The Eastern Zhou is a period in Chinese history comprising the latter half of the Zhou dynasty from c. 771 BCE to 256 BCE, following the Zhou capital's relocation eastward to Chengzhou, near present-day Luoyang. The Eastern Zhou was characterised by the weakened authority of the Zhou royal house, it is subdivided into two parts: the Spring and Autumn period, during which the ancient aristocracy still held power in a large number of separate polities, and the Warring States period, which saw the consolidation of territory and escalation of interstate warfare and administrative sophistication.
