Professor Nguyen Quoc Tri, born in 1929, is the 3rd descendant of Nguyen Van Tuong. Trained at Binh Son Primary School [Quang Ngai], Khai Dinh High School [Hue], and National Academy of Public Administration and College of Law [Saigon], he received two Master's and Ph.D degrees on Administration at the University of Southern California. He spent full time from the age of 72 to 84 researching historical figure Nguyen Van Tuong, collecting documents at the Library of Congress, 5 archives in France, and from archives, conferences and seminars in Vietnam. This book contains original and first-hand histories explored, compared, analyzed and synthesized by the author himself, with the purpose of illuminating the practical line against French colonialism and the infinite sacrifice of the Nguyen court to save the country. The book also purposely addresses historical issues, and provides authentic historical data for the dissertation of Historical Studies, or monographs on historical figures of Nguyen Van Tuong's contemporaries.
