Sunjo of Joseon

Sunjo ascended to the throne at age 10 in 1800 upon the death of his father, King Jeongjo.

In 1802, King Sunjo married Lady Kim of Andong, known posthumously as Queen Sunwon, daughter of Kim Jo-sun who was a leader of Andong Kim clan.

Since he ascended the throne at a young age, Queen Dowager Jeongsun, the second queen of King Yeongjo, ruled as queen regent, which allowed her to wield power over state affairs. Despite King Sunjo's efforts to reform politics, the fundamental principles of government deteriorated. The state examination became disordered and corruption in the government personnel administration prevailed. This resulted in disorder in society and various riots broke out among the people, including the revolt by Hong Gyeong-nae in 1811–1812. The Ogajaktongbeop (五家作統法), a census registration system to group five houses as one unit, was carried out in this period, and oppression against Roman Catholicism began in earnest.[1]

King Sunjo died after reigning for 35 years in 1834 at the age of 44. He was first buried next to Jangneung, Paju, the tomb of King Injo and Queen Inyeo but later moved to Illeung, Seoul as the Feng Shui at the old site was deemed to be unfavourable.[2]
