Who was the President of the United States during World War I?

The President of the United States during World War I was Woodrow Wilson. He served as the 28th President from 1913 to 1921 and played a crucial role in leading the nation through the war, which lasted from 1914 to 1918. Wilson is particularly known for his efforts to promote the idea of international cooperation through his Fourteen Points, which he presented as a basis for peace negotiations. His vision of a "League of Nations" aimed to prevent future conflicts and lay the groundwork for international diplomacy following the war's end. This period significantly shaped U.S. foreign policy and its role in the world.

The other options represent presidents who served before or after Wilson's presidency. Franklin D. Roosevelt was in office during World War II, Herbert Hoover was the president just before the Great Depression, and Harry S. Truman succeeded Roosevelt after World War II had ended. Understanding the timeline of these presidents helps clarify why Woodrow Wilson was uniquely positioned as the leader during World War I.
