The idea of European integration and European unity dates back to old times. However, after World War II, several European countries sought closer political, economical and social coalition with the aim of economic growth and military security. During the mid 20th century, European Coal and Steel Community (ECSC), the European Atomic Energy Community (EAEC or Euratom), and the European Economic Community (EEC) were established by Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany. These institutions were referred to as the “European Community (EC)” which represented the entire European integration. In December 1991, EC concluded to establish an ever-closer union and take further steps for advanced European integration. In 1992, 12 countries of the European Community signed the Treaty of European Union, aka Maastricht Treaty which officially established the European Union (EU). Maastricht Treaty marked the beginning of a new era in Europe. This year, in the ninth edition of KMUN, delegates will be gathered to discuss and shape the foundational treaty of the European Union, and thus the structure of the ever-closer union. Debates and decisions will determine the faith of fundaments the European Union such as EU Citizenship, common currency and central banking system, and a common foreign and security policy.
