The "고훈 시대" (Gohun Era) refers to a historical period in Korea characterized by significant cultural and political developments. This era is often associated with the rise of the Goryeo Dynasty, which ruled from 918 to 1392. During this time, advancements in art, literature, and technology flourished, contributing to the rich heritage of Korea. Additionally, the Gohun Era is marked by the establishment of the Confucian state ideology, which influenced governance and social structure. The period also saw the creation of the Korean script, known as Hangul, which played a crucial role in promoting literacy and education among the Korean people.
