In 1392, General Yi Seonggye led a successful coup to take political power in Korea from U of Goryeo. Seonggye's followers forced him to take the crown as Taejo of Joseon, thus establishing a new dynasty. In search of a justification for its rule given the lack of a royal bloodline, the new regime received recognition from China and integration into the Imperial Chinese tributary system within the context of the Mandate of Heaven. Within this tributary system, China assumed the role of a "big brother", with Korea maintaining the highest position among the tributary states, which also included countries such as the Ryukyu Kingdom, Lan Xang, Đại Việt, the Ayutthaya Kingdom, in return for accepting the subservient tributary role of a "younger brother".
