The stock market crash of 1929 caused a sharp decline in stock values, contributing to the Great Depression. It was triggered by an overheated economy, overpriced shares, and excessive speculation. The crash resulted in the loss of life savings, job insecurity, and reduced consumer spending. The lack of economic and banking safeguards, along with a pursuit of wealth mentality, also played a role. Stock market crashes occur during unstable economic periods and can be caused by prolonged bull markets and excessive debt. Other factors leading to the 1929 crash were low wages, debt, and a struggling agricultural sector.
