Sadae

Sadae is a Korean term which is used in pre-modern contexts. Sadae is a Confucian concept, based on filial piety, that describes a reciprocal hierarchical relationship between a senior and a junior, such as a tributary relationship. The term is used as a descriptive label for bilateral foreign relations between Imperial China and Joseon dynasty Korea. Korea's sadae toward China was first employed by Silla in the 7th century, but it was not fully implemented until the Confucianization of Korea in the early Joseon dynasty. Korea's sadae toward China from the 7th century to the 13th century was only nominal.
