Wei noble executed after Sima Yi coup.
Xiahou Xuan was appointed Minister of the Guards, a key position controlling the imperial guard. This role gave him influence over palace security. He was a respected scholar and official, known for his integrity and opposition to corruption.
Following Sima Yi's coup, Xiahou Xuan was demoted and exiled to Lelang Commandery in modern Korea. This removal from central power was part of Sima Yi's purge of Cao Shuang's faction. Xiahou Xuan remained in exile until his execution.
Xiahou Xuan was executed by Sima Shi, son of Sima Yi, on charges of plotting rebellion. He was implicated in a conspiracy to overthrow the Sima clan. His death marked the elimination of a prominent Cao family loyalist and further consolidated Sima control.
