Fundamentalism beliefs, strictly following the Bible, creationism, nativism, and old values, clashed against Modernist ideas, primarily evolution and application of science, in the early 1900s due to differences of opinions. Four issues that reflect this ideological clash are the rise of the KKK, who harbored Fundamentalist and nativist beliefs; the Scopes trial, which pitted the curriculum of John T. Scopes and evolution against Fundamentalism creationism; the Sacco and Vanzetti trial, epitomizing racial bias and prejudice against immigrants; and the Prohibition movement, stemming from the World War I German scare and modernist acceptance against Fundamentalist resistance to alcohol.

The rise of the KKK idealized the Fundamentalist and Modernist clash because of the growing membership and forthright ideals of the group, holding nativist and creationist attitudes and denying evolution. Largely focused in the Midwest and the Bible Belt, the Ku Klux Klan, headed by members such as the Imperial Wizard, Grand Goblins, and King Kleagles, held firm Fundamentalist beliefs and denounced Modernist ideas such as evolution and progression found in alcohol and birth control “experiments.” The KKK was against gambling and adultery as well as anti-Catholic, anti-Jewish, anti-black, and anti-Communist.

These stalwart stands were strictly followed by Klan members and those opposed to these principles would be harshly dealt with, to the point of violence and murder.
