State Councilor
The Lesser Yun faction continued to attack their opposition. In 1546, Yun Won-hyeong impeached his older brother, Yun Won-ro, who was executed a few days later along with his followers. Facing no opposition from the government, Yun Won-hyeong became Minister of Personnel 이조판서 in 1548, Left State Councilor in 1551 and ultimately Chief State Councilor 영의정 in 1563.
