Li Cunxu vs Taejo of Joseon

Li Cunxu inherited the title Prince of Jin from his father Li Keyong. He continued the struggle against Later Liang, consolidating the Jin state as a major power in northern China.

Li Cunxu's Jin army defeated the Later Liang forces under Zhu Wen at Baixiang. This victory established Jin as the dominant military power in the north and marked a turning point in the war.

Li Cunxu led a successful campaign against Later Liang, capturing its capital Kaifeng and ending the dynasty. He then proclaimed himself emperor, founding the Later Tang dynasty.

Li Cunxu declared himself emperor of the Later Tang dynasty, claiming legitimacy as the restorer of the Tang lineage. He established his capital at Luoyang and reunified much of northern China.

Li Cunxu faced a mutiny by his own troops at Xingyuan during a campaign against the Khitans. He was killed in the fighting, leading to the collapse of Later Tang and the rise of Later Jin.

General Yi Seong-gye defeated a Japanese pirate (wokou) force at Hwangsan. This victory enhanced his military reputation and demonstrated his capability as a commander.

General Yi Seong-gye, ordered to invade the Ming dynasty's Liaodong region, turned his army back at Wihwado Island. This act of defiance against the Goryeo court led to a coup that eventually brought him to power.

Taejo implemented the Gwajeon Law, a land reform that redistributed land from the old Goryeo aristocracy to his supporters and the state. This weakened the old elite and strengthened the new Joseon ruling class.

Yi Seong-gye deposed the last Goryeo king and founded the Joseon dynasty, with its capital at Hanyang (modern Seoul). He established a new ruling class based on Confucian ideology, replacing the Buddhist-influenced Goryeo system.

Taejo of Joseon ordered the compilation of the Gyeongguk Daejeon, a comprehensive legal code that established the administrative and social structure of the Joseon dynasty. This code remained in effect for centuries.
