World War I dramatically altered the geopolitical landscape of Europe, leading to the collapse of empires, significant territorial changes, and the rise of new nations. The Austro-Hungarian, Ottoman, German, and Russian empires disintegrated, resulting in a restructured Europe with new borders. The Treaty of Versailles imposed heavy reparations on Germany, fostering resentment that contributed to World War II. Additionally, new ideologies, such as nationalism and communism, gained prominence. The war also shifted power dynamics and catalyzed movements for independence in colonized nations, laying the groundwork for future conflicts.
