The Paris Peace Conference, that sought a lasting peace after World War I, approved the proposal to create the League of Nations (French: Société des Nations, German: Völkerbund) on 25 January 1919. The Covenant of the League of Nations was drafted by a special commission, and the League was established by Part I of the Treaty of Versailles. On 28 June 1919, the Covenant was signed by 44 states, including 31 states which had taken part in the war on the side of the Triple Entente or joined it during the conflict. Despite Wilson's efforts to establish and promote the League, for which he was awarded the Nobel Peace Prize in 1919, the United States did not join the League. Opposition in the U.S. Senate, particularly from Republicans politicians Henry Cabot Lodge and William E. Borah, together with Wilson's refusal to compromise, ensured that the United States would not ratify the Covenant.
