A broad, varied collection of political movements of religious and social conservatives arising in the 1970's, and overwhelmingly American and Christian to the point of rendering the descriptions "Religious Right" and "Christian Right" effectively synonymous. (See: "Christian Right.") However, the Religious Right can be said to exist comparatively weakly in nations other than the United States, including Canada and the United Kingdom, and to include individuals and movements informed by Judaism, Islam, Mormonism, and other faith traditions besides Christianity. In the United States, it is closely associated with the Republican Party. The vast majority of members of the Christian Right insist that the United States was founded as a Christian nation. (see AU.org "Is America a 'Christian Nation'")
usage. Also "religious right"
"Proponents of using the term Religious Right argue that in addition to Christians, there are conservative Jews and Muslims active in a broad coalition. Opponents argue that Christians vastly outnumber Jews and Muslims in this coalition, and that using the term Religious Right masks this fact." (Wikipedia "religious right")
note. Not all religious conservatives are political conservatives; not all religious conservatives are members of the Religious Right.
