The Marshall Plan, initiated by Secretary of State George C. Marshall in 1947, aimed to rebuild war-torn Europe and deter communist expansion following World War II, ultimately providing over $12 billion in aid. This U.S. initiative significantly boosted European industrialization and created markets for American goods while precluding Soviet bloc involvement. The plan is recognized as a major humanitarian effort and established the foundation for U.S. foreign aid policies, significantly impacting the region's recovery and preventing the spread of communism.
