Guy of Lusignan vs King Yeonsangun of Joseon

Guy of Lusignan led the Crusader army to a disastrous defeat at the Battle of Hattin against Saladin. The army was surrounded and destroyed, leading to the capture of Guy and the fall of Jerusalem.

Following the Battle of Hattin, Saladin captured Jerusalem in October 1187. Guy's defeat directly led to the loss of the city, which had been under Christian control since 1099.

Guy was released from captivity by Saladin in 1188. He was allowed to return to the Crusader states, but his reputation was ruined, and he was unable to regain his former authority.

Guy of Lusignan led the siege of Acre, which began in 1189. The siege lasted two years and involved the forces of the Third Crusade. Guy's role was overshadowed by the arrival of Richard the Lionheart and Philip Augustus.

After the Third Crusade, Guy purchased the island of Cyprus from the Knights Templar. He became the first Lusignan ruler of Cyprus, establishing a dynasty that lasted until 1489.

Yeonsangun ordered the execution and exile of many scholar-officials from the Sarim faction, accusing them of criticizing his rule. This purge intensified factional conflict and established his reputation for tyranny.

Yeonsangun launched a second, more brutal purge, executing hundreds of officials and their families. He targeted those involved in his mother's death and anyone who opposed his excesses, further destabilizing the court.

Yeonsangun abolished the Office of Special Counselors (Hongmungwan) and other advisory bodies, centralizing power in his own hands. This act removed checks on royal authority and allowed his tyranny to go unchecked.

A group of officials and military leaders staged a coup, deposing Yeonsangun and exiling him to Ganghwa Island. He was the first Joseon king to be forcibly removed from power, and his half-brother Jungjong was installed as king.
