Answer:
The Treaty of Versailles, signed in June 1919 was significant because it officially ended World War 1. The treaty held Germany responsible for starting the world with harsh penalties including loss of territory, massive reparations, payments, and demilitarization. Extremely different from President Woodrow Wilson's original idea (outlined in his famous Fourteen Points), the Treaty of Versailles humiliated Germany and failed to outline the issues that started the war in the first place. Economic distress and resentment of the treaty within Germany helped fuel the ultra-nationalist sentiment that led to the rise of Adolf Hitler and the Nazi Party, thus ultimately leading to the start of World War 2.
