Jeong Do-jeon, also known by his art name Sambong (삼봉), was a prominent Korean scholar-official during the late Goryeo to the early Joseon periods. He served as the first Chief State Councillor of Joseon, from 1392 until 1398 when he was killed by the Joseon king Yi Bang-won. Jeong Dojeon was an adviser to the Joseon founder Yi Seong-gye and also the principal architect of the Joseon dynasty's policies, laying down the kingdom's ideological, institutional, and legal frameworks which would govern it for five centuries.

Yeonguijeong was a title created in 1400, during the Joseon and Korean Empire periods (1392–1910), and given to the Chief State Councillor as the highest government position of "Uijeongbu". Existing for over 500 years, the function was handed over in 1895 during the Gabo Reform to the newly formed position of the Prime Minister of Korea. Only one official at a time was appointed to the position and though was generally called Yeongsang, was also referred to as Sangsang, Sugyu or Wonbo. Although the title of Yeonguijeong was legally defined as the highest post in charge of all state affairs, its practical functions changed drastically depending on the particular King and whether that King's power was strong or weak.
