The formation of the European Union was driven by the desire for economic integration and political stability in post-World War II Europe. Economic cooperation began with the **European Coal and Steel Community**, which aimed to prevent conflict by interlinking national economies. The success of these initiatives led to the creation of the European Economic Community in 1957, fostering trade and economic cohesion. Political motivations also included a collective response to the threat of communism during the Cold War. The EU has since evolved into a major entity promoting peace, stability, and cooperation among member states, impacting political and economic landscapes globally.
