During whose presidency did the United States implement the Marshall Plan?

The Marshall Plan was implemented during the presidency of Harry S. Truman. This initiative, officially known as the European Recovery Program, was introduced in 1947 and aimed to provide economic assistance to European countries to help rebuild their economies after World War II. Truman recognized that a stable and prosperous Europe was essential for political stability and to prevent the spread of communism. The plan provided significant financial aid to aid in reconstruction efforts, helping to revitalize the economies of Western European nations and foster cooperation among them. Ultimately, it played a pivotal role in the recovery of Europe and strengthening U.S. alliances during the early stages of the Cold War.
