The term “fundamentalist” turns 100 next year, and Chris Cantwell is finding new ways to talk about an old term used to describe conservative religions. An assistant professor of history at the University of Wisconsin-Milwaukee, Cantwell can discuss how the word initially emerged to describe a subset of Protestants. He can also speak about how the term “fundamentalism” grew to apply to conservative religion more broadly, and how the fundamentalist appeal to history unleashed what he calls a “politics of nostalgia” affecting today’s political landscape.
