The revolt was put down, and restrictions were placed on Catholicism. Persistent rebellions occurred throughout the Nguyễn Dynasty, many led by Catholic priests intent on installing a Christian monarch. During the French colonial campaign against Vietnam from 1858 to 1883, many Catholics joined with the French in helping to establish colonialism by fighting against the Vietnamese government. Once colonial rule was established, the Catholics were rewarded with preferential treatment in government posts, education, and the church was given vast tracts of royal land that had been seized.
