EU member countries

The EU was not always as big as it is today. When European countries started to cooperate economically in 1951, only Belgium, Germany, France, Italy, Luxembourg and the Netherlands participated.

Over time, more and more countries decided to join. The union reached its current size of 28 member countries with the accession of Croatia on 1 July 2013.
