The significance of the Treaty of Versailles in modern politics lies in its role in reshaping the international order following World War I. This treaty imposed heavy reparations and territorial losses on Germany, fostering resentment and instability that contributed to the rise of extremist movements in Europe. Its failure to establish lasting peace and cooperation among nations underscored the need for more effective diplomatic frameworks, ultimately influencing future international agreements. The League of Nations, established by the treaty, marked an early attempt at collective security, shaping the contours of international relations throughout the 20th century and beyond.
