• The global economic crisis of the 1930s, the Great Depression, exacerbated existing tensions and contributed to political instability, particularly in countries already struggling economically.
• Appeasement policies adopted by some European powers towards aggressive nations, like Germany, failed to deter further expansion, encouraging more belligerent actions.
