Queen Sinjeong of the Hwangju Hwangbo clan[1] (Korean: 신정왕후 황보씨; Hanja: 神靜王后 皇甫氏; d. 19 August 983[a]) was the fourth wife of Taejo of Goryeo[2] who became the mother of Daejong of Goryeo and Queen Daemok.
The future Queen Sinjeong was born as the daughter of Hwangbo Je-gong, Duke Chungui (황보제공 충의공)[3] who was one of the Three Major Grand Masters (태위 삼중대광; 太尉 三重大匡) from Hwangju, North Hwanghae Province.
[citation needed] She married Wang Geon (왕건) as his second wife after he ascended the throne as the first King of Goryeo.
Since her only son and his wife died young, all of their children were raised by Queen Sinjeong and she devoted her entire affection to them.
[7] After her death on 19 August 983, she was promoted from a Royal consort's position into Queen Mother Sinjeong (신정왕태후; 神靜王太后)[8] and was buried in Sureung tomb; she also received a posthumous name.
