Đại Việt Quốc dân đảng (Vietnamese for Nationalist Party of Greater Vietnam), often known simply as Đại Việt, was a nationalist and anti-communist political party and militant organisation that was active in Vietnam in the 20th century. The party was founded by Trương Tử Anh,[1] known as Anh Cả Phương (Eldest Brother Phuong). Among the original members were several prominent figures in Vietnam's politics, such as Dr. Phan Huy Quat and Dr. Nguyen Ton Hoan.[2] During the era of French colonialism, the Dai Viet engaged in military attacks in an effort to gain independence. Some Dai Viet members were trained in Chinese military academies in Yunnan run by the Kuomintang, before the Communist revolution in China. The party was pro-Japanese during World War II, when the Japanese occupied Indochina. After the partition of Vietnam in 1954, the Dai Viet were banned in the communist North Vietnam. They continued to be active in South Vietnam as an opposition to President Ngo Dinh Diem, and were often implicated in coup plots against Diem, led by Dai Viet officers in the Army of the Republic of Vietnam.
