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.

Hwang Hui (1363–1452) was a politician of the Goryeo and Joseon dynasties, who came from the Jangsu Hwang clan and served as prime minister of the Joseon dynasty from 1431 to 1449.
