Queen Sundeok

Queen Sundeok of the Gyeongwon Yi clan (15 April 1094 – 21 September 1118 ) or formally called as Queen Mother Mungyeong, was a Korean Goryeo queen consort as the second wife of Yejong of Goryeo and the mother of his successor, Injong of Goryeo.

Early life
The future Queen Sundeok was born on 15 April 1094 as the second daughter of Yi Cha-gyŏm and Lady Ch'oe, the second daughter of Choe Sa-chu from the Haeju Choe clan. She had six brothers, one older sister, and two younger sisters. Since King Munjong's reign, the Gyeongwon Yi clan was already produced many queen consorts or wives for the Goryeo royal family, so it can said that she came from a noble family.

Marriage and Palace life
She firstly entered the palace in 1108 (3rd year reign of Yejong of Goryeo) at 15 years old and was given the royal title as Princess Yeondeok and was put to live in Yeondeok Palace. One year later, she gave birth to their first son, Wang Hae (the future King Injong) and when learning that the baby was a boy, the King sent an envoy to issue a decree and expressed his joy by giving her silverware, silk , horses , wood and grain  while putting up a token  to pay their respects on her.

In 1114, she formally became his queen consort. It was said after his first wife died, he was very sad and after marrying Lady Yi, he loved and favored her very much due to her docile, intelligent, wise, soft and gentle character. Her mother, Lady Ch'oe, was formally called as "Grand Lady of the Joseon State". While her grandmother, Lady Kim was formally called as "Grand Lady of the Tongui State".

According to Chaebongmun after entering the palace, she set an example of marital harmony, never made a private request and gave birth to a son for generations to come. She was also praised for her virtues as she took care of her husband by advising him to wake up when a rooster crows. While she was bedridden, Yejong, who was grieve-stricken, brought out medicine and food himself for the queen. However, she died at the age of 24 on 21 September 1118 due to her own illness, which caused Yejong to wept many times and even heard the admonition from her servants that he was too polite.

Besides Prince Wang Hae, they also had 2 daughters (Princess Seungdeok and Princess Heunggyeong).

Later life
Yejong personally enshrined and went out to Sinbong Gate to see her funeral procession in Sureung Tomb (수릉,  綏陵) even though the officials told him not to do that.

For in memory of her, the King was said to prepared a private room to enshrined her portrait at Anhwa Temple    and always visited between February and August in the following year, while also visiting their Wedding Hall several times. The king went there again to bow down, to which the officials strongly discouraged him, but he chose to go against them and said, "조제의 예식은 송나라 임금도 한 적 있다. 나는 그 일을 본받은 것 뿐이다! 그리고 혼당 한번 간다고 무슨 큰일이 나는가?"
 * "The memorial ceremonies were even held by the Song Dynasty's ruler. I just imitated it! Also, what's going to happen if I go to the wedding hall once?"

While also saying that he did what he wanted to do.

In 1120, after finishing the mourning of the queen, Yejong summoned the Crown Prince, his father-in-law and land governor Yi Cha-ryang to be comforted and to gave him goods.

After her husband's death in 1146, their only son, Wang Hae ascended the throne and married her younger sisters, which made two of them become her sisters and daughter in-laws at the same time. Their brothers were all occupied one place at the time of Injong's reign. However, after their father, Yi Cha-gyŏm's deposition and exiled, her two younger sisters were deposed from their position too as a result.

After her death, she was posthumously honoured as Queen Sundeok and Grand Queen Mother Mungyeong  after her only son ascended the throne in 1122. In her father's record on Goryeosa, she was called as an "Empress consort".
 * In 1140, name Ja-jeong was added to her posthumous name.

Benefits for Gyeongwon Yi clan
Queen Sundeok, a woman born into the highest aristocratic family of that time, was chosen to become the Queen consort and Mother of the nation. She gave birth to a son who later ascended the throne and received a lot love and affection from her husband, which can be said that she lived a faithful life to the virtues demanded of her time. But, their marriage greatly enhanced the authority of Yi Cha-gyŏm and the King's favor towards her also became the source of interest and power for Yi who later tried to rebel.
