Han dynasty expansion opens the ancient Silk Road network
The Silk Road took shape around 114 B.C.E., when Han envoy Zhang Qian’s missions into Central Asia helped stitch together overland routes stretching more than 6,400 km. Almost no one traveled its full length; goods passed hand to hand through oasis towns, carried largely by Sogdian merchants. It remains one of history’s great experiments in connection across distance.
