In 1392 General Yi Seong-gye founded the Joseon dynasty and made Zhu Xi's Neo-Confucianism the state's official philosophy.

Yi Seong-gye overthrew the Goryeo dynasty, whose rich Buddhist establishment was blamed by reformers for corruption and land grabbing. His chief strategist, Jeong Do-jeon, designed the new state of Joseon (조선) on Confucian models and attacked Buddhism in his Critique of Buddhism (1398). Temples lost land and slaves; officials were chosen by exams on the Confucian classics read through Zhu Xi; and Zhu Xi's Family Rituals became the model for ancestral rites, though adoption took two centuries. Hanyang, now Seoul, became the capital.
Why it matters
Joseon lasted over 500 years, arguably the most thoroughly Confucian state in history, and its values of ancestor rites, education and hierarchy still shape Korean family life.
Where it comes from
The Annals of the Joseon Dynasty, a day-by-day court record on UNESCO's Memory of the World register, plus Jeong Do-jeon's surviving writings and the dynasty's law codes.
Still debated
Historians debate how far the founding was driven by Confucian ideals versus an elite power struggle, and how quickly ordinary Koreans actually gave up Buddhist practices.

▸Zhu Xi and the Four Books became the ideology of Joseon Korea founded on Neo-Confucian linesWell documented
The connection
Korean reformers saw Zhu Xi's teaching as a blueprint for remaking a state they considered corrupted by Buddhist wealth and aristocratic privilege. Joseon's founders used it to justify the new dynasty, design institutions, reform landholding, and require Confucian rituals from the royal court down to family ancestral rites.
When and how
Zhu Xi's works reached Korea around 1290 with the scholar An Hyang; by 1392 officials like Jeong Do-jeon and Gwon Geun used them to shape the new state.
How we know
Jeong Do-jeon's state plans and anti-Buddhist essays cite Zhu Xi directly, and Joseon exam rules prescribed his commentaries.
Debates and open questions
Historians debate whether Zhu Xi's teaching drove the founding or mainly legitimized a seizure of power by Yi Seong-gye and his allies.
▸Joseon Korea founded on Neo-Confucian lines set the stage for Yi Hwang (Toegye)Mostly agreed
The connection
A century and a half of state-sponsored Neo-Confucianism produced schools, exams and a scholar class steeped in Zhu Xi. But bloody purges of scholar-officials between 1498 and 1545 made many, including Toegye, wary of court life and drawn to private study and teaching, the setting in which his reflective philosophy grew.
When and how
Joseon Korea, 1392–1550s; Toegye passed the civil service exam in 1534 and served under several kings while repeatedly retiring to Andong.
How sure are we?
Toegye's letters and resignations record his reluctance to serve; the Annals document the purges, including the death of his elder brother Yi Hae in 1550.
Debates and open questions
Historians debate how much the purges, versus personal temperament, explain the inward, self-cultivating turn of Joseon Neo-Confucianism.
