Franklin Delano Roosevelt (, his own pronunciation, or ) (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. The Coalition realigned American politics after 1932, creating the Fifth Party System and defining American liberalism for the middle third of the 20th century.
