Security rationales continue to gain popularity and political salience, and expand to new policy fields. Today they no longer merely guide defense and diplomacy, but also instruct domains such as migration, health, urban planning, cyberspace and maritime navigation. This course offers an introduction to contemporary security politics and analysis. Its analytical part presents an overview on central theoretical security studies frameworks, exposing students to different ways of conceptualizing threats and risks. Its thematic parts then look at a set of pressing current security topics. They familiarize students with central dynamics (actors, strategies, challenges etc.) in these highlighted subfields, and introduce theme-specific additional analytical tools. The course concludes with a focus on security's tense relations with democratic politics.
