Step-by-step explanation:
The Big Four at the Peace Conference held in Versailles, France, following the end of World War I, were key figures who played a significant role in negotiating the terms of peace. They were President Woodrow Wilson of the United States, British Prime Minister David Lloyd George, French Premier Georges Clemenceau, and Italian Prime Minister Vittorio Emanuele Orlando. On June 28, 1919, they gathered along with leaders of the defeated nations in the Great Hall of Versailles to sign the Treaty of Versailles, officially ending the conflict.
This treaty held significant consequences for Germany and the overall geopolitical landscape after World War I. It included harsh reparations, territorial losses, and the infamous 'war guilt clause' for Germany. While the Treaty aimed to prevent future conflicts, it also planted the seeds for future unrest which culminated in the outbreak of World War II.
