Who served as President during World War I?

Woodrow Wilson served as President during World War I, which lasted from 1914 to 1918. His leadership during this tumultuous period was characterized by his advocacy for a policy of neutrality at the war's onset. However, as the conflict progressed and factors such as unrestricted submarine warfare by Germany and the interception of the Zimmermann Telegram came into play, Wilson shifted his stance and led the United States into the war in April 1917.

Wilson's presidency was marked by significant efforts to influence the post-war world order, notably through his Fourteen Points, which aimed to promote peace and prevent future conflicts. One of his most notable contributions was the establishment of the League of Nations, an international organization designed to foster cooperation and prevent war, although the U.S. Senate did not ratify the Treaty of Versailles, which included the League.

The other presidents mentioned were not in office during World War I. Theodore Roosevelt was in office prior to Wilson, Calvin Coolidge served after the war in the 1920s, and Harry Truman was president after World War II, meaning their presidencies did not overlap with the events of World War I. This context emphasizes Wilson's prominent role and decisions during the war, solidifying his legacy relating
