Three Families dominate the state of Lu

562 BC - 481 BC

Death of Duke Huan of Qi leads to succession chaos

643 BC

King Helü of Wu seizes the throne

514 BC

Prince Guang had King Liao of Wu assassinated by Zhuan Zhu, who hid a dagger inside a fish, and took the throne as King Helü. With Wu Zixu and Sun Tzu as advisors, he built Wu into a formidable military power aimed at dominating the southeast and striking at Chu.

Goujian becomes King of Yue

496 BC

Goujian ascended the throne of the southern state of Yue and soon clashed with neighboring Wu. After being crushingly defeated and forced into humiliating servitude in Wu, he endured years of hardship—legend says tasting gall daily to remember his humiliation—before plotting his revenge.

Han, Zhao, and Wei formally recognized as states

403 BC

King Weilie of Zhou formally granted the titles of marquis to the leaders of Han, Zhao, and Wei, legitimizing their partition of Jin. Many historians take this recognition as the official end of the Spring and Autumn period and the beginning of the Warring States period.

Philosophy and Culture

Laozi traditionally composes the Tao Te Ching

571 BC

According to tradition, the sage Li Er, called Laozi, wrote the Tao Te Ching before vanishing westward through the Hangu Pass. This short poetic work of Daoist philosophy, teaching harmony with the natural Way and wu wei (non-action), became foundational to Chinese thought alongside Confucianism.

Confucius dies in Lu
