Although black people have been members of Mormon congregations since Joseph Smith's time, before 1978, black membership was small. From 1852 to 1978, the LDS Church enforced a policy that restricted men of black African descent from being ordained to the church's lay priesthood. The church was sharply criticized for its policy during the civil rights movement, but the policy remained in force until a 1978 reversal that was prompted in part by questions about mixed-race converts in Brazil. In general, Mormons greeted the change with joy and relief. Since 1978, black membership has grown, and in 1997 there were approximately 500,000 black members of the church (about 5 percent of the total membership), mostly in Africa, Brazil and the Caribbean. Black membership has continued to grow substantially, especially in West Africa, where two temples have been built. Some black Mormons are members of the Genesis Group, an organization of black members that predates the priesthood ban, and is endorsed by the church.
