Research guide European Union

The European Union is a political and economic union of 28 member states in Europe. The EU operates through a hybrid system of supranational and intergovernmental decision-making. The EU has developed an internal single market (free movement of people, goods, services, and capital) through a standardized system of laws that apply in all member states. The EU maintain common policies on trade, agriculture, fisheries, and regional development, justice and home affairs, common security and defense.
