EU Enlargement refers to the process of the European Union (EU) expanding its membership by admitting new countries. This process aims to promote stability, democracy, and economic growth in Europe. Countries that wish to join the EU must meet specific criteria, including adherence to the Copenhagen criteria, which cover political and economic standards. The enlargement process has occurred in several phases since the EU's formation, with notable enlargements in 2004 and 2007, when multiple Central and Eastern European countries joined. Each new member state contributes to the EU's diversity and strengthens its collective influence on global issues, fostering cooperation among European nations.
