Seolleung / Royal Tomb of Queen Jeonghyeon

Queen Jeonghyeon, of the Papyeong Yun clan, was a posthumous name bestowed to the wife and third queen consort of Yi Hyeol, King Seongjong and the mother of Yi Yeok, King Jungjong. She was queen consort of Joseon from 1479 until her husband's death in 1495, after she was then honoured as Queen Dowager Jasun during the reigns of her adoptive son, King Yeonsan from 1495 to 1506, and her son, King Jungjong from 1506 to 1530.

Queen Jeonghyeon came to wield considerable power and also influence a number of political decisions which secured her son's position on the throne, however, her excessive reliance on her kin and paternal clan paved way for the occurrence of the second and third literati purges.
