趙光祖
Seonjo also reformed the civil service examination system, particularly the civil official qualification exam. The previous exam was mainly concerned with literature, not with politics or history. The king himself ordered the system to be reformed by increasing the importance of these other subjects. He also restored the reputations of executed scholars such as Jo Gwang-jo, who died in Third Literati Purge of 1519, and denounced the accomplishments of corrupt aristocrats, notably Nam Gon, who instigated the purge under Jungjong and contributed greatly to the corruption of the era. These acts earned the king the respect of the general populace, and the country enjoyed a brief era of peace.
