Since its foundation, the Joseon Dynasty, which had succeeded to the state apparatus of the Goryeo Dynasty (918 – 1392), had been adjusting its government organization. In 1400, the second year after King Jeongjong came to the throne, he renamed the Dopyeonguisasa (都評議事司; Privy Council[4]), the highest organ in charge of the state affairs of Goryeo, to Uijeongbu and created the post of Jwauijeong along with that of Uuijeong (Third State Councillor[5]). The three officials were collectively referred to as the Samjeongseung (Three top officials[6]) or the Samuijeong (Three High Councilors).[3]
