Biography
The future Queen Anhye was born as the first daughter of Huijong of Goryeo and Queen Seongpyeong. She later married her second cousin, Gojong of Goryeo and changed her clan into Yu. Her mother-in-law, Queen Wondeok was initially her aunt and the daughter of Princess Changrak who also changed her clan to Yu.In 1211, she was honoured as Princess Seungbok not long after her marriage with Gojong and lived in "Seungbok Palace". She then formally became a Queen Consort following her husband's ascension to the throne in 1218. They had two daughters and two sons.
She died on June 1, 1232 and her husband wore mourning clothes for three days and grieved over her death. The then-military ruler Ch'oe U gave her a coffin made of gold and silver. At the time she died, her parents were still alive and were said to be sad when they heard the news.
After her death, Gojong didn't remarry again, so it was presumed that they had a good relationship both as cousins and spouse. She then received her posthumous name and honoured as Queen Mother after their oldest son ascended the throne as King Wonjong in 1260.
