It is the single currency of the European Union, which is after the US dollar, as it is the second most important currency in the international monetary system.

Today, the euro is the official currency of 19 of the 28 member states of the European Union.

The acceptance of the euro among the European public varied from one country to another, for example in countries whose currency was low, such as Italy and Greece. The euro came and with it the high prices. On the other hand, such as travel and tourism, the euro was very welcomed by tourists because it saved them from changing the currency and facilitated the task of payment.
