Princess Deokon

Princess Deokon (1822–1844 ) was the youngest daughter of Sunjo of Joseon and Queen Sunwon of the Andong Kim clan. She was the last Princess of Korea born to a King and Queen.

Biography
The Princess was born in 1822 as the youngest daughter of Sunjo of Joseon and Queen Sunwon of the Andong Kim clan. On 6 March 1829, at the age 8 years old, she was granted the title of Princess Deokon.

Her father passed away on 13 December 1834, when she was 12 years old.

Three years later, on August 13, 1837 (during the reign of her nephew, Heonjong of Joseon), she married Yun Ui-seon, son of Yun Chi-seung (1790–?). Her husband was later honoured as Prince Consort Namnyeong.

Princess Deokon died 7 years after her marriage, on 1844, when she was around 21 to 22 years old. It was said that she lost her life two hours after giving birth to a daughter, who also died soon after. Meanwhile, her husband, Yun Ui-seon, died in 1887 around the age of 64 to 65 during the 24th year of Emperor Gojong's reign.

The Princess' clothes and belongings were added to South Korea's Intangible Cultural Heritage, which were kept by Yun Yong-gu's daughter, Yun Baek-yeong, and it is known that in the 1960s they were collected by Seok Ju-seon. Her Memorial Museum at Dankook University keeps 228 objects which belonged to the Princess and her descendants, in an exhibition called "The Last Princess of Joseon, The Relics of Princess Deokon" ('조선의 마지막 공주, 덕온가(家)의 유물전').
