The first term of the presidency of Franklin D. Roosevelt began on March 4, 1933, when he was inaugurated as the 32nd president of the United States, and the second term of his presidency ended on January 20, 1941, with his inauguration to a third term. Roosevelt, the Democratic governor of New York, took office after defeating incumbent president Herbert Hoover, his Republican opponent in the 1932 presidential election. Roosevelt led the implementation of the New Deal, a series of programs designed to provide relief, recovery, and reform to Americans and the American economy during the Great Depression. He also presided over a realignment that made his New Deal Coalition of labor unions, big city machines, white ethnics, African Americans, and rural white Southerners dominant in national politics until the 1960s and defined modern American liberalism.
During his first hundred days in office, Roosevelt spearheaded unprecedented major legislation and issued a profusion of executive orders. The Emergency Banking Act helped put an end to a run on banks, while the 1933 Banking Act and the Securities Exchange Act of 1934 provided major reforms in the financial sector. To provide relief to unemployed workers, Roosevelt presided over the establishment of several agencies, including the Civilian Conservation Corps, the Public Works Administration, and the Federal Emergency Relief Administration. The Roosevelt administration established the Agricultural Adjustment Administration to implement new policies designed to prevent agricultural overproduction. It also established several agencies, most notably the National Recovery Administration, to reform the industrial sector, though it lasted only two years.
