This article analyses how the EU used this ‘big bang enlargement’ to promote horizontal and vertical expansion to its role as a global development actor. It describes how the Union’s larger membership realised considerable horizontal expansion, primarily by increasing the development cooperation budget managed by the EU institutions. The global financial crisis, austerity measures in its member states as well as legal and institutional changes, however, hampered vertical expansion, with many member states failing to sufficiently increase their own national budgets and efforts to promote coordination and harmonisation delivering limited results. The understanding of the task division between the EU and its member states has evolved with the EU having gained a stronger role as a global development actor in its own right. This article contextualises and describes these expansion patterns by analysing key policy trends in the period 2000–2025 in a historical and international perspective and contributes new evidence to the literature on international organisation expansion.
