Seongjong of Joseon

Seongjong (Korean: 성종; Hanja: 成宗; 28 August 1457 – 29 January 1495), personal name Yi Hyeol (이혈; 李娎), was the ninth monarch of the Joseon dynasty of Korea.

For the first time since Sejong the Great, Confucian scholars whose political views clashed with those of the conservative officials (members of the nobility who had helped Taejong and Sejo in their rise to power), were brought to court.

By appointing able administrators regardless of their political views, Seongjong made his rule more effective and his policies resulted in many positive innovations, increasing his number of supporters.

It was under Seongjong's reign that the "Widow Remarriage Ban" (1477) was enacted, which strengthened pre-existing social stigma against women who remarried by barring their sons from public office.

[4] In 1489, Yi Gu-ji, a woman from the royal clan, committed suicide at his order and was erased from family records, when it was discovered that she had cohabited with her slave after being widowed.

Led by General Heo Jong (허종; 許琮), the campaign was successful, and the defeated Jurchens commanded by Udige (兀狄哈) retreated to the north of Amrok River.
