Even before the first Chinese dynasty, complex societies inhabiting the area now known as China, organized into settlements. The most important settlements were protected by rammed earth walls. The first dynasty, the Shang (1600-1050 BCE), built large walls as early as around 1,550 BCE. Differing from later walls, which were built along a strategic defense line, these walls were built to enclose the settlements and areas.

The Shang would eventually be conquered from the west by the Zhou Dynasty (1046-256 BCE), which developed a complex system of government. In fact, it was the Zhou system’s decline that Confucius (551-479 BCE) witnessed and drew from greatly for his political philosophy. The Zhou also created walled cities, and it was at this time that the first major conflicts with northern tribesman, the Xianyun, were recorded.
