The formation of the European Union was influenced by several key political events, including the aftermath of World War II, the desire for economic cooperation, and the need for political stability in Europe. Initially, the establishment of the European Coal and Steel Community in 1951 laid the groundwork for closer integration. The signing of the Treaty of Rome in 1957 created the European Economic Community (EEC), expanding collaboration. Subsequent treaties, like the Maastricht Treaty in 1992, formalized the EU's structure and objectives, enabling deeper political and economic integration among member states.
