Final answer:
The latter half of the Eastern Zhou dynasty is referred to as the Warring States period, lasting from 475 to 256 BCE, characterized by constant warfare among regional powers.
Step-by-step explanation:
The latter half of the Eastern Zhou dynasty is known as the Warring States period, which spans from 475 to 256 BCE. Following the prior era of relative stability and cultural development during the Spring and Autumn period, the Warring States period was marked by frequent and violent conflicts among regional powers. These states sought to expand their territories, absorb smaller kingdoms, and ultimately supplant the Zhou as the reigning sovereigns. This period was characterized by the decentralization of power and the rise of influential states like Chu, Qin, and Yan engaging in continuous warfare to assert dominance.
