14. Political Unity and Territorial Expansion
The Han Dynasty (206 BCE-220 CE) solidified the concept of a unified Chinese empire by integrating various peoples and regions. Under Emperor Wu (141-87 BCE), the Han expanded their territory significantly, establishing commanderies in the Hexi Corridor and Inner Mongolia, and extending the Great Wall to protect these new borders. This expansion laid the foundation for China’s enduring vision of national unity and territorial integrity. (britannica.com)
