King Jeongjo

King Jeongjo (28 October 1752 – 18 August 1800) was the 22nd ruler of the Joseon Dynasty of Korea. He made various attempts to reform and improve the nation of Joseon. He was preceded by his grandfather King Yeongjo (1724–1776) and succeeded by his son King Sunjo (r. 1800–1834). He is widely regarded as one of the most successful and visionary rulers of Joseon along with King Sejong.

Early life
He was the son of Crown Prince Sado, who was put to death by his own father, King Yeongjo. His mother, Lady Hyegyeong, wrote an autobiography, The Memoirs of Lady Hyegyeong (한중록, 閑中錄), detailing her life as the ill-fated Crown Princess of Korea. This collection of memoirs serves as a significant source of historical information on the political happenings during the reigns of King Yeongjo, King Jeongjo and King Sunjo.
When he was the Crown Prince, King Jeongjo met Hong Guk-yeong (홍국영, 洪國榮), a controversial politician who first strongly supported Jeongjo's accession and toiled to improve the king's power, but ended up being expelled because of his desire for power.
Jeongjo spent much of his reign trying to clear his father's name. He also moved the court to the city of Suwon to be closer to his father's grave. He built Hwaseong Fortress to guard the tomb. It is now a UNESCO World Heritage Site.

Accession
His era was quite in disorder as his father was killed by royal decree of his own father, King Jeongjo's grandfather. King Yeongjo's ultimate decision to execute Prince Sado was greatly influenced by other politicians who were against Prince Sado. After King Yeongjo's death and on the day that he became the King of Joseon, he sat on his throne in the throne room and looked at everyone and said, "I am the son of the late Crown Prince Sado..." A bold statement that sent shivers to all the politicians who were complicit in his father's death. During his accession, he also ordered a royal decree that his mother, Lady Hye Gyeong, be a Dowager Queen since his father, her husband, was supposed to be the King before him but never occurred as it should have. She thus became the Queen Dowager, the widow of Crown Prince Sado. From then on, King Jeongjo went through many turbulent timeperiods but overcame them with the aid of Hong Guk-yeong.

Renaissance
King Jeongjo led the new renaissance of the Joseon dynasty. It was initially stopped by continuing the policy of Yeongjo's Tangpyeong rule. He tried to control the politics of the whole nation to advance and further national progress.
He made various reforms throughout his reign, notably establishing Kyujanggak (규장각), a royal library. However, its purpose was to improve the cultural and political stance of Joseon and to recruit gifted officers to run the nation. He also spearheaded bold new social initiatives, opening government positions to those who were barred because of their social status.
Jeongjo had the support of the many Silhak scholars including Jeong Yak-yong, Yu Deuk-gong, Pak Ji-won and Pak Je-ga, and in addition the Silhak scholars supported Jeongjo's regal power. King Jeongjo's reign also saw the further growth and development of Joseon's popular culture.

Death
He was known to history as an innovative person, in spite of his high political status in Joseon. He died suddenly at the age of 48 in 1800 under mysterious circumstances, without seeing his lifelong wishes realized by his son, Sunjo. There are many books regarding the mysterious death of Jeongjo, even today.
He is buried with his wife at the royal tomb of Geolleung (건릉, 健陵) in the city of Hwaseong.
