See it on the Korean History map →What happened
The Jiphyeonjeon (집현전) existed earlier mostly in name, but in 1420 Sejong made it a working academy inside the palace. Ten to twenty of the best young exam graduates were spared routine duties to research Chinese precedents, draft policy and tutor the crown prince; some got paid study leave (sagadokseo). They compiled histories, ritual, medical and farming works, and the Hangul commentary. After several members plotted in 1456 to restore the deposed boy-king Danjong, King Sejo abolished it.
Why it matters
It made scholarship a direct tool of government and produced much of Sejong's work; members executed for loyalty to Danjong became Korea's model of principled officials.
Think of it like
Like an in-house research and policy staff that reports straight to the owner, not to the operating managers.
How we know
The Sillok list its members, duties and projects; its scholars are named in the postface of the 1446 Hunminjeongeum Haerye.

The connection
Hall of Worthies scholars, including Jeong In-ji, Seong Sam-mun and Sin Suk-ju, wrote the Haerye's explanations and examples and researched Chinese sound systems, even consulting an exiled Ming scholar in Liaodong. Whether they helped design the letters, or mainly explained and spread them, is the open question.
When and how
1443–1446 in Hanyang (Seoul); eight scholars led by Jeong In-ji wrote the Haerye; Sin Suk-ju and Seong Sam-mun made research trips to Liaodong.
How sure are we?
Their names appear in the Haerye's postface. But the annals credit the king alone, and the Hall's deputy head, Choe Man-ri, opposed the letters.
Debates and open questions
Older textbooks credited the Hall jointly; many scholars now see Sejong as designer and the Hall as editors and promoters. Opinions still differ.
▸King Sejong the Great established Hall of Worthies (Jiphyeonjeon)Well documented
The connection
In 1420 Sejong turned the Jiphyeonjeon, until then mostly an honorary title, into a working academy in the palace. He chose young exam winners, gave them books, study leave and direct access to him, and used their research to draft policy, histories, rituals and practical manuals.
When and how
1420 in Gyeongbokgung, Hanyang (Seoul); expanded through the 1420s–1430s with scholars such as Jeong In-ji, Sin Suk-ju and Seong Sam-mun.
How we know
The Sejong sillok record its reorganization, staffing and many book projects.
Debates and open questions
How much policy truly came from the Hall, rather than from the king and senior ministers, is hard to separate in the records.
