Minh Mạng
His governance greatly stabilized and helped develop the Nam Bo region, turning it into a wealthy and peaceful region. In addition, Duyệt opposed Emperor Minh Mạng's ascension and defended Christian missionaries and converts from the emperor's isolationist and Confucian policies. These attitudes brought Duyệt into conflict with Minh Mạng and led to the posthumous desecration of Duyệt's tomb, which provoked his adopted son Lê Văn Khôi to revolt against the court. Later, Emperor Thiệu Trị, the successor of Minh Mạng, rehabilitated Duyệt and restored his tomb.
