Franklin Delano Roosevelt (/ˈroʊzəvɛlt/ ROH-zə-velt or /ˈroʊzəvəlt/ ROH-zə-vəlt; January 30, 1882 — April 12, 1945), commonly known by his initials, FDR, 32nd President of the United States (1933–1945), served for 12 years and four terms until his death in 1945, the only president ever to do so, and 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. A dominant leader of the Democratic Party and the only American president elected to more than two terms, he built a New Deal Coalition that realigned American politics after 1932, as his domestic policies defined American liberalism for the middle third of the 20th century.
