The Eastern Zhou (/dʒoʊ/; c. 770–256 BC) is a period in Chinese history comprising the latter half of the Zhou dynasty, following the Western Zhou era and the royal court's relocation eastward from Fenghao to Chengzhou (near present-day Luoyang). The Eastern Zhou was characterised by the weakened authority of the Ji family, the Zhou royal house. It is subdivided into two parts: the Spring and Autumn period (c. 770 – c. 481 or 476 BC), during which the ancient aristocracy still held power in a large number of separate polities, and the Warring States period (c. 481 or 476 – 221 BC), which saw the consolidation of territory and escalation of interstate warfare and administrative sophistication.

Eastern Zhou period in the context of Sun Tzu
Sun Tzu (/suːn ˈdzuː, suːn ˈsuː/;traditional Chinese: 孫子; simplified Chinese: 孙子; pinyin: Sūnzǐ) was a Chinese military general, strategist, philosopher, and writer who lived during the Eastern Zhou period (771–256 BC). Sun Tzu is traditionally credited as the author of The Art of War, a Classical Chinese text on military strategy from the Warring States period, though the earliest parts of the work probably date to at least a century after him.
Sun Tzu is revered in Chinese and East Asian culture as a legendary historical and military figure; however, his historical existence is uncertain. The Han dynasty historian Sima Qian and other traditional Chinese historians placed him as a minister to King Helü of Wu and dated his lifetime to 544–496 BC. The name Sun Tzu—by which he is more popularly known—is an honorific which means "Master Sun". His birth name was said to be Sun Wu (traditional Chinese: 孫武; simplified Chinese: 孙武) and he is posthumously known by his courtesy name Changqing (Chinese: 長卿). Traditional accounts state that the general's descendant Sun Bin wrote a treatise on military tactics, also titled The Art of War. Since both Sun Wu and Sun Bin were referred to as "Sun Tzu" in classical Chinese texts, some historians thought them identical, prior to the rediscovery of Sun Bin's treatise in 1972.
