The main purpose of the Marshall Plan, officially known as the European Recovery Program, after World War II was to provide economic aid to help rebuild European economies devastated by the war. Initiated in 1948 and named after U.S. Secretary of State George C. Marshall, the plan aimed to restore economic stability, prevent the spread of communism, and promote political stability in Western Europe. By providing financial support and resources, the plan facilitated the reconstruction of industries and infrastructure, leading to increased trade and economic cooperation among European nations, ultimately contributing to the formation of modern Europe.
