How did the European Union form?

The European Union, or EU, was formed in the aftermath of World War II as a way to foster peace and economic prosperity among European nations. The idea of a unified Europe had been discussed for decades, but it wasn't until the Treaty of Rome was signed in 1957 that the European Economic Community (EEC) was established. The EEC was formed by six countries: Belgium, France, Germany, Italy, Luxembourg, and the Netherlands. The goal was to create a common market where goods, services, and people could move freely across borders.

Over the years, the EEC expanded to include other countries, and in 1993, the Maastricht Treaty established the European Union as we know it today. The EU is based on several key principles, including free movement of goods, services, capital, and people; a single market; and a common trade policy. The EU also has a common currency, the euro, which is used by 19 member states.

Today, the EU has 27 member states, and it has become one of the world's largest economies. The EU plays an important role in international trade and is a major player in global politics. It has also expanded beyond its original goals of economic cooperation and has taken on issues such as climate change, security, and human rights.
