Nguyễn Trãi (阮廌), also known under his style name Ức Trai (抑齋); (1380–1442) was an illustrious Vietnamese Confucian scholar, a noted poet, a skilled politician and a master tactician. He was at times attributed with being capable of almost miraculous or mythical deeds in his designated capacity as a close friend and principal advisor of Lê Lợi, Vietnam's hero-king, who fought to free the country from Chinese rule. He is credited with writing the important political statements of Lê Lợi and inspiring the Vietnamese populace to support open rebellion against the Ming Dynasty rulers. He is also the author of "Great Proclamation upon the Pacification of the Wu" (Binh Ngo Dai Cao).
