Introduction to International Relations (Vorlesung)

Termin:
wöchentlich | Montag | 10:15 - 11:45 | 06.04.2026 - 10.07.2026 | C HS 3

Inhalt: International politics is a key subject of daily news: from the Russian invasion of Ukraine via the strategic rivalry between the United States and China or the international spread of the coronavirus to the diplomatic haggling in large international negotiations, such as regular United Nations climate negotiations. This lecture gives a systematic introduction to the academic study of international politics focusing on three core areas: war and peace, functional international cooperation, and international political economy. Within each area, first we describe key structures and developments, both historical and contemporary, by drawing on core concepts, second we examine how each of these areas is governed at the international level, and third we introduce the most important explanations that have been developed in each of these areas.

Theories of International Relations (Seminar)

Dozent/in: Tobias Lenz

Termin:
wöchentlich | Montag | 12:15 - 13:45 | 06.04.2026 - 10.07.2026 | C 12.102 Seminarraum

Inhalt: International Relations (IR) is a subfield of political science with a strong theoretical orientation. It includes a wide variety of theoretical approaches that have emerged in response to real-world developments (e.g. the end of the Cold War, 9/11, or the global financial crisis of 2008/09), as well as theoretical and methodological innovations from related fields such as sociology, international law, economics, and political philosophy. Engaging with both “classical” and contemporary theoretical texts is therefore an essential part of a solid education in this field. This seminar accompanies the English-language lecture “Introduction to International Relations.” While the lecture provides short overviews, we will read and discuss selected theory texts in detail. We will explore key IR concepts, including anarchy and the balance of power, various theoretical perspectives on international politics, and relevant historical developments—especially since World War II—as well as current international issues from a theoretical perspective.

Qualitative Methods (Seminar)

Dozent/in: Tobias Lenz, Natascha Zaun

Termin:
wöchentlich | Dienstag | 08:15 - 09:45 | 06.04.2026 - 10.07.2026 | C 14.001 Seminarraum

Inhalt: This module introduces students to a variety of qualitative methods and seeks to encourage their reflective usage and application. After introducing students to the epistemological and methodological differences between qualitative and quantitative methods and the basic rationales for doing each, the course will start with formulating research questions amenable to using qualitative research methods. Subsequently, the course focuses on acquainting students with a core set of qualitative research methods as well as associated designs. Topics covered include single and comparative case studies, (Baysian) process-tracing, ethnography and participant observation, content and discourse analysis as well as interviewing. The course finishes with a concrete application of a selected research method. The course addresses issues not only of methodological foundations and research praxis, but also of ethics and research transparency.
