The project forms part of a larger research agenda seeking to contribute to the rethinking of modern European intellectual history from the vantage point of crisis-discourses. Combining the methodology of conceptual history with a contextualist history of political thought and with a transnational perspective, it focuses on a number of key controversies that shaped modern East Central European history and politics, seeking to assess continuities and discontinuities. Its three main temporal axes to be analyzed are the interwar era, the socialist period (especially its early and late years), and the years following 2008.
