Final answer:
The Treaty of Versailles was the agreement that officially ended World War I. Although the U.S. played a key role in its creation, the Senate rejected it due to concerns over the League of Nations. This decision influenced U.S. foreign policy for years to come.
Explanation:
Treaty of Versailles
The treaty that ended World War I was called the Treaty of Versailles. Signed on June 28, 1919, this treaty officially ended the state of war between Germany and the Allied Powers. Although it was intended to bring lasting peace, many of the terms imposed heavy reparations and territorial losses on Germany, which contributed to future tensions in Europe.
The United States played a significant role in the negotiation of the treaty, largely due to President Woodrow Wilson's Fourteen Points plan that emphasized self-determination, free trade, and the establishment of an international organization for peace, which later became the League of Nations.
However, despite Wilson's involvement, the Treaty of Versailles was ultimately rejected by the U.S. Senate in 1920. Opposition stemmed from concerns about the League of Nations and the impact it might have on U.S. sovereignty, leading to the signing of separate treaties with Germany instead. This rejection marked a significant shift in U.S. foreign policy, moving towards isolationism in the subsequent decade.
