Which empire controlled the largest area between the shang zhou qin and han empires?

The Han Dynasty controlled the largest area among the Shang, Zhou, Qin, and Han empires. At its peak, the Han Dynasty expanded China's territory significantly, reaching regions that included parts of modern-day Korea, Vietnam, and Central Asia. The Han's extensive trade networks, including the Silk Road, further solidified its influence and territorial reach. In contrast, the Shang and Zhou dynasties had more limited territorial control compared to the expansive reach of the Han.
