Queen Soheon (소헌왕후 심씨, 12 October 1395 – 19 April 1446), of the Cheongsong Sim clan, was a posthumous name bestowed to the wife and queen consort of Yi Do, King Sejong and the mother of Yi Hyang, King Munjong and Yi Yu, King Sejo. She was queen consort of Joseon and honoured as Queen Gong (공비) from 1418 until her death in 1446. Biography Early life Lady Sim was born as the first daughter and eldest child of nine children to Lord Sim On and Lady Ahn of the Sunheung Ahn clan. Her paternal uncle, Sim Jong, was King Taejo's son-in-law (titled Prince Consort Cheongwon) through his marriage to the king's daughter, Princess Gyeongseon. Marriage In 1408 at the age of 13, she was arranged to marry King Taejong's son, Prince Chungyeong, to which her title became Princess Gyeongsuk (경숙옹주, 敬淑翁主). It's said that she was chosen for the marriage due to the fact that King Taejong's older sister, Princess Gyeongseon, was her paternal aunt; thus having royal family connections. When her husband became grand prince, her title changed from ongju (옹주) to gongju (공주). Her parents were given royal titles: her mother was given "Internal Princess Consort Samhanguk of the Sunheung Ahn clan" (삼한국대부인 순흥 안씨), and her father was given "Internal Prince Cheongcheon" (청천부원군). During Taejong's 17th year of reign in 1417, Princess Gyeongsuk was also given the title of Internal Princess Consort Samhanguk (삼한국대부인, 三韓國大夫人). On 6 July 1418, during the 18th year of Taejong's reign, Princess Gyeongsuk became Crown Princess Gyeong (경빈, 敬嬪) when Grand Prince Chungyeong (later King Sejong) became the crown prince successor to the throne, and when her husband became king on 9 September 1418, her title changed to Queen Gong (공비, 恭妃; Gongbi meaning Courteous Consort). It's said that Queen Gong had a gentle and kind appearance but advocated strict adherence to laws and code of conduct. Royal political conflicts Just like her predecessor and mother-in-law, Queen Dowager Hudeok, Queen Gong experienced the loss of her family as Taejong felt threatened due to the influence of royal in-law's. She had lost her father, Sim On, in 1419 and two uncles in 1418 during her father-in-law's regency with her husband. Her mother and remaining relatives were also demoted to lower slave class. But in 1426, rather than having his in-law’s serve as slaves, Sejong expelled the Queen’s mother and relatives from Cheonan,
