AbstractThis essay examines Dr. Martin Luther King Jr.’s campaign for President John F. Kennedy to issue a second emancipation proclamation, which involved a series of public speeches delivered across the nation from 1961 through 1963 as well as a 60-page Appeal memorandum composed for Kennedy by Southern Christian Leadership Conference lawyers. King challenged Kennedy’s conservative, accommodating understanding of prudence by harnessing the inventional resources of Civil War centennial commemoration, folding together the past and present to offer a vision of audacious presidential leadership. Examination of this historical moment provides insight into how commemoration creates kairotic opportunities for advocates of social change to renegotiate prudence and call forth new, bolder forms of political action.

Abstract This essay examines the 1959 controversy over whether and how to commemorate the centennial of abolitionist John Brown’s raid on Harpers Ferry. I argue that the controversy arose because commemorating Brown’s raid challenged prominent U.S. public memories of the Civil War that excluded slavery and the continued existence of white supremacy. I analyze the discursive fields into which the centennial commemoration entered: the heroic, patriotic, and unifying narratives of the war championed by the national organizations tasked with commemorating the Civil War centennial, and discourses of the civil rights movement and the black press that demanded a repudiation of white supremacy and the recognition of African Americans as equal citizens. Ultimately, I contend that the rhetoric that surrounded the Harpers Ferry raid commemoration sheds light on how the civil rights movement not only challenged white supremacy in its conservative form, but also pushed against the moderate and liberal manifestations of white supremacy that were embedded in the commemoration of the Harpers Ferry raid.
