See it on the World Religions map →What it is
Thinkers of the Song dynasty (960–1279) wanted Confucianism to answer the deep questions Buddhism and Daoism had claimed. Zhu Xi (1130–1200) taught that everything combines li, the underlying pattern or principle, and qi, material energy. Human nature is good in principle; study and moral effort clear away clouded qi. His commentaries on the Four Books were the basis of China's civil-service exams from 1313 until 1905. Wang Yangming (1472–1529) later stressed the mind's innate moral knowledge instead.
Why it matters
For centuries it was state orthodoxy in China and Korea and highly influential in Tokugawa Japan, shaping exams, family ritual, government and social hierarchy across East Asia.
Sources and history
Zhu Xi's commentaries and recorded conversations (Zhuzi yulei); imperial exam records; Korean and Japanese editions and state curricula; private academies such as White Deer Grotto, which Zhu Xi revived.
Questions and debates
How much it borrowed from Buddhism, which its thinkers openly opposed, is debated; so is whether it is better called a philosophy or a religion.

▸Neo-Confucianism (Zhu Xi) revived ConfucianismHistorical record
The connection
Neo-Confucians saw themselves not as innovators but as restorers of the true teaching of Confucius and Mencius, which they said had been lost for over a thousand years. Zhu Xi grouped the Analects, Mencius, the Great Learning and the Doctrine of the Mean as the Four Books, and his commentaries became the standard way to read Confucius.
When and where
Song China, 11th–12th centuries; Zhou Dunyi, the brothers Cheng Hao and Cheng Yi, and Zhu Xi, who published his Four Books commentaries in 1190.
Historical evidence
Zhu Xi's commentaries and their use in imperial exams from 1313; Neo-Confucians' own writings claiming the 'transmission of the Way' (daotong).
Questions and debates
Scholars debate how faithful Neo-Confucianism was to early Confucianism, or whether its metaphysics made it essentially a new system.
▸Neo-Confucianism (Zhu Xi) responded to Chan, Seon and Zen BuddhismMostly agreed by scholars
The connection
Many Song thinkers studied Chan (Zen) Buddhism in their youth, then rejected it as a selfish withdrawal from family and society. Yet they took up its questions and methods: quiet-sitting meditation, an inward search for one's true nature, and the idea of a single principle running through all things, which echoes Buddhist teaching.
When and where
Song China, 11th–12th centuries, when Chan monasteries thrived; Zhu Xi himself studied Chan before turning to Confucian learning.
How do we know?
Zhu Xi's writings both criticize Buddhism and describe his early Chan interest; similar terms and practices appear in both traditions.
Questions and debates
How much Neo-Confucianism borrowed from Buddhism, rather than developing older Chinese ideas, is a long-running debate; its founders denied any debt.
▸Joseon Korea's Confucian state adopted Neo-Confucianism (Zhu Xi)Historical record
The connection
Joseon's founders, guided by the scholar Jeong Do-jeon, made Zhu Xi's Neo-Confucianism the state ideology, displacing Buddhism. Korean scholars studied Zhu Xi so closely that Joseon became arguably more orthodox than China; openly challenging Zhu Xi could end a career. The 'Four-Seven Debate' between Toegye and Gi Daeseung (1559–66) added original Korean ideas.
When and where
Korea from 1392; Neo-Confucian learning had arrived from Yuan China around 1290 with the scholar An Hyang.
Historical evidence
Joseon law codes, exam curricula and court annals; the surviving writings of Jeong Do-jeon, Toegye and Yulgok.
Questions and debates
Historians debate how quickly Confucian norms reached ordinary Koreans, and whether strict orthodoxy closed Joseon to new ideas such as Western learning.
▸Donghak and Cheondogyo blended teachings of Neo-Confucianism (Zhu Xi)Mostly agreed by scholars
The connection
Choe Je-u was educated as a Confucian scholar, and Donghak kept Neo-Confucian ideals: moral self-cultivation, sincerity, reverence and harmony between heaven and humanity. He blended these with Buddhist and Daoist elements but made them radically egalitarian: if heaven dwells in every person, peasants and women deserve the respect Joseon reserved for elites.
When and where
Gyeongju, 1860s; Choe Je-u wrote one scripture in classical Chinese for scholars and another in Korean verse for less educated followers.
How do we know?
Donghak scriptures use Confucian terms such as sincerity (seong) and reverence (gyeong); Cheondogyo describes its teaching as uniting Confucianism, Buddhism and Daoism.
Questions and debates
Scholars debate whether Donghak was at heart a Confucian reform or a break with Confucianism, given its equality teaching and challenge to Joseon's class order.
