Final answer:
The Zhou Dynasty's Mandate of Heaven justified the overthrow of unjust or unwise leaders, establishing an important principle in Chinese monarchical history.
Step-by-step explanation:
The Zhou Dynasty, in Chinese history, developed the concept of Mandate of Heaven. The Mandate of Heaven justified the overthrow of leaders that were seen as unjust or unwise. In this concept, a ruler was believed to have the approval and blessing of the heavens as long as they ruled justly and wisely. However, if they failed to do so, it was taken as a sign that they had lost the Mandate of Heaven, and thereby their right to rule, which could be seized by others. This principle was a significant factor in the political stability and continuous cycle of rulers in China's monarchical history.
