During this period of the Shang dynasty, a lot of ideas evolved that affected Chinese history, for example, the idea of dynastic rule which lasted many years. The Shang also fought nomadic invaders with a well-organized army of peasants, nobles, and slaves. Nobles introduced a new invention, wheeled chariots, to China (Prentice/Pearson Hall pg: 328). Many religious ideas also came from this period, like the belief that heaven was the home of many gods and that Shang Di was the chief god (Prentice/Pearson Hall pg: 328). Also the belief that if you pleased the gods they would bring you good harvest, and if you didn't they would cause natural disasters.
