Europe is a land of many small nations that are very close together, but with many people living there.
Through history, many of the nations have had wars with each other,
but now 28 of the countries have made an agreement to work together
in what they call the
European Union, or just the EU.

Before the EU, countries like Italy had money called the lira, France had the Franc, and Germany had the deutsche mark.
Now many of those countries have accepted a new type of money called the
Euro,
and all the countries in the EU will accept it as money.
