The term "Yangban" refers to the ruling class of the Joseon Dynasty in Korea, which lasted from 1392 to 1910. This elite group was composed of both civil and military officials who were educated in Confucian principles. The Yangban played a significant role in governance, culture, and society, often holding land and enjoying privileges that set them apart from commoners. Yangban status was typically hereditary, meaning it was passed down through families. They were expected to uphold moral standards and serve the state, but their influence declined in the late 19th century due to social changes and modernization efforts in Korea.
