이이
In 1584 Yi I died, only months after being recalled to court. Seeing Yi's death as a chance, the Easterner Yi Bal attacked Sim Euigyeom and many of the Westerners. Jeong Cheol, Seong Hon, and Sim were fired, creating a solidly Easterner government for five years until 1589. Yi I and Seong Hon were ferociously attacked by Easterners, often on the charges that they had attempted to create a faction. This was often refuted by the pupils of Yi and Seong, however they could not effectively oppose the Easterners.
