The situation that contributed to the Great Depression is that people in US speculate nore and more in shares due to the rising shares price caused by economic boom.
However when the economy slowed down people started selling their shares and the number increased in such expotential rate that the prices of shares fell sharply causing the Wall Street Crash.
Many banks then went bankrupt, factories shut down and inflation was high,unemployment also occured to many, and this situation is known as the Great Depression.
