Minh Mạng issued an imperial edict, that ordered missionaries to leave their areas and move to the imperial city, ostensibly because the palace needed translators, but in order to stop the Catholics from evangelizing. Whereas the government officials in central and northern Vietnam complied, Duyệt disobeyed the order and Minh Mạng was forced to bide his time. The emperor began to slowly wind back the military powers of Duyệt, and increased this after his death. Minh Mạng ordered the posthumous humiliation of Duyệt, which resulted in the desecration of his tomb, the execution of sixteen relatives, and the arrests of his colleagues. Duyệt's son, Lê Văn Khôi, along with the southerners who had seen their and Duyệt's power curtailed, revolted against Minh Mạng.
