The history of spectacle terror lynching remains one of the darkest and least explored political events in American history. In this article, I explore the aesthetic relation of this history to the formation of notions of public action and political assembly. I argue that the history of spectacle terror lynching establishes both a past and present form of public sovereignty. As such, I attempt to examine questions of what public action means with regard to a political context of antiblack violence. I conclude that lynching festivals constitute not only a form of politics but a form of public sovereignty that is still in play in our notion of the public. At heart this notion informs not only antiblack forms of racism but antiblack forms of genocide.
