This paper forwards the concept of homohistoricism as a historicism that narrativizes the nation's past as the site of illicit or authentic relations/affections that have the power to pervert or rescue the public sphere in the present-now. In the case of contemporary Turkey, I identify republican, Islamist, and queer homohistoricisms as divergent political projects with interconnected rationales. I analyze two sets of primary materials on queer contention from Istanbul's Gezi Park uprising: Protest records (fliers, brochures, zines, pictures, banners, posters) from Kislak Center's “Gezi Park Protests 2013” collection and the meeting minutes from 657 neighborhood forums produced and archived by the protestors. I argue that queer homohistoricism in Turkey as a contentious repertoire of invoking nostalgic visions of Ottoman cosmopolitanism and urban civility may succeed in authenticating a certain kind of queer politics, but would do so at the expense of perpetuating just as authentic mechanisms of oppression.
