Princess Myeongan

Princess Myeongan (30 June 1665 – 25 June 1687), personal name Yi On-hui, was a Korean princess as the third daughter of Hyeonjong of Joseon and Queen Myeongseong.

Biography
On December 21, 1671 (12th year of her father's reign), Yi On-hui was honoured as Princess Myeongan.

In 1679 (5th year of Sukjong's reign), she married Oh Tae-ju, a son of Oh Du-in , who was a key figure of the Seoin faction. Her husband was honoured as Prince Consort Haechang and their formal wedding ceremony was held on December 18, 1680.

The drought being severe at that time, Song Si-yeol and others filed an appeal requesting that the Princess's residence be built in a modest way to reduce the size and cost.

One year later, after the Princess's in-laws illegally occupied the mounds and fields in Deoksan, Chungcheong Province, a lawsuit broke out and the King ordered them to return the land.

Princess Myeongan died on June 25, 1687, five days from her birthday at the age of 21 years old, and is buried in Sasa-dong, Ansan, Gyeonggi Province, South Korea.
