See it on the World Religions map →What it is
Yi Seong-gye founded Joseon (조선) in 1392 with scholar-officials who blamed Buddhism for the previous Goryeo dynasty's decline. Monasteries lost land, and Buddhism retreated to the mountains. State exams (gwageo) tested Zhu Xi's commentaries. Scholars such as Yi Hwang (Toegye) and Yi I (Yulgok) debated li and qi at a high level. Ancestor rites (jesa), eldest-son inheritance and strict roles for women spread from the elite to commoners by the 1700s. Joseon lasted until 1897, when it was renamed the Korean Empire.
Why it matters
It shaped Korean family life still visible today: jesa ancestor rites, respect for elders and education, and clan genealogy books. Its orthodoxy also drove the persecution of Korea's early Catholics.
Sources and history
The Annals of the Joseon Dynasty (Joseon Wangjo Sillok), a detailed court record; the law code Gyeongguk Daejeon; scholars' collected works; and surviving Confucian academies (seowon), nine on UNESCO's list.
Questions and debates
Historians debate whether Joseon Confucianism stifled trade and change or gave Korea 500 years of stable, literate government; views of its effect on women's lives also differ.

▸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.
▸Joseon Korea's Confucian state persecuted Korean Catholic martyrsHistorical record
The connection
Joseon's Neo-Confucian order rested on ancestral rites and loyalty to king and family. When Catholics stopped performing those rites, which their church ruled idolatrous, they seemed to attack the state itself. Court factions also used anti-Catholic purges against rivals. The result was waves of arrests and executions from 1791 to 1866.
When and where
Across Joseon Korea, especially around Seoul and in Chungcheong and Jeolla provinces; persecutions of 1791, 1801, 1839, 1846 and 1866, the last under the regent Heungseon Daewongun.
Historical evidence
Joseon royal annals and interrogation records list charges and executions; Catholic accounts and French missionaries' letters describe the same events.
Questions and debates
Historians weigh how much the purges were about faith versus factional politics, as in 1801, when a rival faction targeted Southerner (Namin) officials with Catholic ties.
