By what means did Zhou rulers keep control over all the different regions of their kingdom?

The Zhou rulers primarily kept control over the different regions of their kingdom through a combination of political alliances, military force, and administrative strategies.

1. Feudal System: The Zhou Dynasty implemented a feudal system, known as the "Fēngjiàn" system, where the king distributed territories to the nobles and enlisted their loyalty in return for their allegiance. The nobles were given the title of "Zūfù" and were responsible for governing and controlling their respective regions.

2. Mandate of Heaven: The Zhou rulers justified their authority through the concept of the "Mandate of Heaven," which stated that a ruler was appointed by the heavens to rule and maintain order. This belief served as a powerful ideological tool to legitimize their rule and maintain control over various regions by appealing to religious faith.

3. Administrative System: The Zhou rulers developed an efficient administrative system to govern the kingdom. They established a bureaucracy that managed and oversaw various aspects of governance. Officials were appointed to supervise and report on the affairs of different regions, ensuring that local rulers remained loyal to the central authority. This system helped the Zhou rulers to exert influence over the regions and maintain control.

4. Military Control: The Zhou rulers relied on military force to assert control over different regions. They had a standing army and used it to suppress rebellions and maintain order in areas that showed signs of defiance or resistance. The military might of the Zhou rulers acted as a deterrent, discouraging regions from challenging their authority.

5. Cultural Unity: The Zhou rulers promoted cultural unity and Chinese nationalism by establishing Confucianism as the ideology of the ruling class. This emphasis on shared values and principles helped in fostering a sense of loyalty among different regions by promoting a common culture and identity.

6. Diplomacy and Alliances: The Zhou rulers engaged in diplomatic efforts and formed alliances with regional leaders to ensure their loyalty. They often married off princesses to rulers of other regions, creating familial ties, and strengthening alliances. Through alliances and peaceful relationships, the Zhou rulers were able to maintain control over different regions without the need for military intervention.

It is important to note that as the Zhou Dynasty progressed, especially during the later stages of the Eastern Zhou period, the centralized control over various regions weakened. This decline in control eventually led to the fragmentation and disintegration of the dynasty, resulting in the period of Warring States.
