Jeong Cheol
Both Yi I and Jeong Cheol were forced to step down, while Sim Euigyeom stayed in court. Yi I returned in the early 1580s (Jeong Cheol also returned), and in 1582 declared himself a Westerner, revoking his earlier position as a neutral observer. However, the Westerners were no match for the Easterners, thus creating a solidly Easterner government in the 1580s until Jeong Yeorip's purge.
