The Vinh Lang stele from L礙 L廙ξ's mausoleum, erected in the 6th year of Thu廕要 Thi礙n reign (1433).

L礙 L廙ξ (1384 or 1385 ??1433), posthumously known with the temple name L礙 Th獺i T廙? was Emperor of Vietnam and founder of the Later L礙 Dynasty. L礙 L廙ξ is among the most famous figures from the medieval period of Vietnamese history and one of its greatest heroes.

Between 1418 and 1427 Le Loi fought the Ming Chinese occupation of Vietnam, ultimately defeating the Ming and re-establishing Vietnamese independence. He was also a diplomat, and having driven out the Chinese he formally established the L礙 Dynasty as the Ming Xuande Emperor officially recognized L礙 L廙ξ as the new ruler of Vietnam. In return, L礙 L廙ξ sent diplomatic messages to the Ming Court, promising Vietnam's loyalty as a vassal state of China and cooperation. The Ming accepted this arrangement, much as they accepted the vassal status of Korea under the Joseon Dynasty. The Chinese largely left Vietnam alone for the next 500 years, intervening only about once every hundred years.
