How Many Countries Are In the EU?

With the 2016 departure of the United Kingdom, the geopolitical and economic entity currently has 27 remaining members.

The current EU is the effective result of a number of multilateral trade, customs, and other treaties between various European states between the end of the Second World War and the present time.

In 1957 six core states founded the European Economic Community the predecessor of the European Union (Belgium, France, Italy, Luxembourg, the Netherlands and West Germany. The remaining states have acceded in subsequent enlargements. On July 1st, 2013, Croatia became the newest member state of the EU. In order to accede, a state must fulfill the economic and political requirements which require a candidate to have a democratic, free market government, together with the corresponding freedoms and institutions, and respect for the rule of law.
