Joseon Dynasty Founded in Korea

In 1392, the general Yi Seonggye took the throne of the Korean kingdom of Goryeo and soon began a new dynasty called Joseon. The state he founded lasted until 1910, making it one of the longest-ruling dynasties in East Asian history. Joseon shaped Korea's political institutions, social hierarchy, language policy, and cultural identity, and its legacy remains visible in modern Korea. (The event is listed under China in some databases, but it took place on the Korean peninsula and the Joseon kingdom was an independent state, though it was a tributary partner of Ming China.)

By the late fourteenth century, Goryeo, which had ruled since 918, was badly weakened. It had endured decades of Mongol domination under the Yuan dynasty, followed by the Yuan's collapse, along with Japanese pirate raids on the coasts and rivalry among powerful aristocratic families. Many officials, especially a rising group of Neo-Confucian scholars, believed that corruption and concentrated landholding were impoverishing farmers and the state. Yi Seonggye had risen to prominence as a military commander who defeated pirates and Red Turban raiders.

The decisive moment came in 1388. Yi was ordered to lead an army north against Ming forces in Liaodong, but he turned back at the Wihwa Island on the Yalu River and marched on the capital, seizing control of the court. Over the next four years he and his allies, notably the scholar-official Jeong Dojeon, carried out land reform and sidelined opponents. Yi was formally enthroned in 1392, and the new name Joseon, recalling an ancient Korean kingdom, was adopted in 1393 with Ming approval. In 1394 the capital moved to Hanyang, today's Seoul.

The new rulers promoted Neo-Confucianism as the foundation of government and social life. Civil service examinations, a scholar-official class known as the yangban, and ritual practices emphasizing family hierarchy and ancestor veneration became central to society. Buddhism, which had enjoyed state favor under Goryeo, lost official support and was often restricted, though it survived among the population. Historians note that the actual social impact varied over time, and Confucian norms spread more deeply into everyday life in later centuries than in the early years.

Joseon's early period produced notable achievements. King Sejong, who reigned from 1418 to 1450, sponsored scientific work and the creation of the Korean alphabet, hangul, promulgated in the 1440s. The dynasty later endured major invasions by Japan in the 1590s and by the Manchus in the 1620s and 1630s, and it gradually became inward-looking. Foreign pressure in the nineteenth century eventually led to Japanese domination, and the dynasty ended with Japan's annexation of Korea in 1910.
