# bio (long form, separated for readability)
bio: |
  Born Yi Yu on 11 November 1417, the second son of Sejong the Great, he was never meant to rule. In 1453 he led a coup against his nephew King Danjong, then forced the boy's abdication two years later and took the throne as Sejo. The consolidation was brutal: he had his younger brothers Grand Prince Anpyeong and Grand Prince Geumseong killed along with other rivals. Once secure, he turned to statecraft — reformed the administration, revised land laws, campaigned against the Jurchens, promoted literature, and established court music. His Kyŏngguk Taejŏn became the foundational legal code of Joseon. He died on 2 October 1468, leaving a kingdom reshaped by violence and then by law.
