Eu
In short
The European Union is a political and economic union of 27 member states located primarily in Europe. It operates as a supranational entity that manages shared laws, trade, and economic policies across its territory.
In plain words
It is a group of European countries that work together like a large team. They share a single market to make buying and selling goods easier. They also follow common rules to keep peace and help their economies grow.
A simple example
A person from France can travel to Germany and use the same currency or follow the same safety standards without needing extra permits.
Why it matters
The union accounts for about one sixth of the world's economic output. It allows smaller nations to have a much stronger voice in global trade and politics.
Easy to mix up
Do not confuse the EU with the Eurozone, which only includes the countries that use the Euro currency.
