Which major event did the Treaty of Versailles seek to conclude?

The Treaty of Versailles was specifically designed to formally conclude World War I, which lasted from 1914 to 1918. Signed on June 28, 1919, it imposed a series of conditions and reparations on Germany and redefined national borders in Europe as a means to ensure lasting peace and prevent future conflicts. Central to the treaty was the idea of holding Germany responsible for the war, which was reflected in the war guilt clause. This represented a significant shift in international relations and set the stage for future geopolitical tensions. The other options—World War II, Cold War, and the Vietnam War—occurred in the decades following World War I and were not directly addressed by the provisions of the Treaty of Versailles.
