Nothing did more to strengthen determination for academic freedom than the fundamentalist attacks of the 1920s. In opposition to Darwinian evolution, fundamentalists found an issue that combined their alarm over the secular direction of modern culture, their reverence for the Bible, and populist appeals. William Jennings Bryan was especially effective in promoting these concerns. A number of states, especially in the South, adopted legislation banning teaching of evolution in schools. States became focal points for controversy. That is illustrated at the University of North Carolina, where, after a major controversy, antievolution forces did not prevail. Bryan helped trivialize the issue with his populist appeals at the Scopes Trial. The antievolutionist argument that if Christianity was not taught in schools, then neither should anti-Christianity be, effective earlier against Jefferson, pointed to the problem in the twentieth century of maintaining a bland blend of Christian and secular thought.
