What happened
The Han-Xiongnu wars ran on and off from 133 BCE to 89 CE, but their decisive phase came under Emperor Wu, who between 127 and 119 BCE sent generals Wei Qing and Huo Qubing against the Xiongnu with armies that, across the campaigns, numbered from 100,000 to over 300,000 men. The 119 BCE campaign pushed the Xiongnu north beyond the Gobi Desert and gave the Han control of the Hexi (Gansu) Corridor and the Ordos Plateau, the narrow, oasis-studded passage that connects China proper to the Tarim Basin and onward to Central Asia. Han sources record enormous costs alongside the victories: tens of thousands of Han casualties and, in one accounting, the loss of some 110,000 horses in a single set of campaigns, expenses that forced the government toward salt and iron monopolies and heavier taxation.
Why it matters
Holding the Gansu Corridor is what turned Zhang Qian's reconnaissance into a functioning road: Han garrisons, watchtowers, and the westward extension of the Great Wall secured the single overland passage merchants and envoys needed to move between China and everywhere west of it without paying whatever toll or price the Xiongnu chose to impose.
How we know
Han-era military and political history of the Xiongnu wars is recorded in the same narrative chronicles that describe Zhang Qian's mission, including sections on early Han relations with the Xiongnu translated and hosted by the University of Washington's Silk Road Seattle project.
