The most famous expression was the [[Fourteen Points]] of 1918, that expressed Wilsonian war aims, and which Wilson personally worked to achieve at the Paris Conference of 1919. He was quite successful there but refused to include Republican leaders to help broaden the base of support for Wilsonianism. As a result, [[Henry Cabot Lodge]] demanded amendments to the [[Treaty of Versailles]] that Wilson rejected; the Senate failed to pass the Treaty and the U.S. never joined the League of Nations. Americans of the 1920s and 1930s largely rejected Wilsonianism; in the 1930s isolationism came into fashion. [[Franklin D. Roosevelt]] reinvigorated Wilsonianism by designing the [[United Nations]], this time with Republican advice. The [[UN Charter]] included a veto for the U.S. of the sort Wilson had rejected. | The most famous expression was the [[Fourteen Points]] of 1918, that expressed Wilsonian war aims, and which Wilson personally worked to achieve at the Paris Conference of 1919.
