李滉
During forty years of public life he served four kings (Jungjong, Injong, Myeongjong and Seonjo). On his death, Yi Hwang was posthumously promoted to the highest ministerial rank, and his mortuary tablet housed in a Confucian shrine as well as in the shrine of King Seonjo. His disciples and followers reorganized the "Dosan seodang" to Dosan Seowon in 1574.
