In Cochinchina, the Lê Văn Khôi revolt (1833–1835) united Vietnamese Catholics, missionaries and Chinese settlers in a major revolt against the ruling emperor, in which they were defeated. Persecutions would follow, leading to the killing of numerous missionaries such as Joseph Marchand in 1835, Jean-Charles Cornay in 1837, or Pierre Borie in 1838, as well as local Catholics.
