The European Union (EU) is a political and economic union of 27 member states located primarily in Europe. It was established in the aftermath of World War II to promote cooperation and stability in the region, and has since evolved into a complex institution with broad powers in areas such as trade, foreign policy, and security. The EU has played a key role in promoting democracy and human rights across Europe, and has worked to address global challenges such as climate change and economic inequality. By fostering collaboration and solidarity among its member states, the EU has become a powerful force for peace, prosperity, and progress in Europe and beyond.
