The Marshall Plan had a transformative impact on post-war Europe by providing substantial economic assistance to rebuild war-torn nations. Initiated in 1948, the plan aimed to prevent the spread of communism by stabilizing economies and promoting prosperity. It facilitated the restoration of production capabilities and improved infrastructure in countries like France, Germany, and Italy. As a result, the plan not only helped revive the European economy but also strengthened political alliances and fostered cooperation, contributing to the eventual formation of the European Union.
