During the 1920s, fundamentalists waged a war against modernism in three ways: by (unsuccessfully) attempting to regain control of Protestant denominations, mission boards, and seminaries; by supporting (with mixed success) Prohibition, Sunday “blue laws,” and other measures defending traditional Protestant morality and sensibilities; and (fairly successfully) by attempting to stop the teaching of evolution in the public schools, a doctrine which they saw as inextricably linked to the development of “German” higher criticism and the source of the Great War.
