The main purpose of the Marshall Plan, formally known as the European Recovery Program, was to provide economic assistance to help rebuild European nations devastated by World War II. Instituted in 1948, the plan aimed to restore stability and prosperity to war-torn countries, prevent the spread of communism, and foster economic cooperation. Over $12 billion was allocated to Western European nations, facilitating recovery through infrastructure development, industrial revitalization, and food assistance. This initiative not only helped to revitalize economies but also established strong political alliances and set the stage for future cooperation in Europe.
