Jin Midi (134–86 BC) (, courtesy name Wengshu (翁叔), formally Marquess Jing of Du (秺敬侯), was a foreign prince and a warrior of the Western Han Dynasty. He was a Hu (胡) "barbarian" from a kingdom in central Gansu area and served as coregent early in the reign of Emperor Zhao of Han. Background Jin Midi was born in 134 BC to a Xiongnu allied royal family probably of Greco-Bactrian origins ruling central Gansu. He was the heir of the king Xiutu (休屠王; Soter/Σωτήρ), one of the major kings serving under the supreme ruler of the Xiongnu, Gunchen Chanyu. After Gunchen's death in 126 BC, his brother Yizhixie succeeded him. During this time, the king of Xiutu and another major king, the king Hunxie, were assigned for defending Xiongnu's southwestern border against the Han Dynasty – in modern central and western Gansu. In 121 BC, Emperor Wu of Han sent his general Huo Qubing to attack Xiongnu armies, dealing a great defeat on the Xiongnus and their Greco-Bactrian and Irano-Scythian allies in Gansu. In the campaign, Huo killed the kings Zhelan (折蘭王) and Luhu (盧胡王), as well as 8,000 Xiongnu and Hu (胡) allied horsemen warriors, while capturing the king of Xiutu's son, general, and a number of officials, as well as the golden statue (believed to be Buddha but also argued to be that of Zeus, and associated with the twelve chryselephantine statues captured a hundred years earlier in Gansu by Qinshi Huangdi) of king Xiutu to worship Heaven (祭天金人) Yizhixie Chanyu was greatly displeased, and was considering killing the kings Hunxie and Xiutu. The two kings, in fear, plotted to defect to the Han. When Emperor Wu sent Huo to accept their surrender, the king Xiutu changed his mind and tried to back out of defecting. The king Hunxie killed him and surrendered to the Han, along with the last Euthydemid Greco-Saka kingdom of Central Gansu area. Because the king of Xiutu was murdered, fourteen years old Midi (Demetrios), as well as his mother the queen, and his brother Leon (λέων), "Lun" (倫), were taken as exotic guests at the imperial palace. During Emperor Wu's reign On a later occasion, during an imperial feast, Emperor Wu ordered that horses be brought to him for him to examine. Midi, and a large number of fellow stable attendants, brought the horses, and as a number of Emperor Wu's beautiful concubines
