The primary architect behind the New Deal during the Great Depression was Franklin D. Roosevelt (FDR), who served as the 32nd President of the United States. Elected in 1932, FDR implemented a series of programs and policies aimed at economic recovery, relief for the unemployed, and reform of the financial system. His New Deal included initiatives like the Civilian Conservation Corps (CCC) and the Social Security Act, which aimed to provide immediate aid and long-term economic stability. FDR’s leadership and innovative approaches during this challenging period helped to reshape the role of the federal government in American life and laid the foundation for modern social welfare.
