The European Union (EU) is a politico-economic union of 28 member states that are located primarily in Europe. It covers an area of 4,324,782 km2, with an estimated population of over 508 million. The EU operates through a system of supranational institutions and intergovernmental-negotiated decisions by the member states. The institutions are: the European Parliament, the European Council, the Council of the European Union, the European Commission, the Court of Justice of the European Union, the European Central Bank, and the Court of Auditors. The European Parliament is elected every five years by EU citizens.
The EU has developed an internal single market through a standardised system of laws that apply in all member states. Within the Schengen Area, passport controls have been abolished. EU policies aim to ensure the free movement of people, goods, services, and capital, enact legislation in justice and home affairs, and maintain common policies on trade,agriculture,fisheries, and regional development. The monetary union was established in 1999 and came into full force in 2002. It is currently composed of 19 member states that use the euro as their legal tender.
The original European Union (German: Europäische Union) was an antifascist resistance group during Germany's Nazi era, which formed around Anneliese and Georg Groscurth and Robert Havemann. Other important members were Herbert Richter and Paul Rentsch.
The Berlin-based resistance group was founded in 1939. Founding members, Robert Havemann, a chemist and Georg Groscurth, a doctor, met each other at the beginning of the 1930s. Rentsch, a dentist, met Groscurth in 1934. Richter, an architect, was Richter's neighbor. They became friends not because of politics, but because of common interests. They were intellectual, free spirits and came to their political views independently.
Three of the four core members of the EU had direct contact with high-level Nazis. When war broke out, both Havemann and Groscurth tried to extend their work in such a way that they wouldn't be called upon to serve in the military. They took on projects from the Heereswaffenamt, biochemical research that was to put Germany in position to use chemical weapons, but neither they nor other scientists were terribly ambitious about the nominal goal. The architect, Richter, received contracts from the Reichshandwerkskammer and got to know and win the trust of Hermann Göring. He was already interested in the Communist Party and the information he learned from his personal contact with Göring filled him with hate for the Nazis and only pushed him further toward the idea of resistance. Groscurth, a doctor, had both Rudolph Hess and Wilhelm Keppler as his patients.
