How did the power of the king change during the zhou dynasty?

The Zhou Dynasty (1046-256 BCE) was the longest-lasting of China’s dynasties. It followed the Shang Dynasty (c. 1600-1046 BCE) and it finished when the army of the state of Qin captured the city of Chengzhou in 256 BCE. The long history of the Zhou Dynasty is normally divided in two different periods: Western Zhou (1046-771 BCE) and Eastern Zhou (770-256 BCE), so called following the move of the Zhou capital eastwards where it was safer from invasion.

The most influential minds in the Chinese intellectual tradition flourished under the Zhou, particularly towards the last period of the Zhou Dynasty, considered a time of intellectual and artistic awakening. Many of the ideas developed by figures like Laozi, Confucius, Mencius and Mozi, who all lived during the Eastern Zhou period, would shape the character of Chinese civilization up to the present day.
