King Wonseong
38th king of Silla (Kim Gyeong-sin), who created the Dokseo Sampumgwa to select officials by their reading of the Confucian classics
He helped Kim Yang-sang (King Seondeok) crush Kim Ji-jeong’s revolt in 780. When Seondeok died in 785 the nobles chose Kim Ju-won, but heavy rain is said to have kept Kim Ju-won from crossing the Al River, and Kim Gyeong-sin took the throne instead. In 788 he created the Dokseo Sampumgwa to select officials by their mastery of texts such as the Zuo Commentary, the Book of Rites, the Analects and the Classic of Filial Piety, but opposition from true-bone nobles and the bone-rank system kept it from working well, though it did help spread Confucian learning. Kim Ju-won’s son Kim Heon-chang later cited this succession as the grievance behind his rebellion.
