The First World War significantly reshaped modern geopolitics by dismantling empires, creating new nation-states, and altering power dynamics. The war led to the collapse of empires such as the Austro-Hungarian, Ottoman, and Russian Empires, resulting in the emergence of countries based on national self-determination. Additionally, the Treaty of Versailles imposed harsh penalties on Germany, fostering long-term resentment that contributed to the rise of extremism and the eventual outbreak of World War II. The geopolitical landscape established post-war still influences contemporary international relations & conflicts.
