Crown Prince Sado
Crown Prince Sado (Hangul: 사도세자; Hanja: 思悼世子) or Crown Prince Jangheon (Hangul: 장헌세자; Hanja: 莊獻世子), January 1735 - May 1762) was a Crown Prince of Joseon. He was the second son of King Yeongjo, and the father of King Jeongjo of Joseon.
After the death of his half brother Prince Hyojang, he became heir to the throne. Because of his mental illness and strange behaviour, his father had him locked in a rice chest and starved to death.
