From 1910 to the 1940s, "Progressive" historiography was dominant, especially in political studies. It stressed the central importance of class conflict in American history. Important leaders included Vernon L. Parrington, Carl L. Becker, Arthur M. Schlesinger, Sr., John Hicks, and C. Vann Woodward. The movement established a strong base at the History Department at the University of Wisconsin with Curtis Nettels, William Hesseltine, Merle Curti, Howard K. Beale, Merrill Jensen, Fred Harvey Harrington (who became the university president), William Appleman Williams, and a host of graduate students. Charles A. Beard was the most prominent representative with his "Beardian" approach that reached both scholars and the general public.
