Our Focus

The content focus of CASSIS is, on the one hand, on the interdisciplinary engagement with traditional foreign and security policy topics such as interstate conflicts, competing international order systems, and a return of geopolitics, and on the other hand, on non-traditional security challenges related to space, cyber, climate, and energy security, terrorism, and human security.

This book examines the growing role of “tech middle powers” and their cooperation patterns in a changing global order.

Particularly the contributors analyze the emerging phenomenon of “workarounding”.

Christlicher Widerstand im Nationalsozialismus: Mit Bibel und Pistole im Bendlerblock

Beyond the cultural trap: essentialism and the limits of Global International Relations

Over the past two decades, calls for Global, post-Western and relational reincarnations of International Relations (IR) have elevated culture, civilization and cosmology as resources for decentring Eurocentric canons and pluralizing theoretical vocabulary. Culture, however, is not self-explanatory. It is better understood as a web of historically situated practices, relations and creative acts through which communities negotiate meaning, contest authority and project themselves towards possible futures. When this dynamic, future-oriented and internally contested character of culture is ignored, a ‘cultural trap’ emerges.
