Protestants in Vietnam are a religious minority, constituting from 0.5 to 2% of the population. Though its numbers are small, Protestantism is the country's fastest-growing religion, growing at a rate of 600% in the 2000s. Origin Protestantism was introduced in 1911 at Đà Nẵng by a Canadian missionary named Dr. R.A. Jaffray. As part of the Christian and Missionary Alliance, over 100 missionaries were sent to Vietnam, assisting the faith's growth in the country. During the French colonization, Protestantism was not encouraged; however, it started to spread slowly. By 1928, thirty pastors were authorized to operate in the country by the French local government. Later on, the first Protestant organization recognized by the Vietnamese government was the Evangelical Church of Vietnam: North in 1963. By 1967 information, Protestant communities were represented mainly within South Vietnam. Those communities included the French Reformed Church, Anglican–Episcopalian, Christian and Missionary Alliance, Baptists, Churches of Christ, Worldwide Evangelization Crusade, and Seventh-day Adventists. Other Protestant associations were also represented in some social services and welfare agencies. In 1967 there were 150,000 Protestant adherents in South Vietnam, representing about 1% of the total population. Several Protestant church properties were confiscated during the communist takeover of South Vietnam in 1975, including the seminaries in Nha Trang and Hanoi. Hundreds of Protestant churches were also destroyed in this period. All Protestant denominations in Vietnam were gathered by local communist government into a single organization called the Evangelical Church of Vietnam in 1975, which had around 500,000 official members in 1997. However, in 1988, a house church movement began when some active pastors were expelled from the official churches. One of the most prominent from those pastors was Tran Dinh Ai, whose movement reached 16,000 members and 165 churches (by 1997). Bible societies in Vietnam Protestants made several Bible translations in 1926 and 1991, and translated separate books of Old Testament and New Testament into Vietnamese. The organized work of United Bible Societies in Vietnam began in 1890. In 1966 the Vietnamese Bible Society was established. The Bible societies distributed 53,170 Bible examples and 120,170 New Testament examples in Vietnamese within the country in 2005. Two years earlier, in 2003, 60,000 copies of Bible and 50,000 copies of New Testament (all in Vietnamese) were printed in Vietnam with the permission of local authorities. Same year, 10,000 copies of the Chinese language Bible were printed in Vietnam for the local Chinese
