The Zhou Dynasty ruled China after overthrowing the Shang Dynasty in 1046 BCE, believing they had the Mandate of Heaven to rule. The dynasty went through three periods, starting with the Western Zhou Period until internal conflicts weakened royal control. This led to the Spring and Autumn Period where nobles rebelled, and finally the Warring States Period where the nobles fought each other for power. The document instructs students to learn about the Mandate of Heaven concept and its role in justifying royal authority through textbook readings and worksheet activities.
