This year, the “euro” celebrates its tenth anniversary.
The euro is a unit of money (or “currency”) that is used by 17 countries in Europe.
It wasn’t always that way.
Before the euro, every country had its own currency.
For instance, France had the franc, Italy had the lira, Germany had the Deutschmark and so on.
The euro was created in 2002 when a group of European politicians and financial leaders decided it would be helpful if they had the same type of money.
The idea of the euro was to make it easier for countries to buy and sell more easily between themselves, because they would all be using the same currency.
