The European Union, How It Works, and Its History

How Europe Became an Economic Powerhouse

The European Union is a unified trade and monetary body of 28 member countries. It eliminates all border controls between members. That allows the free flow of goods and people, except for random spot checks for crime and drugs. The EU transmits state-of-the-art technologies to its members. The areas that benefit are environmental protection, research and development, and energy.

Public contracts are open to bidders from any member country.

 Any product manufactured in one country can be sold to any other member without tariffs or duties. Taxes are all standardized. Practitioners of most services, such as law, medicine, tourism, banking, and insurance, can operate in all member countries. As a result, the cost of airfares, the internet, and phone calls have fallen dramatically. 


Its purpose is to be more competitive in the global marketplace. At the same time, it must balance the needs of its independent fiscal and political members.

What Countries Are EU Members

The EU's 28 member countries are: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, GermanyGreece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, and the United Kingdom. That will drop to 27 when Brexit causes the United Kingdom to leave the EU in 2019.

How It Is Governed

Three bodies run the EU. The EU Council represents national governments. The Parliament is elected by the people. The European Commission is the EU staff. They make sure all members act consistently in regional, agricultural, and social policies. Contributions of 120 billion euros a year from member states fund the EU.

Here's how the three bodies uphold the laws governing the EU. These are spelled out in a series of treaties and supporting regulations:

  1. The EU Council sets the policies and proposes new legislation. The political leadership, or Presidency of the EU, is held by a different leader every six months.
  2. The European Parliament debates and approves the laws proposed by the Council. Its members are elected every five years.
  3. The European Commission staffs and executes the laws. Jean-Claude Juncker is the president until 2019. 


The euro is the common currency for the EU area. It is the second most commonly held currency in the world, after the U.S. dollar. It replaced the Italian lira, the French franc, and the German deutschmark, among others.

The value of the euro is free-floating instead of a fixed exchange rate. As a result, foreign exchange traders determine its value each day. The most widely-watched value is how much the euro's value is compared to the U.S. dollar. The dollar is the unofficial world currency.

The Difference Between the Eurozone and the EU

The eurozone consists of all countries that use the euro. All EU members pledge to convert to the euro, but only 19 have so far. They are Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Portugal, Slovakia, Slovenia, and Spain.

The eurozone was created in 2005. 

The European Central Bank is the EU's central bank. It sets monetary policy and manages bank lending rates and foreign exchange reserves. Its target inflation rate is less than 2 percent.

The Schengen Area

The Schengen Area guarantees free movement to those legally residing within its boundaries. Residents and visitors can cross borders without getting visas or showing their passports. In total, there are 26 members of the Schengen Area. They are: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland.

Two EU countries, Ireland and the United Kingdom, have declined the Schengen benefits.

Four non-EU countries, Iceland, Liechtenstein, Norway, and Switzerland, have adopted the Schengen Agreement. Three territories are special members of the EU and part of the Schengen Area: the Azores, Madeira, and the Canary Islands. Three countries have open borders with the Schengen Area: Monaco, San Marino, and Vatican City.

In 1951, the concept of a European trade area was first established. The European Coal and Steel Community had six founding members: Belgium, France, Germany, Italy, Luxembourg, and the Netherlands. In 1957, the Treaty of Rome established a common market. It eliminated customs duties in 1968. It put in place standard policies, particularly in trade and agriculture. In 1973, the ECSC added Denmark, Ireland, and the United Kingdom. It created its first Parliament in 1979. Greece joined in 1981, followed by Spain and Portugal in 1986.

In 1993, the Treaty of Maastricht established the European Union common market. Two years later, the EU added Austria, Sweden, and Finland. In 2004, twelve more countries joined: Bulgaria, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Romania, Slovakia, and Slovenia. 

In 2009, the Treaty of Lisbon increased the powers of the European Parliament. It gave the EU the legal authority to negotiate and sign international treaties. It increased EU powers, border control, immigration, judicial cooperation in civil and criminal matters, and police cooperation. It abandoned the idea of a European Constitution. European law is still established by international treaties. 


Brexit. On June 23, 2016, the United Kingdom voted to leave the European Union. It could take two years to negotiate the terms of the exit. Some EU members asked for an earlier withdrawal. The uncertainty dampened business growth for companies that operate in Europe. 

U.S. companies are the largest investors in Great Britain. They invested $588 billion and employed more than a million people. These companies use it as the gateway to free trade with the EU. Britain's investment in the United States is at the same level. That could impact up to two million U.S. / U.K. jobs. It's unknown exactly how many are held by U.S. citizens. 

The day after the vote, the Dow fell 600 points. The euro fell 2 percent to $1.11. In the face of so much volatilitygold prices rose 6 percent from $1,255 to $1,330. 

What caused Brexit? Many in the United Kingdom, as in other EU nations, worried about the free movement of immigrants and refugees. They don't like the budgetary constraints and regulations imposed by the EU. They want to enjoy the benefits of free movement of capital and trade but not the costs. 

Immigration. In 2015, 1.2 million refugees from Africa and the Middle East poured through its borders. On New Year's Eve 2016, a gang of young refugees robbed and sexually assaulted more than 600 women. As a result, many EU countries sealed off their borders. That stranded 8,000 immigrants in Greece. The EU signed an agreement with Turkey to take back refugees who had reached Greece. In return, the EU would pay Turkey 6 billion euros. In the September 2017 election, opposition to the refugees cost Merkel's party its majority in the government. Immigration is the main reason the U.K.  majority voted for Brexit.

Greek Debt Crisis. In 2011, the Greece debt crisis threatened the concept of the eurozone. It almost triggered sovereign debt crises in Portugal, Italy, Ireland, and Spain. EU leaders assured investors that it would stand behind its members' debts. At the same time, they imposed austerity measures to restrain the countries' spending. They wanted all members to honor the debt limits imposed by the Maastricht Treaty requirements. 

2008 Financial Crisis. In July 2008, the ECB increased rates to 4.25 percent to combat 4 percent inflation caused by high oil prices. The euro strengthened, weakening EU exports. Factory orders plummeted 4.4 percent, the biggest decrease since 2003. 

The ECB switched to recession-fighting in October, when Lehman Brothers went bankrupt. By May 2009, it had lowered the rate to 1 percent. But it began raising rates again too soon. By July 2011, the rate was 1.5 percent, creating a credit crunch and recession. In December 2011, it lowered the rate back down to 1 percent. In March 2015, the ECB began purchasing 60 billion in euro-denominated bonds per month. Its launch of quantitative easing pushed the euro's value down to $1.06 from $1.20 in January. Since then, the euro to dollar conversion has strengthened to $1.23 in April 2018.

In 2007, the EU became the world's largest economy. Its gross domestic product was $14.4 trillion, beating the U.S. GDP of $13.86 trillion. The EU held onto its premier position through the 2008 financial crisis and the eurozone debt crisis. In 2013, the United States briefly regained its leading position. China took over the top spot in 2014. 

The value of the euro continued to rise until the credit crisis in 2007. At that time, there was a flight to safety to the dollar. This strengthened the dollar. The euro's weakness didn't boost exports due to lower worldwide demand.
