Who served as President of the United States during World War I?

Woodrow Wilson served as President of the United States during World War I, which lasted from 1914 to 1918. He was in office from 1913 to 1921, and his administration was marked by the United States' entry into the war in 1917, as well as his subsequent efforts to help shape the post-war world. Wilson's leadership during this tumultuous period is significant; he advocated for the League of Nations, which aimed to promote peace and prevent future conflicts. His Fourteen Points, a statement of principles for peace negotiations, also played a crucial role in how the United States approached its involvement in the war and its aftermath. Wilson's presidency thus directly connects to critical developments in both American history and international relations during and after the war.
