Wilson
League of Nations
Treaty of Versailles
President Wilson had a 14-point peace plan, including the creation of a League of Nations. He hoped the League would guarantee the peace, but in the final Treaty of Versailles, the victors of the war insisted on harsh punishment. Even the United States did not support the League of Nations. Today, most Americans accept the United States taking an active role in the world, but at that time they believed otherwise. After the war, the United States had problems with racial tension, struggling farms and labor unrest. After Russia's revolution in 1917, Americans feared the spread of communism. This period is often known as the Red Scare.
