How did the regimes affect the world after world war 1?

After World War I, the emergence of various regimes significantly altered the global political landscape. The Treaty of Versailles and subsequent treaties led to the rise of nationalist and authoritarian regimes in Germany, Italy, and elsewhere, contributing to economic instability and social unrest. These regimes often promoted expansionist ideologies, setting the stage for World War II. Additionally, the collapse of empires and the establishment of new nation-states in Eastern Europe and the Middle East created ongoing conflicts and geopolitical tensions that shaped international relations for decades.
