Grand Prince à ¬ian (; 1382 â 26 August 1398), birth name Yi Pangsà Âk (), was a Korean crown prince. Born of Queen Sindeok, he was the eighth and youngest son of Taejo of Joseon and the first crown prince of Joseon.
Grand Prince à ¬ian was appointed as the first crown prince of the Joseon Dynasty in 1392, but was subsequently deposed following the first strife of princes. He was exiled and was later assassinated in October 1398 at a young age. He was later given the posthumous title Sodo ().
He was the second son of Goryeo General Yi Song-gye and his second wife, Queen Sindeok, and the younger brother of Prince Muan. Yi Song-gye had two wives, both of whom were his legal wives. In July 1392, Yi Song-gye founded the Joseon Dynasty and became its first king.
He was elected crown prince on 7 September 1392 in the first year of King Taejo's reign. In this way, he overcame his older brothers. Later, Yi Pangwà Ân and others claimed that Chà Âng Tojà Ân and his supporters chose him as crown prince. No evidence confirms that Yi Pangsà Âk was elected crown prince by Chà Âng Tojà Ân.
During his reign as crown prince, his wife Hyeonbin Ryu and eunuch Yi Man (ì´ë§Â, æÂÂè¬) committed adultery, which resulted in punishment for both. Hyeonbin Ryu was deposed and banished from the palace whereas Yi Man was beheaded in 1393. Hyeonbin Shim was chosen as the crown prince's new wife in 1397.
On 15 September 1396, the crown prince's mother, Queen Sindeok, died.
On 6 October 1398, the First Strife of Princes began under the leadership of Prince Jeongan Yi Bang Won. The crown prince personally led the army against Prince Jeongan's forces stationed in front of Gwanghwamun Gate, but he refused to confront the rebels after officer Bong Won-ryang (ë´ÂìÂÂëÂÂ, å¥Âå Âè¯) reported, âÂÂFrom Gwanghwamun to Namsan, the elite cavalry is fully equipped".
After killing enemies such as Chà Âng Tojà Ân, Nam à ¬n (ë¨ìÂÂ, Ã¥ÂÂ誾; 1382âÂÂ1398), Shim Hyosaeng (ì¬Ã¨ìÂÂ, æ²ÂÃ¥ÂÂçÂÂ; 1348âÂÂ1398), and Park Wi (ë°ÂìÂÂ, æ´è³; ?-1398), Prince Jeongan chose Yi Panggwa, Prince Yeongan, his older brother, as crown prince.
The deposed Crown Prince Yi Bang Seok, who was to be exiled, was later sent from Gyeongbokgung Palace through the Yeongchumun Gate. With the approval of the Dopyeonguisasa assembly, Prince Jeongan's supporters, including Yi Geo-yi (ì´거ì´, æÂÂå± æÂÂ; 1348âÂÂ1412), commissioned assassins to assassinate the deposed crown prince. He was then known as Deposed Crown Prince Yi Bang-seok (ÃÂÂì¸ì ì´방ìÂÂ, 廢ä¸Âå æÂÂè³碩), but was posthumously just titled as Sodo (ìÂÂëÂÂ, æÂÂæ¼).
His body was buried in Gwangju, Gyeonggi Province, and he was given the title of Duke Ohwon (ì¤ìÂÂê³µäºÂÃ¥ÂÂå ¬).àOn 14 September 1406, King Taejong gave Yi Bang-seok the posthumous title of Prince Sodo (ìÂÂëÂÂêµ°, æÂÂæ¼åÂÂ) or Duke Sodo (ìÂÂëÂÂê³µ), and gave Yi Bang-beon the posthumous title of Prince Gongsun (ê³µìÂÂêµ°, æÂÂé ÂÃ¥ÂÂ) or Duke Gongsun (ê³µìÂÂê³µ).ÃÂ
274 years later on 21 August 1680, King Sukjong granted Yi Bang-seok the posthumous title of Grand Prince à ¬ian (ìÂÂìÂÂëÂÂêµ°, å®Âå®Â大åÂÂ) and Bang-beon the title of Grand Prince Muan (무ìÂÂëÂÂêµ°, æ«å®Â大åÂÂ).
His tomb is located in the city of Gwangju at the Grand Prince Uian Cemetery. On 13 April 1998, his mausoleum was designated as a historical heritage site of Gyeonggi Province and registered with number 166.
