Confucius (Kong Qiu/Kongzi) is born in Qufu in the state of Lu during the Eastern Zhou’s Spring and Autumn period, the political setting that shaped his later ethical and governmental thought.
Zisi (Kong Ji), Confucius’s grandson, becomes a key figure in the early intellectual genealogy of Confucianism, traditionally credited with helping transmit the tradition that later connects to Mencius.
Confucius dies in Lu. His teachings continue through students and later followers, forming the core of an emerging Confucian tradition in the late Spring and Autumn / early Warring States context.
Zisi dies (traditional dates place him in the early Warring States period). Early Confucian circles continue to develop debates about virtue, ritual, and rulership across competing states.
The Doctrine of the Mean (Zhongyong), later embedded in the Liji and traditionally attributed to Zisi, is commonly dated in its textual core to the late Zhou / Warring States era, reflecting early Confucian concerns with moral self-cultivation and harmonious order.
Scholarly consensus places substantial composition of the Analects (Lunyu) in the Warring States period, with later stabilization/redaction continuing into the Han—making it a key textual bridge from Confucius’s circle to later Confucianism.
Mencius (Mengzi) is born in Zou. Later tradition places him within a lineage connected to Zisi’s teaching circle, and he becomes a major builder of early Confucian moral and political philosophy.
In debates with rulers and rival thinkers during the Warring States era, Mencius advances the influential Confucian claim that humans have inborn moral “sprouts,” shaping later Confucian ethics and statecraft arguments.
The Jixia Academy in Qi is credited (in many reconstructions) with an early 4th-century BCE foundation and develops into an important center where diverse schools—including Confucians such as Xunzi (per later accounts)—compete and cross-fertilize ideas.
The text known as the Mencius—an anthology of conversations and anecdotes attributed to Mencius—circulates as a key vehicle for early Confucian political and moral argumentation.
Xunzi (Xun Kuang) is born (approximate date). He later becomes a major Confucian synthesizer and critic, writing systematic arguments about ritual, learning, and governance during late Warring States debates.
Mencius dies (traditional date). His ideas remain central to later Confucian self-understanding, especially in debates over moral psychology and the responsibilities of rulers.
After years of teaching and disputation, Xunzi takes office in Chu as magistrate of a small district (reported as 255 BCE in one common account), illustrating the practical, statecraft-oriented turn in late Warring States Confucianism.
Han Feizi, later famed as a leading Legalist theorist, is reported to have studied under the Confucian philosopher Xunzi—evidence of how Confucian teaching circles intersected with rival political philosophies in the 3rd century BCE.
Sources summarized in modern scholarship indicate Xunzi was still alive when his patron Lord Chunshen was assassinated (238 BCE), placing Xunzi’s mature activity very late in the Warring States period.
Xunzi dies (approximate date; ancient sources disagree). His work Xunzi becomes a major classical repository of arguments for ritual and education, and influences later debates in both Confucian and non-Confucian political thought.
In the late 2nd to early 1st century BCE, Sima Qian writes the Shiji (Records of the Grand Historian), including a foundational biography of Confucius that powerfully shapes later historical memory of Confucius and early Confucian figures.
