New nation-states emerged from former territories of empires like Austria-Hungary and the Ottoman Empire. This shift not only changed political dynamics but also laid the groundwork for ethnic tensions and conflicts that would arise in these newly formed nations.

    • The League of Nations aimed to prevent future conflicts through collective security but struggled with significant challenges that undermined its effectiveness. Key issues included its lack of enforcement mechanisms, reliance on member cooperation, and the absence of powerful nations like the United States. These limitations rendered the League largely ineffective in curbing aggression from countries such as Italy and Japan during the 1930s.
  • Analyze how the economic consequences of WWI contributed to political extremism in Europe during the interwar period.
    • The economic fallout from WWI created widespread discontent and hardship across Europe, paving the way for political extremism.

Disillusioned citizens turned to extremist movements like fascism and communism as they sought solutions to their economic woes, resulting in a volatile political climate that contributed to the rise of totalitarian regimes by the late 1930s.
