Franklin Delano Roosevelt led the United States through the Great Depression and most of World War II. The only president elected to four terms, he fundamentally expanded the role of the federal government, created the modern American welfare state through the New Deal, and guided the nation to victory as a principal Allied leader. His presidency transformed both domestic policy and the powers of the executive branch.
Born into a wealthy and established Hudson Valley family, Roosevelt was educated at Groton, Harvard, and Columbia Law School. He entered politics as a progressive Democrat, serving in the New York State Senate and as Assistant Secretary of the Navy under Woodrow Wilson.
He was the Democratic vice-presidential nominee in 1920. After contracting polio in 1921, he rebuilt his political career, becoming Governor of New York (1929–1932). His response to the Depression at the state level positioned him for the presidency.
In 1921, at age 39, Roosevelt contracted poliomyelitis, which left him permanently paralyzed from the waist down. He spent years in rehabilitation, particularly at Warm Springs, Georgia. Though he never regained the use of his legs, he carefully managed his public image and rarely appeared in ways that emphasized his disability. The experience deepened his empathy and determination, shaping both his personal resilience and his later political leadership.
Programs such as the Civilian Conservation Corps (CCC), Federal Emergency Relief Administration, and later the Works Progress Administration (WPA) provided direct employment and assistance to millions.
The National Recovery Administration, Agricultural Adjustment Act, and banking reforms (including the FDIC) aimed to stabilize industry, agriculture, and the financial system.
Social Security (1935), the Wagner Act (labor rights), and securities regulation permanently expanded the federal government’s role in economic security and regulation.
Roosevelt gradually moved the United States from isolation toward support for the Allies through measures such as Cash-and-Carry, Destroyers-for-Bases, and Lend-Lease. After Pearl Harbor (December 7, 1941), he led the nation into full-scale war.
He worked closely with Winston Churchill and, more cautiously, Joseph Stalin. Key decisions included the “Germany First” strategy, the planning of major conferences (Casablanca, Tehran, Yalta), and the vision for a postwar United Nations.

Roosevelt was a master of communication (especially the Fireside Chats), political coalition-building, and pragmatic experimentation. He projected confidence and optimism while concentrating significant power in the executive. His relationship with Eleanor Roosevelt expanded the public role of the First Lady.
He permanently enlarged the federal government’s responsibility for economic security and regulation. He helped create the institutional framework of the postwar world (United Nations, international economic system). The 22nd Amendment later limited presidents to two terms in reaction to his four elections. He remains one of the most consequential figures in American political history.
Franklin D. Roosevelt guided the United States through its two greatest crises of the twentieth century: the Great Depression and World War II. Through the New Deal he redefined the relationship between citizens and the federal government. As a wartime leader he helped forge the Allied victory and shape the postwar international order. His four-term presidency expanded executive power, created lasting social programs, and left a complex but unmistakable imprint on modern American government and society.
