The 2004 EU enlargement reunified a continent divided by the Iron Curtain, bringing stability and prosperity to all sides involved. The fifteenth anniversary of the big bang enlargement is an opportunity to reflect on its success, but also to consider the parts of the process that have not gone fully to plan. The perception of an East-West divide in Europe lingers, by some accounts to a surprising extent. What are the lessons learned from the way the EU’s accession and established member states have handled the integration?

Carnegie Europe, in partnership with the Permanent Representation of the Slovak Republic to the EU, hosted a public discussion to take stock of the 2004 enlargement.
