I am at the great wall of china currently so I might as well tell you the story of the ZHOU dynasty
The ZHOU dynasty started by taking over the shang dynasty and taking their place
We made many things such as the Mandate of heaven it was the idea that a ruler must be just to keep the approval of the gods.
Also we had a system called fuedilism wich was also known as the feudal system, was the combination of the legal, economic, military, and cultural customs that flourished in Medieval Europe
Feudalism was used In In ancient china to and not just Medieval Europe
But then the ZHOU Dynasty fell as the the implementation of the fengjian system
