To many observers, QAnon appeared to burst out of nowhere onto the public scene in 2017. But to historians, QAnon has many familiar elements. In this roundtable, four historians with specializations ranging from the medieval era to the present will discuss how QAnon recycles and recirculates conspiratorial thinking from past eras into a new confection. Thomas Lecaque, assistant professor of history at Grand View University in Des Moines, Iowa, sees QAnon’s deep roots in the violent eschatology of eleventh-century Europe on the eve of the First Crusade. The cult’s anti-Semitism, prophetic preachers, and secular messianic framework all echo this earlier time. Stephanie Richmond, associate professor of history at Norfolk State University, in Norfolk, Virginia, carries the history of QAnon across the Atlantic and forward in time to the nineteenth-century United States. Anti-Catholic and anti-Semitic nativists in the antebellum era frequently invented stories of child sex trafficking, miscegenation, and evil religious forces to attack immigrants, African-Americans, and reformers. Richmond sees direct connections between these beliefs and QAnon’s tenets. Benjamin E. Park, assistant professor of history at Sam Houston State University in Huntsville, Texas, carries the history forward into the twentieth century, identifying QAnon’s more direct antecedents in the anti-communist John Birch Society, and the conspiracy theories voiced by its leading figures, like Ezra Taft Benson, a prominent Mormon and Republican leader. Rachel Hope Cleves, professor of history at the University of Victoria, in British Columbia, Canada, delves into the present, picking up on two central fixations of QAnon discourse: child-saving and the call to “do your research.” What does QAnon discourse say about changing ideas around children, sexuality, and knowledge production in the twenty-first century? Finally, Kristin du Mez, professor of history at Calvin University in Grand Rapids, Michigan, will chair the roundtable, asking questions of the panelists to begin the conversation, then bringing in questions and commentary from the audience. By connecting QAnon to its past, we hope to gain a better understanding of the present movement and its implication for American politics and culture in the years to come. This roundtable is being submitted in conjunction with a second roundtable, organized by Kyle Riismandel, that focuses on QAnon and the history of Satanic panics. Ideally, we hope the two panels could be scheduled sequentially, following chronological logic, with the religion panel first and the Satanic panic panel second.
