Princess Jeongsin of the Gaeseong Wang clan (; 1236 — 4 May 1319[1]), firstly called as Princess Jeonghwa or also known as Primary Consort Jeonghwa, was a Goryeo royal family member as the granddaughter of Duke Yangyang who became the first wife of her third cousin once removed, King Chungnyeol and also the aunt of King Chungseon's 3rd wife.
The future Princess Jeonghwa was born in 1236 as part of the Gaeseong Wang royal family as the daughter of Wang In, Duke Sian who was the grandson of King Sinjong through his second son, Duke Yangyang. She had two brothers; one of which would become the father of Chungseon's consort.
In 1260, during the first year reign of King Wonjong of Goryeo, she married Crown Prince Wang Sim and became his princess consort .[2] [3] In 1274, Wang Sim married Kublai Khan's daughter, Qutugh Kelmysh as his new queen consort, which meant Lady Wang couldn't become the queen even though she was his principal wife when he was crown prince.[4] She was then demoted into a lower rank, but was still honoured as Princess Jeonghwa and lived in the "Jeonghwa Palace" .[5]
She was said to have had a bad relationship with Qutugh Kelmysh and was hated so much by the latter that she was forced to live in a separate palace so she couldn't come close to the king. In 1275, a banquet was held to celebrate the birth of the new queen's first son. When Chungnyeol gave an order to place Princess Jeonghwa and Qutugh Kelmysh in the same position, Qutugh Kelmysh became very angry, believing that she was being treated as an equal of his first wife. She then suddenly moved Jeonghwa's seat. After a while, Princess Jeonghwa knelt down and offered a glass of wine to her, but the King turned around and blinked and the banquet ended immediately.[6]
A year later in 1276 (2nd year reign of King Chungnyeol), a maid said that Princess Jeonghwa had a shaman curse Qutugh Kelmysh and 43 people, including Duke Jean, planning to do something unpleasant and trying to enter Ganghwa-do.[7] Princess Jeonghwa was then imprisoned in Najang, but with the help of official Yu-Gyeong, she was able to defend herself and be released along with the others who were involved.[8]
In 1284, there was an incident where Jeonghwa misunderstood the common people and made them servants, which made them file a lawsuit, called Apryangsageon since the judgment was made in favor of her under King Chungnyeol's order.[9] However, the presiding judge Gim Seo of this case, died suddenly after appearing on the scene the day after the verdict and only Yi Haeng-geom who was aware of the injustice of the case, survived.
Princess Jeonghwa was believed to be devout in Buddhism and often prayed in Jeondeung Temple . There is also a record that she asked a Buddhist monk In Gi to print the Tripitaka Koreana and kept it in Jeondeung temple.[10] When she was the primary wife in the past, she was also known as Primary Consort Jeonghwa .
After Princess Jeguk's death, King Chungnyeol abdicated the throne to his legitimate son in 1298, Princess Jeonghwa's title was changed into Princess Jeongsin alongside Chungnyeol who was able to came back to the palace.[11] After this, she and the retired king lived together in Sangsu Palace and King Chungseon also held a ceremony for them. She then passed away on 4 May 1319[12] and was buried in the same year.[13]
She bore Chungnyeol a son[14] and 2 daughters.[15] Although her only son, Duke Gangyang was the oldest son of the king, he couldn't ascend the throne since his younger half brother, Chungseon of Goryeo was the legitimate son. Meanwhile, Gangyang's second son, Wang Go, was favoured by Chungseon so her brother, Marquess Seowon's daughter became one of Chungseon's consorts.[16]
