Through this joint Call for Papers, “Geschichtstheorie am Werk” and “theorieblog”, two blog platforms designed to address basic theoretical questions of their disciplines (history and political science) for a wider audience, invite you to explore how and with what implications historical theory assumptions, historicity concepts and historical narratives have come about in political theory, and conversely ask what political and social-theoretical premises can be identified in academic historiography. Through this two-way observation, the blogs aim to shed light on certain implicit, unconscious or poorly reflected-upon elements of political thinking, historical research and historiography that exert considerable influence. They also hope to make disciplinary blind spots more visible and use the insights gained productively within and across disciplines.
