I cant say for certain,but it seems that fundamental Christianity is a fairly modern term, 20th century.
Since fundamentalism is a rejection of the modernization of christian theology in the 1800's and 1900's it would need to be a recent term.
This being said, then some of the things that have been attributed to Fundy's isn't so. Is this a flawed line of thought??
Yes and no. Modern christian fundamentalism is a movement to return to previous christian "values" found in earlier centuries. While society moves towards legalization of homosexual marriage there are many fundamentalists that would call for a return to laws that put homosexuals in jail (e.g., Oscar Wilde). They want the church to once again have the political influence it had prior to the modern era.
