United Nations Peacekeeping and Conflict Management (UNPAC)
The Research Group United Nations Peacekeeping and Conflict Management (UNPAC) studies the actions and inaction of the United Nations in response to conflict. It focuses on how the UN exercises influence and power through various types of actions, as well as how it responds to challenges of institutional credibility in the process.
The Research Group is funded by a private donation.
It aims to map the repertoire and evolution of UN responses across time and across different pillars of the system, thereby identifying patterns and sources of agency. This is followed by detailed case studies of how certain responses are developed, silenced, or materialized. To tackle these questions, the research group mobilizes diverse methods including Python-based web scraping, qualitative data analysis, process tracing, interviews, and participant observation.
UNPAC research aims to transcend mission-oriented research in peacekeeping by focusing on the spectrum and processes of deploying conflict responses. It seeks to contribute to scholarly and policy debates about UN reform, institutional effectiveness, organizational agency, and the changing nature of contemporary conflicts.

For a long time, the United Nations was widely regarded as the central actor in multilateral conflict management. Yet the number of UN-led peace operations has been in steady decline. Contemporary debates increasingly focus on regional organisations rather than the UN, or on ad hoc arrangements outside any established institutional framework.
This dissertation examines how the roles of four International Organisations engaged in multilateral peace operations — the United Nations, the African Union, the European Union, and the Organisation for Security and Co-operation in Europe (OSCE) — have changed over time. Its theoretical aim is to develop a theory of role change in International Organisations, identifying the conditions under which organisations change their roles and the mechanisms through which such changes occur.
To address these questions, the project harmonises existing datasets on peace operations, enabling systematic comparison of the mandates and operational practices of all missions in which the four organisations have been involved. Official documents, archival materials, Member State statements, and interviews are used to trace role-change processes and assess the conditions under which they take place.
