The idea of European integration has periodically come to the forefront throughout the centuries. After World War II, the question of "how to prevent this from happening again?" became relentless. The effort that began then, with the ultimate goal of political integration, led to the creation of the Coal and Steel Community, followed by the European Economic Community, and today, the European Union. However, unification has not yet occurred.

On the pages of this book, the disputes within the Union are documented from its inception and during pivotal moments that have defined and continue to influence the common path. Disputes that stem from different perspectives on the common currency, defense integration, German reunification, the management of the crisis in the Eurozone, the role of the EU in the world, and responses to new security challenges.

The book also provides a description of the "Greek adventures" during our country's EU journey. The European Union is an unprecedented historical experiment that, despite its problems, has created unprecedented conditions of peace and prosperity on our continent. What will the continuation of this journey be? The character of the decisions to be made will determine whether unification will be achieved or if the view "everyone can do better on their own" will prevail.
