Choe Chung-heon vs Li Tingzhi

Choe Chung-heon led a military coup, killing rival generals and seizing control of the Goryeo government. He established a military dictatorship, reducing the king to a figurehead and ruling through puppet monarchs.

Choe Chung-heon created a private military government, the 'Choe family regime,' which controlled Goryeo for four generations. He appointed loyal generals to key posts and sidelined the civil bureaucracy.

Choe Chung-heon purged hundreds of civil officials and scholars who opposed his rule, executing or exiling them. This solidified military dominance over the traditional aristocracy and silenced dissent.

Choe Chung-heon led Goryeo forces in repelling initial Mongol incursions into the Korean peninsula. His military preparations delayed Mongol conquest, though the kingdom eventually became a vassal.

Li Tingzhi commanded the defense of Yangzhou, a key city in the Southern Song, against the invading Mongol army under Kublai Khan. Despite being outnumbered and lacking reinforcements, he held the city for over a year. His stubborn resistance delayed the Mongol advance and became a symbol of Song loyalty.

After Yangzhou was betrayed and fell to the Mongols, Li Tingzhi was captured. He refused to surrender and was executed by the Mongol forces. His death, along with his steadfast defense, made him a martyr for the Song cause and a figure of loyalty in Chinese history.
