A Christian religious movement that began in the U.S. in the late 19th century and early 20th century to counter liberalism and secularism. It emphasized the inerrancy of the Bible. In recent years, fundamentalist and fundamentalism have become associated with any religious reactionary movement, such as Islamic fundamentalism. The words also have been used as pejoratives. Journalists often, and erroneously, label all conservative Christians, including conservative evangelicals, as fundamentalists. It is best to avoid the words unless a group applies the terms to itself.
