Lê Văn Khôi
Converts began to be harassed without official edicts in the late 1820s, by local governments. In 1831 the emperor passed new laws on regulations for religious groupings in Viet Nam, and Catholicism was then officially prohibited. In 1832, the first act occurred in a largely Catholic village near Hue, with the entire community being incarcerated and sent into exile in Cambodia. In January 1833 a new kingdom-wide edict was passed calling on Vietnamese subjects to reject the religion of Jesus and required suspected Catholics to demonstrate their renunciation by walking on a wooden cross. Actual violence against Catholics, however, did not occur until the Lê Văn Khôi revolt.
