Crown Prince Sado

Korean prince

Prince Sado of Joseon or Prince Jang Heon of Joseon (Hangul: 사도세자 or 장헌세자, 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.
