Lê Lợi
Lê Lợi formally re-established Đại Việt as the Xuande Emperor of the Ming Empire officially recognized Lê Lợi as the king of Dai Viet in 1431. In return, Lê Lợi sent diplomatic messages to the Ming imperial court, promising his loyalty as a nominate tributary state of China and cooperation, and paid 50,000 gold taels for obtaining investiture. The Ming imperial court accepted this arrangement, much as they accepted the vassal status of Korea under the Joseon dynasty. Lê Lợi briefly established good relations with Champa’s king, Indravarman VI (r. 1400–1441).
