Who was President during World War I?

Woodrow Wilson served as President of the United States during World War I, which lasted from 1914 to 1918. He took office in 1913 and led the nation through the tumultuous period of the war, declaring war on Germany in April 1917. Wilson's leadership was characterized by his efforts to promote peace and diplomacy, which culminated in his Fourteen Points speech, advocating for a vision of a post-war world that emphasized self-determination and the establishment of the League of Nations.

The other individuals listed were not president during this conflict. Theodore Roosevelt's presidency ended in 1909, long before the war began. Calvin Coolidge became president after Wilson, serving from 1923 to 1929, and Herbert Hoover took office in 1929, after the war had concluded. Thus, Wilson’s role as a wartime leader and his pivotal influence on both domestic and international policies during this time solidify his place as the president during World War I.
