"European Union" explores the history, purpose, and economic impact of the EU, from its post-war origins to its current complex form. The book argues that while the EU has fostered economic integration and peace, achieving true political unity remains challenging due to strong national identities. Readers will discover how foundational treaties and key figures shaped the Union, and how these historical factors influence today's challenges like Brexit and populism.

The book progresses logically, beginning with the EU's core principles like the Single Market and Eurozone. It then examines the roles of the European Commission, Parliament, and Council. Key chapters delve into economic policies, their effects on member states, and the EU's foreign policy.

The book concludes with an analysis of major challenges, including nationalism and the migration crisis. It offers a balanced perspective, acknowledging both successes and shortcomings, and provides a nuanced understanding of this significant political entity within world history.
