Under Diệm, the Catholic Church enjoyed special exemptions in property acquisition, and in 1959, he dedicated the country to the Virgin Mary.[15] The Vatican flag was regularly flown at major public events in South Vietnam.[16] Earlier in January 1956, Diệm enacted Order 46 which permitted "Individuals considered dangerous to the national defense and common security [to] be confined by executive order, to a concentration camp."[17] This order was used against dissenting Buddhists.[17]
