“Fighting Bob’s Brother: William T. La Follette, Populism, and Agrarian Progressivism” by Jeff Wells examines the career of a little-known South Dakota politician in the late 1800s and early 1900s. La Follette influenced the rise of agrarian populism and progressivism in the state, forming a coalition between the People’s Party and the Democrats. His actions also swayed the political development of his more famous brother, Progressive senator Robert M. La Follette of Wisconsin. Wells is associate professor and chair of the Department of History at the University of Nebraska at Kearney and associate editor of “Middle West Review.”
