Nguyen Truong To, Nguyen Lo Trach, Dang Huy Tru, Pham Phu Thu, Bui Vien ... were the major reformers of Vietnam during the Nguyen Dynasty. There have been many books published, many scientific seminars for each of these historical figures; but there was no work or book on the Nguyen Dynasty's responsibility for the patriotic movement and reform in that period. At the request of the work to rethink the historical reform process, to serve the current renovation cause, the historian Do Bang (author of many studies on the Nguyen Dynasty), has assembled the writings of many authors in this book. The content of the book includes some issues such as: Nguyen Truong To's ideological reform of the country; National consciousness in the Nguyen Truong To ideology system; Practical proposals in the thought of Vietnam reform in the late nineteenth century; Imperial court in Hue with the trend of national reform in the second half of the 19th century; Nguyen Dynasty's responsibility in the failure of the reform trend in Vietnam in the late nineteenth century.
