The term "18왕조" refers to the 18 dynasties that ruled in Korea, primarily during the historical periods of the Three Kingdoms, Goryeo, and Joseon. Each dynasty contributed to the development of Korean culture, politics, and society, with significant achievements in art, literature, and governance. Among these dynasties, the Joseon Dynasty is particularly notable for its long reign from 1392 to 1910, during which Confucianism became the dominant ideology. The Goryeo Dynasty, preceding Joseon, is known for its advancements in ceramics and the establishment of the name "Korea."
