Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945), commonly known by his initials FDR, was an American statesman and political leader who served as the 32nd President of the United States. A Democrat, he won a record four elections and served from March 1933 to his death in April 1945. He was a central figure in world events during the mid-20th century, leading the United States during a time of worldwide economic depression and total war. His program for relief, recovery and reform, known as the New Deal, involved the great expansion of the role of the federal government in the economy. A dominant leader of the Democratic Party, he built the New Deal Coalition that united labor unions, big city machines, white ethnics, African Americans, and rural white Southerners.
