The Spring and Autumn period in Chinese history lasted approximately from 770 to 481 BCE which corresponds roughly to the first half of the Eastern Zhou period. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius. During this period, royal control over the various local polities eroded as regional lords increasingly exercised political autonomy, negotiating their own alliances, waging wars amongst themselves, up to defying the king's court in Luoyi. The gradual Partition of Jin, one of the most powerful states, is generally considered to mark the end of the Spring and Autumn period and the beginning of the Warring States period.

The Spring and Autumn Annals is an ancient Chinese chronicle that has been one of the core Chinese classics since ancient times. The Annals is the official chronicle of the State of Lu, and covers a 241-year period from 722 to 481 BC. It is the earliest surviving Chinese historical text to be arranged in annals form. Because it was traditionally regarded as having been compiled by Confucius—after a claim to this effect by Mencius—it was included as one of the Five Classics of Chinese literature.
