The Euro (EUR) is the official currency of the Eurozone, which comprises 19 of the 27 member states of the European Union (EU). It was introduced on January 1, 1999, as an electronic currency and entered into physical circulation on January 1, 2002. The Euro is managed by the European Central Bank (ECB) and the Eurosystem, which includes the central banks of the Eurozone countries.

The symbol for the Euro is €, and it is divided into 100 cents. Euro banknotes are available in denominations of 5, 10, 20, 50, 100, 200, and 500 euros, while coins come in 1, 2, 5, 10, 20, and 50 cents, as well as 1 and 2 euros. The designs on the coins reflect national symbols, while the banknotes feature architectural styles from different periods in European history.

The Euro is the second most traded currency in the world after the US dollar and serves as an important reserve currency. It has simplified trade and travel within the Eurozone by eliminating the need for currency exchange. The value of the Euro is influenced by various factors, including economic data, interest rates set by the ECB, and geopolitical events.
