Christian fundamentalism in its modern form began in the late 19th and early 20th centuries among British and American Protestants as a reaction to theological liberalism and cultural modernism. Fundamentalists argued that 19th-century modernist theologians had misinterpreted or rejected certain doctrines, especially biblical inerrancy, which they considered the fundamentals of the Christian faith. A few scholars label Catholics who reject modern Christian theology in favor of more traditional doctrines fundamentalists.
