The European Union is an economic and political union of 28 European countries. The idea of establishing this union dates back to 1958. It began as a purely economic cooperation where countries were keen to cooperate economically in the aftermath of the Second World War to avoid any conflicts that could arise. As a result, the European Economic Community (EEC) was created and started with only six countries: Germany, France, Belgium, Italy, Luxembourg, and the Netherlands.
After the success of the economic power that was formed, the Union expands to become a large international organization, which aims to coordinate and cooperate in the formulation of economic, political, legal, health, environmental, and external policies in addition to security of the Union in full. In 1993, the name was officially changed to the European Union.
The European Union is the most powerful economy in the world, and surpasses the US economy. The EU has a single market, accounting for more than 20% of total world trade. The Union has a single currency called the Euro, which was officially issued on 1 January 1999 and is currently used by 19 out of the 28 countries.

European Union consists of 28 countries. The first batch of countries joined in 1957, which included Germany, France, Italy, Belgium, Luxembourg and The Netherlands. In 1973, Denmark, Ireland and the UK joined. Greece joined in 1981, followed by Spain and Portugal in 1986 and Austria, Finland and Sweden in 1995. In 2004, 9 countries were added, 2 more in 2007, and finally Croatia in 2013 to bring the total to 28.
