Choe U vs Li Wenzhong

Choe U succeeded his father Choe Chung-heon as head of the military regime, maintaining control over Goryeo through puppet kings. He continued the family's authoritarian rule, suppressing any opposition.

Choe U refused Mongol demands for submission and tribute, leading to a series of Mongol invasions. His defiance prolonged the war but ultimately resulted in devastating campaigns against Goryeo.

Choe U moved the Goryeo court to Ganghwa Island to escape Mongol attacks, using the island's natural defenses. This allowed the regime to continue resistance but left the mainland vulnerable to Mongol raids.

Choe U died, and his son Choe Hang succeeded him. However, internal divisions weakened the regime, leading to its eventual collapse in 1258 and the restoration of royal authority under Mongol influence.

Li Wenzhong, as a nephew and general of Zhu Yuanzhang, participated in the capture of Chuzhou and other key cities in the early Red Turban Rebellion. These victories helped establish Zhu's base in the Yangtze River region.

Li Wenzhong commanded a fleet that contributed to the decisive Ming victory over the rival rebel leader Chen Youliang at Lake Poyang. This battle eliminated Zhu Yuanzhang's main rival and paved the way for Ming unification.

Li Wenzhong was a key commander in the Ming army that captured Dadu, the Yuan capital, forcing Emperor Toghon Temur to flee. This event marked the formal establishment of the Ming dynasty over China.

Li Wenzhong led several military expeditions into Mongolia against the retreating Northern Yuan forces. He achieved victories at Yingchang and other locations, but failed to completely destroy the Mongol threat.
