The great depression is the period from 1924 to 1940 in which the economy plummeted and unemployment sky-rocketed. Unemployment reached over 25% in the USA, that is to say more than 13 million people were unemployed.

the case also eliminated maryland's legislation to impose taxes to a national bank, asserting that even though the states retained the power of taxation, the constitution's laws are supreme and can not be controlled by the states, therefore, if a state law contradicts the constitution, it should be declared illegal.
