Coming across a review of Timothy Egan's study of the mid-20th century KKK in the Midwest, having greatly enjoyed the author's 2006 account of the Dust Bowl years, The Worst Hard Time," my expectations were high. Egan is a skillful writer, keeping an overall narrative moving while illustrating it with local events and remarkable personalities. And the story is incredible, if not entirely unfamiliar: in the early 1920's the Ku Klux Klan reached levels of political influence and cultural dominance in Indiana, Ohio, Michigan, and other states in the heartland that exceeded its achievements in the post-Civil War South. Drawing on a wide range of sources, Egan documents the incredible numbers who were members of the "invisible empire": 400,000 in Indiana, maybe half that in neighboring states, with rallies in Indianapolis and Kokomo that drew tens of thousands. The ranks of the Klan expanded to a women's organization and a "Ku Klux Kiddies" club. Any journalist or politician who dared challenge its hegemony was quickly silenced. In Indiana the governor, many mayors, most police forces, and many judges were members. But it all unraveled within a few years when the craven exploitation of followers and sexual predation on young women that had become the standard operating procedure of the Klan's Grand Dragon, D. C. Stephenson, at last came to light, mainly owing to the courage of one young women, Madge Oberholzer, whose physical and psychological injuries while being forcibly captured and raped by Stephenson caused her death, days after she dictated a detailed account of her ordeal. Stephenson was convicted of second-degree murder and given a life sentence, and the Klan gradually diminished across the Midwest. It's a tawdry and instructive tale -- a little heavy on the sordid details for my taste, and I could have done with maybe half as many pages devoted to Stephenson's foibles and follies. But there are disturbing foreshadowings -- not directly noted by Egan, but no doubt anticipated -- of a politician a century later who would suborn politicians, slander judges, and set out to build a political empire accountable to him and his most faithful acolytes alone.
