Prince Nà Ângch'ang (; 16 July 1599 â 17 November 1615), formally known as Grand Prince Nà Ângch'ang (), and with the personal name Yi Jeon (), was a Korean royal prince of the Joseon dynasty. He was the third son of Wonjong of Joseon and Queen Inheon of the Neungseong Gu clan. He was also the second younger brother of Injo of Joseon. Prince Nà Ângch'ang was noted for his proficiency in equestrianism, martial arts, and particularly in archery.
The future Grand Prince NÃ Ângch'ang was born on 16 July 1599 (the 32nd year of Seonjo of Joseon's reign) in Saemun-ri, Seongseo, Hanseong-bu, Joseon. He was the youngest son of Prince Jeongwon () and Princess Consort Yeonju of the Neungseong Gu clan (), the daughter of Gu Sa-maeng ().
Although he was the biological son of Prince Jeongwon, he was later adopted by his second uncle, Prince Sinseong (), who had no heirs. He was raised by his adoptive mother, Princess Consort Sin (), the daughter of Sin Rip (). As a result, Sin Rip became his maternal grandfather, and Sin Gyeong-jin () and Sin Gyeong-hui () were regarded as his maternal uncles.
From a young age, Prince NÃ Ângch'ang was described as intelligent, talented, and of good appearance. He enjoyed reading and was nicknamed Hyeongongja (, meaning "virtuous young master"). In 1601, at the age of three, he was granted the title Master NÃ Ângch'ang (). In 1612, at the age of fourteen, he was elevated to the title Prince NÃ Ângch'ang ().
During the reign of his half-uncle, Gwanghaegun of Joseon, rumours circulated that Prince Nà Ângch'ang harboured ambitions for the throne and posed a threat to Gwanghaegun's rule. In 1608, following GwanghaegunâÂÂs ascension to the throne and the death of Yu Yeong-gyeong () in prison, Prince Nà Ângch'ang was granted the title of Jeongunwonjong gongsin, rank 1 (). Later, in 1613 (the fifth year of Gwanghaegun's reign), after Prince Imhae () was imprisoned, he was awarded the title of Iksawonjong gongsin, rank 1 ().
On 14 August 1615, there was speculation that Gwanghaegun intended to elevate him to the title of Grand Prince NÃ Ângch'ang (). However, on 22 August 1615, Gwanghaegun ordered his arrest. After questioning him at Injeongmun (), the prince was imprisoned and subsequently exiled to Gyodong-do, Ganghwa.
On 17 November 1615 (the eighth year of Gwanghaegun of Joseon's reign), Prince NÃ Ângch'ang took his own life after writing a farewell letter to his parents, which he entrusted to his brother-in-law at a government office. However, the susaeng () who received the letter was unable to deliver it immediately and instead concealed it in his sash, later burying it in the ground. In March 1623, following the rebellion and subsequent accession of his eldest brother, Grand Prince Neungyang (), the letter was finally delivered to him.
According to other records, on 19 November 1615 (the seventh year of Gwanghaegun's reign), Gwanghaegun exiled Prince NÃ Ângch'ang to Gyodong Island on charges of treason, where he was reportedly executed shortly after his arrival. Upon hearing of his death, their father, Wonjong, was said to have been overcome with grief. He fell ill and, after consuming alcohol while unwell, died on 2 February 1619 (the eleventh year of Gwanghaegun's reign) at the age of 40.
On 13 March 1623, Prince NÃ Ângch'ang's eldest brother, Prince Neungyang (), led a coup that deposed Gwanghaegun and ascended the throne. During Injo's reign, Prince NÃ Ângch'ang, along with Gim Je-nam (), Grand Prince Yeongchang (), and Yi Tae-gyeong, Prince Jilleung (), was posthumously reinstated.
Prince Nà Ângch'ang was initially honoured with the posthumous title of Gadeokdaebu (). On 15 October 1629 (the seventh year of InjoâÂÂs reign), he was further elevated to Hyeollokdaebu ().
In 1630, after his parents were posthumously granted the titles of Grand Internal Prince () and Grand Internal Princess Consort (), Prince NÃ Ângch'ang was elevated to the status of Grand Prince () on 4 May 1632 (the tenth year of Injo's reign). His tombstone was subsequently inscribed with the title Grand Prince NÃ Ângch'ang ().
Prince NÃ Ângch'ang died on 17 November 1615, not long after his marriage to Lady Gu, the future Princess Consort Gu (), in March 1615. Although she did not bear any children, he had one daughter with a concubine, Princess Yi Yeong-on (), who later married HÃ Â SÃ Â (), the third younger brother of HÃ Â Mok.
He was initially buried in Gunjang-ri, Geumchon-myeon, Yangju-gun, Gyeonggi Province (later part of Geumgok-ri (Geumgok-dong, Namyangju), Migeum-myeon). On 29 October 1629, during the sixth year of Injo of Joseon's reign, his tomb was relocated to Nanji-won, Geuncheohyeok-dong, Namhansanseong Fortress, Godae-myeon, Gwangju-gun, Gyeonggi Province. It was later moved again to the mountain behind Gogol Gungan Village, Chungung-ri, Dongbu-myeon, Gwangju-gun, Gyeonggi Province.
On 13 May 1658, his adopted son, Grand Prince Inpyeong (), died and was buried on 13 July of the same year beside NÃ Ângch'ang's tomb. However, after 35 years, his remains were moved to Pocheon, Gyeonggi Province. To the left of NÃ Ângch'ang's tomb are the tombs of Yi Hyeok, Prince Uiwon () and his wife, while the tombs of Yi Yeon-Eung () and his wife are located below them.
Meanwhile, NÃ Ângch'ang's residence was confiscated by Gwanghaegun of Joseon and incorporated into Gyeongdeok Palace (). After his death, in March 1623, his elder brother Prince Neungyang () led a rebellion and ascended the throne as King Injo. NÃ Ângch'ang was posthumously reinstated on 15 March that same year and was initially honoured with the title Gadeokdaebu (), later changed to Hyeollokdaebu (). King Injo designated his third son, Grand Prince Inpyeong (), as NÃ Ângch'ang's adoptive heir.
