Think about how different it was when a traveler had to stop at every country’s border to show a passport and to change money to the local currency. Since 2002, the euro has replaced old currencies such as the French franc, the German mark, and the Italian lira.
Adopting the euro is one step in a series of efforts to move Europe toward both economic and political unity. Even the colorful design of the euro coins and bills reflects this effort.
Instead of symbolizing famous people, the coins and bills symbolize European unity by featuring a map of Europe, flags of the EU member nations, and bridges, gateways, and windows. The open exchange of ideas, goods, and money is an outcome of the European Union and has helped Western Europe thrive.
On a high-speed train, travelers can go from one country to another in a matter of hours. Ideas, goods, and raw materials can travel quickly as well.
In addition to the closeness of the countries and the good train service, Western Europe is becoming more prosperous because goods and people can now flow freely across its borders.
Adding to the ease of movement across the borders is the use of a single European currency, the euro.
How has the European Union made the movement of goods, ideas, and people easier?
