The European Union (EU) is a group of 28 countries in the continent of Europe. (After Brexit, the membership now stands at 27). After World War II, some European countries came together to form a group to foster economic, social and political cooperation. They saw this as a means to stay united and not go to war with each other.
With France and Germany taking the initiative, four other nations namely Belgium, Italy, Luxembourg and the Netherlands, signed up to form the European Economic Community (EEC) in 1957. It was also called the common market.
The EU has its own currency (euro), own parliament, council and court of justice. It became a single market, allowing goods and people to move around as if they are one nation. The currency euro is being used by 19 member states.
