				US involvement helped the Allies win the Great War in 1918. The next year, Germany was forced to sign the Treaty of Versailles, acknowledging its guilt in starting the War. Among the Allied signatories was Canada, which had begun to assert its independence from Britain. The US senate, on the other hand, refused to either ratify the Treaty or help guarantee the peace under the newly formed League of Nations, despite President Woodrow Wilson's pivotal role in its construction, marking the beginning of two decades of American isolationism.
