Franklin Delano Roosevelt (, his own pronunciation, or ; January 30, 1882 – April 12, 1945), commonly known as FDR, was an American statesman and political leader who served as the 32nd President of the United States from 1933 until his death in 1945. A Democrat, he won a record four presidential elections and emerged as a central figure in world events during the mid-20th century. He directed the United States government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, realigning American politics into the Fifth Party System and defining American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II. He is often rated by scholars as one of the three greatest U.S. Presidents, along with George Washington and Abraham Lincoln.
