Who was President during World War I?

Woodrow Wilson served as President of the United States during the entirety of World War I, which lasted from 1914 to 1918. Wilson's leadership was significant during this period, particularly as the United States entered the war in 1917. He articulated a vision for peace with his Fourteen Points, which aimed at establishing a fair and lasting peace after the war. Wilson's administration was characterized by efforts to mobilize the country for war, manage the economy, and promote the League of Nations, an international organization that he hoped would prevent future conflicts.

The other figures mentioned served in different time periods relative to World War I. Theodore Roosevelt was President before Wilson, from 1901 to 1909, and did not have any direct involvement in World War I, although his policies and imperialist perspectives shaped the environment leading up to the war. Calvin Coolidge and Warren G. Harding both served as Presidents during the 1920s, well after World War I had concluded, and therefore played no role in the events of that conflict. Understanding this timeline helps clarify why Woodrow Wilson is the correct choice for President during World War I.
