Alexis Wintoniak offers a detailed account of the European Democrat Union (EDU) and its foundational role in shaping the centre–right political landscape in Europe. Founded in 1978 as a flexible coalition of Christian Democratic, conservative and like-minded parties, the EDU provided an inclusive platform for cooperation at a time when the European People’s Party remained limited to European Communitybased Christian Democrats. Wintoniak retraces the EDU’s evolution—from its early years fostering transnational cooperation, to its focus in the 1990s on supporting fledgling democracies in Central and Eastern Europe. He outlines the EDU’s contribution to party development, institution-building and regional stability, notably in the Balkans and former Soviet states. The chapter explores how changing political realities—EU enlargement, ideological convergence and the waning of Cold War divisions—ultimately paved the way for the EDU’s gradual integration into the EPP, formally completed in 2002. Wintoniak concludes that the EDU’s legacy lives on in its the EPP’ broad reach and leadership, built on the same principles of pragmatism, unity and democratic commitment.
