by two serious defeats inflicted by Huo Qubing and ordered his commanders to report to court. Both Princes were scared of punishment, Prince Hunie wanted them to flee to China, but Prince Syuchu refused, so Hunie killed him. The treason of Hunie considerably tipped the balance of power in favor of the Han. In the Chinese raids between 124 and 119 BC, the Xiongnu lost, per Chinese annals, 300,000 killed or captured military and civilian people.Bichurin N.Ya., ''"Collection of information on peoples in Central Asia in ancient times"'', vol. 1, pp. 37–42

In 116 BC, the Xiongnu raided Liang Province.

In 114 BC, Yizhixie died and was succeeded by his son, Wuwei Chanyu.

His true name is debatable, as the three characters used to write it mean "this immature evil; this unnatural child".
