In this opening session of our Spring series "Rapid Response History," Cory Young (History) and Colin Gordon (History) will examine contests or controversies over American History since the nineteenth century. This session is meant to provide a foundation, and historical context, for current controversies over historical interpretation. We are especially interested, as historian Edward Ayers puts it in "four distinct but intertwined forms of remembrance: commemoration, celebration, memory, and history" and in the ways these "four perspectives constantly shift and interconnect, often in surprising ways."
