Leibniz-Institut für Ost- und Südosteuropaforschung (IOS)

What Leibniz-Institut für Ost- und Südosteuropaforschung (IOS) does

Leibniz-Institut für Ost- und Südosteuropaforschung (IOS) is a German non-profit research institute based in Regensburg and a member of the Leibniz Association. It was formed in 2007 through the merger of the Osteuropa-Institut München and the Südost-Institut München, both of which trace their origins to the early 1950s. The institute houses a library of more than 330,000 volumes, including the Wladimir-und-Anja-Peltzer Collection and the Eduard-von-der-Leyen Library, and operates specialised reference databases such as the Amburger Database, BioLexSOE, and the bibliographic reference tools of the Leibniz Open Science portal Regensburg.

IOS conducts interdisciplinary research on East and Southeast Europe in three areas — history, economics, and politics — and runs dedicated digital infrastructure, including GeoPortOst, OstData, and SlideWiki/LOUI. Its business model is institutional public funding: the German federal government and the Free State of Bavaria jointly underwrite the institute under the standard Leibniz funding formula, supplemented by third-party grants from bodies such as the Volkswagen Foundation, DAAD, and BMBF. Outputs include academic publications, policy advice, conferences, fellowships (including programmes for scholars at risk from Ukraine, Belarus, and Russia), and access services for the library and databases. Customers and users are academic researchers, students, journalists, and policy stakeholders, both nationally and across the Eastern European region.

Emerging players

• European Council on Foreign Relations (ECFR): ECFR is a pan-European think tank producing policy research on European foreign policy including Russia, Ukraine, and the Western Balkans. It competes with IOS for media visibility and policy influence on the same set of regional issues.
• Institut für die Wissenschaften vom Menschen (IWM): IWM Vienna is an independent Institute for Advanced Studies focused on the humanities and social sciences in Central and Eastern Europe. It overlaps with IOS in area-studies focus and scholarly publishing while serving a broader regional remit.

Broad incumbents

• Centre for European Policy Studies (CEPS): CEPS is a leading European think tank producing policy research on EU enlargement, the Western Balkans, and EU-Russia relations. As a broader policy-research institution, it overlaps with IOS's applied policy work on EU integration and regional transformation.
• German Institute for International and Security Affairs (SWP): SWP is Germany's largest foreign policy think tank, providing policy advice to the Bundestag and federal government. Its Russia/Eastern Europe division directly competes with IOS for policy influence and parliamentary consulting on the same regions.
• Leibniz Institute for the German Language (IDS): IDS is a Leibniz-affiliated research institute providing institutional infrastructure, library services, and open-access publishing (OPAL) — a useful reference for IOS's role within the wider Leibniz Association research infrastructure ecosystem.

Regional players

• Finnish Institute of International Affairs (FIIA): FIIA is a publicly funded Finnish research institute producing research and policy analysis on international affairs including Russia and Eastern Europe. It is comparable in function to IOS as a state-funded area-studies institute serving policymakers and the public.
• Austrian Academy of Sciences – Institute for Habsburg and Balkan Studies: The Institute for Habsburg and Balkan Studies at the Austrian Academy of Sciences conducts historical and social science research on Southeast Europe. It is a regional peer with overlapping geographic focus and scholarly publishing on the same region as IOS.

Direct peers

• Center for Eastern European Studies (ZOiS): ZOiS is an interdisciplinary research center in Berlin focused on Eastern Europe, particularly the post-Soviet space. As an area-studies research institute serving German and European policy audiences, it directly competes with IOS for visibility, funding, and policy influence.
• Geisteswissenschaftliches Zentrum Geschichte und Kultur Ostmitteleuropas (GWZO): GWZO at the University of Leipzig is a Leibniz-affiliated humanities research institute focused on the history and culture of East Central Europe. It is the closest structural peer to IOS, sharing the Leibniz Association framework, area-studies focus, and library/archival infrastructure model.
• Herder Institute for Historical Research on East Central Europe: The Herder Institute in Marburg is a Leibniz-affiliated research institute with a specialized library and visual archive on East Central Europe. It closely mirrors IOS's combination of regional specialization, library-based research infrastructure, and scholarly publishing activity.
