The Wall Street Crash of 1929 led to the Great Depression, a severe worldwide economic downturn that lasted for most of the 1930s. It resulted in massive unemployment, widespread poverty, and significant changes in economic policy and government intervention. The crash eroded public confidence in the financial system and highlighted the vulnerabilities of capitalism. Consequently, dramatic social and political changes ensued, including the establishment of social safety nets, regulation of financial markets, and a movement towards Keynesian economic principles, shaping modern governance in many countries.
