明命帝
After Gia Long, other dynastic rulers encountered problems with Catholic missionaries and other Europeans in Indochina. Gia Long's son, Minh Mạng, was then faced with the Lê Văn Khôi revolt in which native Christians and their European clergy tried to replace him and install a grandson of Gia Long who had converted to Roman Catholicism. The missionaries then incited frequent revolts in an attempt to Catholicize the throne and the country, although Minh Mạng set aside public lands as part of his reforms.
