Uà Âijà Âng (), also known as the Right State Councilor, was the Third State Councillor of the Uijeongbu (State Council) during the Joseon period of Korea (1392âÂÂ1897). The Uà Âijà Âng was variously referred to as Usang, Ujà Ângsà Âng, Ugyu, Uhap, or Udae.
Uà Âijà Âng was the lowest of the three prime ministers, ranked senior first (jeong-il-pum; ), roughly equal to the Second Deputy Prime Minister in modern day.
The position was created in 1400 by Taejong, replacing the former position Munha Usijung () during Goryeo period. Its name was changed to Uà Âijà Ângbusa () in 1418, then to à ¬ijà Ângbu Uà Âijà Âng () in 1455.
During the Joseon dynasty, Uà Âijà Âng was also granted posthumously as an honorable position to fathers-in-law of Grand Internal Princes (), Grand Princes (), or Crown Princes' sons ().
The position was abolished in 1894.
