    Claimed Legitimacy: Appreciating the Diversity of Regional Organisations

    Regional organisations (ROs) are key actors in global and regional governance, and their authority has continuously grown in all world regions. In the face of growing contestation and politicization, these ROs increasingly justify their right to rule. The GIGA Focus Global analyses their legitimation patterns.

    Sources and Consequences of Legitimation Strategies of Regional Organizations (LegRO)

    In an era of increasing political challenges to global and regional organizations, it is crucial to understand how they claim legitimacy, and how successful they are in this respect. Yet, we know surprisingly little about the sources and consequences of legitimation in most regional organizations around the world. In this project we thus map the legitimation strategies of a sample of 30 organizations and conduct qualitative comparative case studies on major organizations in the Global South.

    Globalisation, Europe & Multilateralism – Sophistication of the Transnational Order, Networks, and European Strategies (GEM STONES)

    The rapid rise in the number of international institutions increases the complexity of the global system. Does this complexity strengthen or weaken the EU's capacity to interact with the world? This is the core question in GEM-STONES, an integrated research and PhD fellowship programme of 15 European institutions, coordinated by the Université Libre de Bruxelles. The two early stage researchers who stay at the GIGA study regional integration processes and regional security governance.
