Officially established in 59 or 60 BCE, Protector-General was the highest military position in the west during its existence. During its peak in 51 BCE, the Wusun nation was brought under submission. After at least 18 different protector generals, of whose names only 10 of their names are known, the post was abandoned, by the time of Wang Mang's Xin dynasty in 23 CE.
