The name "Silk Road" originates from the lucrative trade in silk fabrics, primarily produced in China. Its origins trace back to approximately 114 BCE when the Han dynasty expanded into Central Asia, thereby stabilizing the previously turbulent region. Imperial envoy Zhang Qian embarked on exploratory missions beyond the territory to seek potential trading partners and establish diplomatic relations. These ventures spurred Chinese interest, leading to formalized diplomatic ties, commercial exchanges, and efforts to safeguard the routes through military presence and extensions of the Great Wall.
