Biography.
Lady Kwon was born on 17 April 1418 into the Andong Kwon clan to Kwon Jeon and his second wife, Lady Choi of the Haeju Choi clan. She had a younger brother.
At the age of 12-13, Lady Kwon entered the palace in 1431 alongside two other women, Lady Jang and Lady Hong. All were granted the 4th rank of "seunghwi" consort (). She gave birth to a daughter in either 1432 or 1433, but she died before she reached one year old.
In 1435, Consort Kwon became pregnant, which drew the jealously of the crown princess, who had no children and feared that she would be removed in favour of Kwon. She gave birth to Princess Gyeonghye in 1436. After Crown Princess Sun was banished for sleeping with her maid, officials suggested that Kwon be made the next crown princess, as she already had a child, was older than Lady Hong, and her father's government position was high. She was made Royal Noble Consort Kwon late in 1436.
On 9 August 1441, Royal Noble Consort Kwon gave birth to a son named Yi Hong-wi, which was much celebrated, as he was the crown prince's only son. However, Kwon did not recover from the birth and died a day later. She was granted the posthumous title of Royal Noble Consort Hyeondeok () and buried at Sorung () in Ansan, Gyeonggi.
Posthumous status.
When Munjong of Joseon ascended the throne, he granted Kwon the title of Queen Hyeondeok. Her son bestowed a full posthumous name on her during his reign.
In 1457, several years after Sejo of Joseon had deposed her son as king, Queen Hyeondeok's brother and his mother-in-law were found guilty of treason and executed. Both the queen and her father were posthumously demoted to commoner status. Her status was later restored and her remains were moved to Hyeonreung to be buried alongside Munjong of Joseon.
