Woodrow Wilson

Thomas Woodrow Wilson (1856–1924) served as the 28th President of the United States from 1913 to 1921. A former president of Princeton University and Governor of New Jersey, he was elected on the Democratic ticket and is remembered chiefly for his foreign policy doctrine and his role in shaping the post–World War I international system.

On 8 January 1918, Wilson delivered his Fourteen Points address to a joint session of Congress, outlining war aims that included open diplomacy, freedom of the seas, free trade, arms reduction, self-determination of peoples, and—in the fourteenth point—"a general association of nations." These principles became the rhetorical foundation for the armistice negotiations of November 1918 and the Paris Peace Conference that opened in January 1919.

At Paris, Wilson negotiated alongside David Lloyd George (UK), Georges Clemenceau (France), and Vittorio Orlando (Italy) as part of the "Big Four." He secured the inclusion of the Covenant of the League of Nations in the Treaty of Versailles, signed 28 June 1919. However, the U.S. Senate, led in opposition by Henry Cabot Lodge, twice rejected the treaty (1919 and 1920), and the United States never joined the League. Wilson suffered a severe stroke in October 1919 while campaigning for ratification.

Wilson was awarded the 1919 Nobel Peace Prize for his peacemaking efforts. His domestic record is more contested: he resegregated several federal agencies, signed the Espionage Act (1917) and Sedition Act (1918), and oversaw U.S. military interventions in Mexico, Haiti, and the Dominican Republic.

In IR theory, "Wilsonianism" refers to a foreign-policy tradition emphasizing liberal democracy promotion, collective security, self-determination, and multilateral institutions. It is frequently contrasted with realist and isolationist traditions and remains a reference point in debates over American grand strategy.
