Confucius (Kong Fuzi, 'Master Kong') was born in the state of Lu, in present-day Shandong, to a minor aristocratic family. He grew up learned but poor, served in bureaucratic posts, and travelled the realm in his middle years hoping to advise rulers on virtuous governance — few listened. His real influence came after his death, through students whose recollections were compiled as the Analects (Lunyu).

His teaching is practical rather than metaphysical. Its central concepts: ren (humaneness, care for others), li (ritual propriety, social form), xiao (filial responsibility), and junzi (the exemplary person). A good society, for Confucius, arises not from law alone but from well-cultivated individuals forming the right relationships. The ruler is no exception — from king to farmer, everyone is called to moral growth.

From the Han dynasty (2nd century BCE) onward, Confucian thought became the backbone of state ideology, shaping education, the imperial examination system, family life, and statecraft across China, Korea, Japan, and Vietnam for two millennia. In the 20th century revolutionary movements targeted Confucianism as a relic of the old order; today it is once again read across East Asia as a cultural reference point.
