Sent by Emperor Wu of Han to seek an alliance with the Yuezhi, Zhang Qian travelled west from Chang’an, survived long captivity by the Xiongnu, reached Central Asia, and returned with new information about lands and exchange networks beyond Han territory.
The mission did not create the routes and societies it encountered, but it materially expanded Han knowledge and diplomacy across Central Asia. It helped establish the long-distance connections later known as the Silk Roads.
