Why did the European Union receive the Nobel Peace Prize in 2012?

The European Union was awarded the Nobel Prize for Peace in 2012 in recognition of the organization’s long-standing efforts to promote peace, reconciliation, and democracy across Europe.1

This honor acknowledged the EU's fundamental role in transforming a continent once defined by conflict into a region of cooperation. By fostering economic and political integration, the organization successfully reconciled former enemies and helped prevent the recurrence of the devastating wars that had historically plagued the region.2
