Huijong of Goryeo vs Michael III

King Huijong attempted to assassinate Choe Chung-heon by ambushing him during a palace visit. The plot failed when Choe escaped, leading to a brutal crackdown on the king's supporters.

After the failed coup, Choe Chung-heon deposed Huijong and exiled him to Ganghwa Island. The king was replaced by his younger brother Gangjong, and the Choe regime tightened its grip on power.

Huijong was exiled to Ganghwa Island, where he lived under house arrest until his death in 1237. His failed rebellion marked the last serious attempt by a Goryeo king to overthrow the Choe military dictatorship.

Michael III became Byzantine emperor at age two after the death of his father Theophilos. His mother Theodora served as regent. His reign saw the final restoration of icon veneration and a cultural revival.

Under the regency of Theodora, the Council of Constantinople in 843 formally restored the veneration of icons, ending the second iconoclast period. This event is celebrated as the 'Triumph of Orthodoxy' in the Eastern Orthodox Church.

Michael III sponsored the mission of Saints Cyril and Methodius to the Slavs. They created the Glagolitic alphabet and translated the Bible into Old Church Slavonic, spreading Christianity and literacy among the Slavic peoples.

Michael III was assassinated in his bedchamber by his co-emperor Basil I, who then became sole emperor. Michael's reign ended the Macedonian dynasty's rise. His death marked the beginning of the Macedonian Renaissance.
