What is the European Union and why was it formed?

The European Union was an organization of many countries, mostly in Europe, that created a political and an economic community in Europe. There had been some discussion for many years about creating such a community throughout Europe. By creating the European Union, these countries created a single market for trade. This made it much easier to trade products as many barriers to trade were removed. It also created a single currency that is used by many nations in the European Union. This currency is called the Euro. The European Union also made it easier for people to travel across the borders of the nations in the European Union.
The European Union has several goals. One goal is to strengthen the democratic governance in member nations of the European Union. It also wants to provide for more security for member nations. A third goal is to create economic and financial unity. Finally, the European Union hoped to help member nations become more efficient economically.
