We’re jumping right into our current events coverage with the report involving the European Union. [20] It’s an organization of 28 countries. It’s holding a meeting in Brussels, Belgium this week. [21] And one of the major topics on its agenda is Europe’s ongoing migrant and refugee crisis. There are more people streaming into Europe now than at any point since the Second World War, and there are a lot of disagreements among E.U. members and their citizens about how to address the situation. Another topic involves whether Britain will ultimately remain part of the European Union. Because this is an economic cooperation, the stakes are high.   
What is the E.U.? [22] The European Union is a group of countries that work together to create a single market, to allow goods, capital, services and people to move between the member states, as long as they follow the rules and they pay the entry fee. But we’re getting ahead of ourselves. To start this story, we need to go right back to the end of World War II. After six years of fighting, Europe was disseminated. Economies were collapsing and mistrusts was rife; as old enemies face the prospect of recreating trade ties. France and previous occupiers Germany faced the difficult task of creating a unity for profit. So, they started talking, mainly about steel and coal. In 1951, a total of six countries, France, Belgium, West Germany, Italy, Luxembourg and the Netherlands reached their first accord by uniting the steel and coal industries, creating the European coal and steel community, or the ECSC. They later introduce the European Economic Community, EEC, in 1958. These two organizations are seen as the origin of the modern European Union, which wouldn’t adopt its name until 1993. More than six decades later, the European Union now represents more than half a billion people across 28 countries and with a common currency, the euro, which generates an estimated 14 trillion euros in GDP per year.
