What was the Treaty of Versailles?
Answer
The 1919 peace treaty ending World War I
Explanation
The Treaty of Versailles was the 1919 peace treaty that formally ended World War I between Germany and the Allied Powers. It was signed on June 28, 1919, exactly five years after the assassination of Archduke Franz Ferdinand, in the Hall of Mirrors at the Palace of Versailles outside Paris. The treaty was negotiated during the Paris Peace Conference, which began in January 1919 and was dominated by the Big Four leaders: President Woodrow Wilson of the United States, Prime Minister David Lloyd George of Britain, Premier Georges Clemenceau of France, and Prime Minister Vittorio Orlando of Italy. Germany was forced to sign without participating in the negotiations.
The treaty's most controversial provision was Article 231, the war guilt clause, which required Germany to accept full responsibility for causing the war. Article 232 obliged Germany to pay reparations, eventually set in 1921 at 132 billion gold marks, equal to roughly 33 billion U.S. dollars at the time. Germany lost about thirteen percent of its European territory, including Alsace-Lorraine returned to France, the Polish Corridor and Posen given to a reborn Poland, and the Saar coal basin placed under League of Nations administration for fifteen years. All of Germany's overseas colonies were stripped away and distributed among the Allies as League of Nations mandates.
Military restrictions were severe. The German army was capped at 100,000 men, conscription was banned, the navy was reduced to six battleships, and Germany was forbidden to have submarines, tanks, military aircraft, or any troops in the Rhineland. The treaty also created the League of Nations, an international body designed to prevent future wars through collective security and arbitration.
President Wilson considered the League his greatest achievement, but the United States Senate rejected the treaty in two votes on November 19, 1919 and March 19, 1920, mainly because senators led by Henry Cabot Lodge feared it would compromise American sovereignty. The United States never joined the League of Nations and signed a separate peace with Germany in 1921.
In Germany the treaty was widely seen as a humiliating diktat, and the resulting bitterness, combined with hyperinflation in 1923 and the Great Depression after 1929, helped Adolf Hitler and the Nazi Party rise to power on promises to overturn the Versailles settlement.
Why this matters for your test
This question matters because the Treaty of Versailles is the document that closed World War I and shaped the conditions that produced World War II. USCIS uses it to test applicants on the link between peace settlements, American Senate ratification of treaties, and the failure of collective security between the wars.
