Danjong, born Yi Hong-wi, was the sixth king of the Joseon Dynasty in Korea, ascending to the throne in 1452 at the age of 12 following the death of his father, King Munjong. His reign, however, was short-lived and tumultuous, largely due to his young age and the political intrigue that surrounded his rule. Upon his accession, the actual governance fell to Chief State Councillor Hwangbo In and Left State Councillor General Kim Jong-seo. However, this government was overthrown in a coup d'état in 1453 by Danjong's uncle, Grand Prince Suyang, who later became King Sejo. The coup resulted in the deaths of Hwangbo In and Kim Jong-seo.

The political tension escalated in 1456 when six court officials plotted to restore Danjong to the throne. The plot was foiled, and the conspirators were executed. Subsequently, Danjong was demoted to Prince Nosan and exiled to Yeongwol, while his wife lost her queen dowager status. Initially, Sejo showed reluctance to execute Danjong, but as he perceived his nephew as a persistent threat, he ultimately ordered Danjong's death in 1457. Danjong's tragic end marked a significant moment of political ruthlessness in the Joseon Dynasty.
