Crown Prince Sado
The era before his rule was 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 Crown Prince Sado was greatly influenced by other politicians who were against the Crown Prince. After King Yeongjo's death and on the day that Jeongjo 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..." This was a bold statement that sent shivers down the spines of all the politicians who were complicit in his father's death.
