What was the main goal of the European Union when it was formed?

The formation of the European Union was primarily aimed at promoting economic and political integration among member states. This integration sought to foster cooperation and unity in order to ensure stability, peace, and prosperity following the devastation of World War II. By creating a common market, the EU enabled the free movement of goods, services, people, and capital across member states, which in turn facilitated economic growth and strengthened ties between nations.

The political aspect of the integration included the establishment of shared policies and governance structures, which aimed to allow European countries to work together more effectively in addressing common challenges. The EU also aimed to prevent conflicts by fostering interdependence among its members, thereby making war between European countries less likely.

Other options present alternate focuses that do not encapsulate the primary objectives of the EU. While military cooperation is a component of European security dynamics, the specific aim of the EU is centered around economic and political integration rather than forming a military alliance. The idea of a common cultural identity, although beneficial and relevant, is not the central aim of the EU's formation. Additionally, immigration control is a complex issue within the EU framework but is not representative of the main goal upon its establishment.
